Meet Zainab Nathani: The Illinois Student Turning Sunlight and Humid Air into a Source of Clean Water
At a time when access to safe and reliable water remains one of the world’s most pressing challenges, a high school student from Illinois is exploring an innovative way to turn one of nature’s most abundant resources, the moisture in the air, into drinkable water.
Meet Zainab Nathani, a high school junior from Niles, Illinois, whose groundbreaking research has earned international recognition for developing a material capable of harvesting water from humid air using nothing more than sunlight.
A student at Niles Township West High School, Nathani developed a project titled “Emulsion-Templated Composite Biogels for Scalable Solar-Driven Atmospheric Water Generation.” Her research focuses on porous, bio-based materials designed to capture water vapour from the atmosphere and release it as liquid water when exposed to natural solar heat.
What makes the concept particularly compelling is its potential to operate without conventional electricity or an external energy supply. Instead, the material is engineered to use sunlight as the driving force for releasing the moisture it captures.
From scientific curiosity to a global water solution
Nathani’s interest in water technology did not begin and end in the laboratory. Her scientific work is closely connected to a broader commitment to improving access to clean water.
Her research has focused on water purification and atmospheric water harvesting, an emerging area of science that seeks to collect moisture directly from the air. Rather than depending entirely on rivers, groundwater or conventional desalination systems, atmospheric water harvesting explores ways to capture water vapour already present in the environment.
For Nathani, however, the issue goes beyond scientific curiosity. Through community initiatives and advocacy, she has worked to raise awareness about the importance of clean water and support efforts to bring reliable water sources to communities that need them.
She founded the Niles Area Thirst Project, an initiative affiliated with the international Thirst Project, through which she raises funds to support the construction of clean-water wells in communities without dependable access to safe water.
Her work demonstrates a powerful connection between scientific innovation and social responsibility: researching new ways to generate water while simultaneously supporting communities that lack access to it.
How her innovative material works
Nathani’s research centres on emulsion-templated composite biogels, a type of porous material designed to capture moisture from the surrounding atmosphere.
The material contains a carefully engineered network of pores that allows it to absorb water vapour from humid air. Once the material is exposed to sunlight, the resulting heat causes the captured moisture to be released and collected as liquid water.
The project uses a technique known as emulsion templating, where two normally immiscible liquids are carefully combined to help create a controlled porous structure. By manipulating the structure and characteristics of the resulting biogel, researchers can influence how effectively it captures and releases water.
This approach is particularly significant because the efficiency of an atmospheric water-harvesting system depends heavily on the material’s ability to absorb moisture and then release it efficiently.
Nathani’s research therefore goes beyond simply demonstrating that water can be collected from air. Her work explores how the material can potentially be designed for greater efficiency, affordability and scalability.

International recognition at ISEF 2026
The significance of Nathani’s work was recognised on one of the world’s biggest stages for high school science.
Her project earned a Fourth Award in the Materials Science category at the 76th Annual Regeneron International Science and Engineering Fair (ISEF), held in Phoenix in May 2026.
She reached the international competition after qualifying through the Illinois Junior Academy of Science State Exposition, placing her among students whose research was selected for one of the world’s most prestigious science and engineering competitions for secondary-school students.
The recognition is particularly notable because her project is focused not only on scientific experimentation but also on a problem with enormous global implications.
The word “scalable” in the project’s title is equally significant. It points toward a vision that extends beyond a laboratory experiment. Nathani’s