Spotlight on a Young Scientist: Lalita Prasida Sripada Srisai

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.



Name: Lalita Prasida Sripada Srisai

Home: Odisha, India

Age Category: 13-15

Project title: Absorbing water pollutants with corn cobs






Lalita was inspired to find a use for corn cobs, unused agricultural waste, during a conversation with a tribal farmer in a nearby village. Considering the prominence of water pollution in her country, she decided to use the cobs to improve water quality and ultimately provide access to healthier drinking water. She tested several different methods and found that corn cobs can absorb chemicals, detergents and other pollutants directly from the water. Lalita’s project goal is to provide more clean water for nearby villages. 


What was the inspiration behind your project? 

When I was in nursery school, I dressed up as a corn cob and won the prize for the Fancy Dress Competition. Since then, corn has been one of my favourite vegetables. I love roasted, grilled or steamed corn ears, and roasted corn on the cobs is a popular street food in India. Interestingly, all the parts of the corn plant except the actual cobs are useful. I’ve wondered for a long time how to make use of corn cobs. One day I made a hole at the centre of a cob using a screwdriver. Then I poured some dirty water inside the hole and collected the extract from the other end. Surprisingly, the collected extract was devoid of all the suspended particles. This inspired me to search, examine and experiment whether we could clean wastewater by using corn cobs. This could reduce waste by using another form of waste. Luckily, I was supported by my mentor to plan the project in detail and encouraged to participate in this year's Google Science Fair.
Lalita's interest in corn started from an early age
When and why did you become interested in science? 

I am the privileged eldest daughter of my father, who’s a science teacher. Very often he used to take me to the chemistry lab so that I could perform experiments with his students. My frequent visits to the lab packed with variously coloured chemicals attracted my attention since childhood. In my home, I learned how to get around the kitchen from my mother. To me, mixing, soaking, roasting, grinding and baking different ingredients of right proportion to get maximum taste, flavour, energy and above all satisfaction is based more on science than art. Both of my parents ignited my interest in science from a young age.

What words of advice would you share with other young scientists? 

Always observe your surroundings keenly. You never know what scientific breakthrough you may stumble upon.

Spotlight on a Young Scientist: Anika Cheerla

Name: Anika Cheerla

Home:  California, USA

Age Category: 13-15

Project title: Automated and accurate early-diagnosis of Alzheimer's disease



While volunteering in a senior care facility, Anika was shocked to learn how many older adults suffer from Alzheimer's disease. Her curiosity led her to learn more about diagnosis of this disease, and she found that without a standard test or method for diagnosis, most doctors rely on their own opinions. She decided to create a tool that quickly and accurately diagnosed Alzheimer's and knew her brother, who loved science and coding, would be able to help her. By extracting image features from MRI scans, Anika built an interface for doctors to upload an image, enter some basic patient information and get a reliable Alzheimer's diagnosis. 

What was the inspiration behind your project? 

5.3 million Americans are currently living with Alzheimer’s. The disease has killed my great-aunt, hurting my entire family. At the senior home I volunteered at, I met the victims of this illness. With Alzheimer’s everywhere around me, I wanted to make a difference and ease the lives of patients and their loved ones. I found that the majority of patients with Alzheimer’s are not aware of their disease, and therefore don’t get the proper care or treatment. This inspired me to build a tool that gives patients an early and accurate diagnosis of Alzheimer's.

I was also inspired by research carried out by other researchers as part of the SDSS Quasar Lens Search (SQLS). Using an earlier version of the data set I utilized in this project, the SQLS researchers significantly increased the number of known lensed quasars. The success of the SQLS approach inspired me to develop my own method for identifying lensed quasars.

When and why did you become interested in science? 

My brother and I were eating dinner when he asked me the question that would change my life: how does gravity work? I didn’t know the answer, so he made me run around the galaxy (our house) and find space-time (a sheet), a planet (a big ball) and two meteors (small marbles). He stretched out the sheet and balanced the two marbles on the ends of it. Then he made me put the big ball at the center of the sheet. The big ball pushed down on the sheet, and as the smaller marbles rolled down the sheet towards the big ball, I felt omniscient.

I took the materials to school the next day, and explained how gravity works to most of 4th grade. I learned two things from this: One, teaching other people, in a simple way, how complicated matters work makes me look really smart. And two, people actually feel the same wonder and amazement I feel when I learn something new.

This might have been the experience that led me to teach later on in life. This might have been the experience that led me to keep a jar of marbles on my desk. But this was, for certain, the experience that made me question anything and everything in the universe. It was as if the big ball formed an indentation in my head, making the marbles and the tissue (the neurons and the blood) stop in their tracks and start rolling down towards the answers.

What words of advice would you share with other young scientists? 

We now live in an age where the learning process takes minutes. We get easy access to research papers, free courses and a myriad of other resources. When I started this project, I had only a basic understanding of programming and no idea what neural networks were, but from learning from the hard work of other researchers and teachers, I was able to build my tool. What I took from this project, and what people should always remember is that you can stand on the shoulders of giants when you want to touch the stars.

Spotlight on a Young Scientist: Pranav Sivakumar

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.


Name: Pranav Sivakumar

Home: Illinois, USA

Age Category: 13-15

Project title: Automated search for gravitationally lensed quasars


Pranav’s shown interest in astronomy since looking up at the night sky at age 4. He later became interested in physics and worked in a lab focused on quasar research. Certain quasars (massive and extremely remote celestial objects, emitting exceptionally large amounts of energy ) cause an effect called gravitational lensing, which magnifies the light of distant galaxies that would otherwise be too faint to see. Compiling existing data from over 450,000 quasars, Pranav developed two algorithms to automatically find gravitationally lensed quasars and improve the accuracy and reliability of candidates identified for follow-up observations. Pranav’s most excited that his project and results might confirm the expansion of the universe, helping us determine our eventual fate. 

What was the inspiration behind your project? 

When I attended lectures at Fermi National Accelerator Laboratory, I repeatedly heard the phrases “dark matter,” “dark energy” and “future of the universe.” Curious by nature, I asked questions about these topics and eventually learned that very little is known about these two phenomena; in fact, the term “dark” literally describes our limited knowledge of them. I learned that gravitational lensing, which is caused by massive astronomical objects bending light and which results in multiple images of an astronomical light source, is an effective way to study these constituents of the universe. In particular, studying gravitational lensing of quasars, some of the brightest and most distant objects in the universe, may hold the key to understanding our future.

I was also inspired by research carried out by other researchers as part of the SDSS Quasar Lens Search (SQLS). Using an earlier version of the data set I utilized in this project, the SQLS researchers significantly increased the number of known lensed quasars. The success of the SQLS approach inspired me to develop my own method for identifying lensed quasars.

When and why did you become interested in science? 

In the age of the Internet, it’s perhaps ironic that my interest in science started with a book. At the age of seven, I found a book called “Great Physicists” in my house; I picked up the book and found it fascinating.

As my interest in physics grew, I began reading books more focused on astrophysics and cosmology by Michio Kaku. When you see a book at the library titled “Physics of the Impossible,” it’s difficult to ignore!

The lectures at Fermilab were formative in crystallizing my interest in science. Though I understood only one or two words of the science being discussed in the talks, what stayed with me was the energy and excitement of scientists challenging each other in the room.

Science feeds my curiosity by allowing me to ask complex questions, challenge assumptions and explore interesting topics without worrying about assignments or tests. It’s like a jigsaw puzzle; there’s a great amount of satisfaction when the pieces start fitting together.

The “Aha” moment is priceless – just ask Archimedes!

What words of advice would you share with other young scientists? 

I learned from experience that starting small and building up to complex questions works best for young scientists. Feel confident about connecting with professionals – initially, it may be scary, but their willingness to help and their mentorship are worth much more than those few moments of anxiety.

When I ran into a technical roadblock, I contacted the primary researcher on the SQLS team in Japan; within 24 hours, he responded with valuable suggestions that I’m still pursuing to this day.

Spotlight on a Young Scientist: Alexey Tarasov

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.






Name: Alexey Tarasov (Алексей Тарасов)

Home: Moscow, Russia

Age Category: 13-15

Project title: Using ternary logic on current electronics








Alexey had always been a computer science fan, but it was fixing a computer that really sparked his curiosity. He wondered why all modern day computers ran on binary logic, and if there might be a benefit to using ternary logic. Once he found out that a vintage USSR computer did, in fact, rely on ternary logic, he knew he wanted to test this logic on current electronics. Alexey’s model successfully used ternary logic, and he’s excited to create new ternary logic elements for integrated circuits and computer systems. 

What was the inspiration behind your project? 

I was inspired by the old Soviet project called "Setun."

When and why did you become interested in science? 

All my life I was interested in engineering. I was very interested in the structure of different devices and desired to create. This is what pushed me to study technologies.

What words of advice would you share with other young scientists? 

It's not enough to just discover something new. You need to make it useful for mankind. Good luck!

Spotlight on a Young Scientist: Eliott Sarrey

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.



Name: Eliott Sarrey

Home: Lorraine, France

Age Category: 13-15

Project: Bot2Karot: gardening through a smartphone-activated robot





Eliott loved the idea of gardens, but not the time commitment needed to tend them. He wondered whether he could apply his knowledge and passion for video games and video programming towards growing vegetables. With help from his father, he built a rolling robot controlled by a smartphone app he created. Since the manufactured Bot2Karot can use its manufactured arms and tool holders to hoe, water and transplant, Elliot’s extremely excited about the possibilities with his own robot. He believes he can broaden his initial aim to help people with limited mobility and access. 


What was the inspiration behind your project?

People I know spend a lot of time on gardening simulators (games). On the other hand, my family’s actual garden requires a lot of real work and attention. After careful observation, I wondered whether I could mix the idea of the gardening game with the fun of having real vegetables to eat. What if we could create a robot to take on cumbersome gardening tasks using our smartphones, so that gardening becomes a smartphone game?

When and why did you become interested in science? 

When I was quite young, I spent a lot of time in my father’s small workshop. I also liked to play Legos, and with this experience, I could dig into subjects like mechanics and physics. Three years ago, together with friends, I created a computer science club and a robotic club at my high school. That’s where I learned how to program. At home, I created small robots and robotic arms, which became the real inspiration for my project.

What words of advice would you share with other young scientists?

First of all, be curious! That’s how you come up with ideas. Seek solutions and always ask yourself how to improve on them. Once you have found your idea, do some research, persevere, investigate other solutions and keep optimizing your solution.

Spotlight on a Young Scientist: Calvin Rieder

Name: Calvin Rieder

Home: Ontario, Canada

Age Category: 16-18

Project title: Extracting clean water from air: solar-powered solution for providing potable water


Calvin once saw a camping trick that transformed air into water. The power of that simple trick stuck with him, and then he realized it just might save lives. He decided to use that model to help provide safe drinking water to the billions around the world with limited access to clean water. Without a lab, Calvin built a model at home (powered by the sun) to extract water from the air without external energy or mechanical assistance. Calvin was extremely excited to see that his condensation model produced water for 12.5 hours per night. He looks forward to the impact his model could make for those in need of our most necessary natural resource.


What was the inspiration behind your project? 

When deciding on my first science fair project, my main focus was to address a significant global challenge. I chose the global water crisis as my subject after learning that over 1 billion people lack access to sufficient clean water. I was also shocked that a child dies every minute from a water-related disease and that in some areas of the world women spend up to twelve hours a day walking to obtain water. I decided to try to create devices that could produce potable water from the atmosphere at low cost to improve water access for some of these people. Around that time, an earthquake struck Haiti, and I remember thinking that the devices I was developing, which did not require infrastructure, could also be useful in this type of disaster situation. In the majority of water shortages, those most affected are those who are impoverished and cannot afford water production systems with running costs. In addition, frequently these people live in areas without infrastructure. I also decided that any system I would create would have to have no negative impact on the environment, as I didn’t want to create new problems while solving an old one. For these reasons, I decided that the devices had to operate without an electrical power source or infrastructure. Finally, while my devices were attempting to address the problem of water scarcity, millions only have access to contaminated water, and 2.5 billion people live in areas with inadequate sanitation. I also wanted to address this huge problem, again without electrical assistance or a requirement for infrastructure. For this reason, I developed an efficient, new solar still which uses solar energy to convert contaminated water into potable water.

When and why did you become interested in science? 

I have always been interested in how things work, in constructing new things. From a young age, I loved kids’ science shows. When I was 6 years old, I became fascinated with marine biology, starting with sharks, and I’m still very passionate about this subject. In Grade 7, our school held a science fair that I found success in, and this experience motivated me to continually improve my work and participate in several successive science fairs. My interest and passion for science continues to increase with each fair that I participate in. I consider these amazing opportunities to learn and explore.

What words of advice would you share with other young scientists? 

Work hard and persist, because when researching, things rarely happen overnight. So you get what you put into it. Also, don’t be afraid to think big and take on problems that seem beyond your ability to solve, because often small ideas can lead to significant new solutions. Finally, never become disheartened by failure or problems that arise in your work, as it’s all part of the process.

Spotlight on a Young Scientist: Olivia Hallisey

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.



Name: Olivia Hallisey

Home: Connecticut, USA

Age Category: 16-18

Project title: Temperature-independent, inexpensive and rapid detection of Ebola

Olivia was shocked to learn about the Ebola epidemic spreading through Africa. She wondered how to get treatment delivered faster to the people that needed it and recalled her science lesson about silk storage. With it’s stabilizing properties, could silk allow Ebola antibodies to travel much longer without the need for refrigeration? After a few attempts, Olivia created the Ebola Assay card – her new antibody storage system that can be designed in 30 minutes anywhere in the world and can transport vaccines/antibodies for Ebola, HIV and other diseases for up to one week.


What was the inspiration behind your project? 

My decision to focus my project on the development of a novel temperature-independent, rapid, portable and inexpensive diagnostic test for the detection of the Ebola virus, was prompted by the devastating loss of life in Africa during the most recent 2014 Ebola outbreak. The consequences will be far-reaching with valuable applicability as an ELISA-based diagnostic for other diseases, including HIV, lyme disease, yellow fever, dengue fever and certain cancers. The concentration of fatalities in Ebola stricken areas has left many children orphaned, and the socioeconomic fabric of entire villages destroyed. School closures have impacted over five million children, risking permanent educational dislocation and high risk behaviors such as child labor. Early diagnosis and proper medical care are critical to containing and eliminating the spread of Ebola and any other contagious illnesses.

When and why did you become interested in science? 

I became interested in science as a young child because of my late grandfather, a doctor and medical researcher. He showed me the power of science and research to make new discoveries that could lead to breakthroughs that could give back hope and transform futures. He was passionate about science and medicine and cared deeply that his work would contribute towards a greater understanding and a cure for diseases such as Cystic Fibrosis and Alzheimers. I hope to be a doctor like my grandfather, and one day work for a global health organization, such as Doctors Without Borders.

What words of advice would you share with other young scientists? 

Think globally. Reconsider existing solutions and always ask “Why not?” Don’t think that everything that can be done has been done. There’s always room for innovation and creative reconsideration. Everyone has a role in change.

Spotlight on a Young Scientist: Deepika Kurup

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.



Name: Deepika Kurup

Home: New Hampshire, USA

Age Category: 16-18

Project title: Solar powered silver combating bacteria in drinking water




During her family summer visits to India, Deepika was troubled to see small children drinking polluted water from streams. She wondered how developing countries could best clean their water, and once returning to the U.S. tested different chemicals. She found that a solution mixed with silver and powered by the sun removed bacteria faster than current methods. With this finding, she hopes to provide cleaner drinking water to families in India and around the world. 

What was the inspiration behind your project? 

Every summer my family and I travel across the world to visit India. In America, I always had the privilege of having unlimited access to potable water; however, in India I saw children drink water that I felt was too dirty to touch. I wanted to find out why these people lacked access to safe water, a substance that’s essential for life. I learned that we’re facing a global water crisis. According to the World Health Organization, one-ninth of the global population lacks access to clean water. This unacceptable social injustice compelled me to find a solution to the world’s clean water problem.

When and why did you become interested in science? 

I’ve always been curious about the world around me. When I was younger, I’d constantly ask my parents questions about how the world works, and their explanations were often rooted in scientific concepts. As I grew, I began to notice that science is truly everywhere. After hearing about scientific discoveries on the news and reading stories of famous scientists in the past, I realized that science has the power to lead us to revolutionary new discoveries that can change the world. This passion for science, combined with my interest in solving global challenges, is what sparked my interest in research.

What words of advice would you share with other young scientists? 

I would strongly encourage other young scientists to continue to pursue their passions in science, technology, engineering and math. While scientific advancements are being made every day, our world still faces several grand challenges. We need young scientists to solve these grand challenges, as science has the power to help people find solutions to problems we never thought could be solved.

Spotlight on a Young Scientist: Zhilin Wang

Editor's note: We're celebrating this year's impressive 20 Google Science Fair finalist projects over 20 days in our Spotlight on a Young Scientist series. Learn more about each of these inspiring young people and hear what inspires them in their own words.


Name: Zhilin Wang

Home: Singapore

Age Category: 16-18

Project title: Zinc air batteries for affordable, renewable energy storage 


Zhilin has used his large capacity for wonder to question everything since he was a young boy. This strong curiosity for not just what goes on around him but what happens in other countries led him to understand how developing countries access renewable energy. To speed up the slow chemical reaction produced by oxidizing zinc with oxygen from the air, Zhilin built an aerogel consisting of carbon nanotubes and graphene. His gel sped up the oxidation process, allowing faster storage of renewable energy. He looks forward to testing his aerogel in villages that don’t have electricity – rather than the multiple sources we rely on today. This system, with a little more development, could have expansive use in areas ranging from wearable computing to location-based applications, where an instant and accurate indoor 3D positioning system is in high demand.

What was the inspiration behind your project? 

Looking at the world around me, I can’t help but marvel at how far our search for novel materials has come to improve our everyday living. Nowadays, such materials are literally everywhere: in our smartphones, our clothes and even, for some of us, our bodies. Once in a while, when I find out about a novel material, I get really excited and dream about how it might shape our future.

Graphene aerogel is one such material. Think about this: you have a solution of graphene and a solvent, say water. If you can remove the solvent to leave behind only the graphene framework (or more illustratively, a graphene skeleton), you have yourself a graphene aerogel with some curious characteristics. It is super conductive, ultralight – reaching below the density of atmospheric air in some samples – and has a contact surface area matched by few. This means that it can potentially make astounding improvements in many of the things we use on a daily basis. I was eager to see if it can be applied to something that it had never been tested on before. So when a need for improving the efficiency of batteries came my way, I thought, “why not use graphene aerogel?”

With a stroke of luck, the graphene aerogel turned out to be suitable for the battery. Yet, I didn’t want to end my project there; I wanted to see if the improved battery could directly impact the lives of people. Having reflected upon some of the things I was grateful for, I realized that one of the most wonderful gifts I have received is a quality education. Without it, I wouldn’t have been able to read my favorite books, learn so much about the world or even participate in this competition. Yet, many in underdeveloped regions do not receive basic education. Despite the promotion of global education, a great deal of children are forced out of school to support their families by working on farms or in factories. The only time they could spare for education is in the evenings but even then, the scarcity of reliable lighting means they’re unable to learn in the dark, as much as they want to. Can my battery be used to light up their nights? I didn’t know for sure, so I tried to find out.

When and why did you become interested in science? 

My love for science started around the time I was in primary school, when I found myself so curious about everything around me. You can say that every opportunity for me to discover something new was as irresistible as a candy laid before me. Of the many things I wanted to know, scientific demonstrations particularly piqued my interest. They seemed almost magical – water instantly freezing on a hard knock, violent fountains formed from Coca Cola and mints. But I wasn’t satisfied with merely marveling at them. I wanted to appreciate their inner beauty and understand how they actually worked. For me, science is about having a passion for the beauty of the world around us and understanding how and why things happen in it. Isn’t that much more interesting than simply accepting things as they are?

What words of advice would you share with other young scientists? 

Never be afraid to ask questions concerning things you are curious about, for what lies ahead is either a path of discovery or at least the joy of learning something new.

Irish students win the 2014 Google Science Fair

Ciara Judge, Émer Hickey and Sophie Healy-Thow became interested in addressing the global food crisis after learning about the Horn of Africa famine in 2011. When a gardening project went awry, they discovered a naturally occurring bacteria in soil called Diazotroph. The girls determined that the bacteria could be used to speed up the the germination process of certain crops, like barley and oats, by 50 percent, potentially helping fulfill the rising demand for food worldwide. Oh—and they’re 16 years old.

Today, Ciara, Émer and Sophie were named the Grand Prize Winner and the 15-16 age category winners of our fourth annual Google Science Fair. They are some of thousands of students ages 13-18 who dared to ask tough questions like: How can we stop cyberbullying? How can I help my grandfather who has Alzheimer's from wandering out of bed at night? How can we protect the environment? And then they actually went out and answered them.

From thousands of submissions from 90+ countries, our panel of esteemed judges selected 18 finalists representing nine countries—Australia, Canada, France, India, Russia, U.K., Ukraine and the U.S.—who spent today impressing Googlers and local school students at our Mountain View, Calif. headquarters. In addition to our Grand Prize Winners, the winners of the 2014 Google Science Fair are:
  • 13-14 age category: Mihir Garimella (Pennsylvania, USA) for his project FlyBot: Mimicking Fruit Fly Response Patterns for Threat Evasion. Like many boys his age, Mihir is fascinated with robots. But he took it to the next level and actually built a flying robot, much like the ones used in search and rescue missions, that was inspired by the way fruit flies detect and respond to threats. Mihir is also the winner of the very first Computer Science award, sponsored by Google.
  • 17-18 age category: Hayley Todesco (Alberta, Canada) for her project Waste to Water: Biodegrading Naphthenic Acids using Novel Sand Bioreactors. Hayley became deeply interested in the environment after watching Al Gore’s documentary “An Inconvenient Truth.” Her project uses a sustainable and efficient method to break down pollutant substances and toxins found in tailing ponds water in her hometown, a hub of the oil sands industry.
  • The Scientific American Science in Action award: Kenneth Shinozuka (Brooklyn, New York) for his wearable sensors project. Kenneth was inspired by his grandfather and hopes to help others around the world dealing with Alzheimer's. The Scientific American award is given to a project that addresses a health, resource or environmental challenge.
  • Voter’s Choice award: Arsh Dilbagi (India) for his project Talk, which enables people with speech difficulties to communicate by simply exhaling.
As the Grand Prize winners, Ciara, Émer and Sophie receive a 10-day trip to the Galapagos Islands provided by National Geographic, a $50,000 scholarship from Google, a personalized LEGO prize provided by LEGO Education and the chance to participate in astronaut training at the Virgin Galactic Spaceport in the Mojave desert.

Thanks to all of our young finalists and to everyone who participated in this year’s Google Science Fair.
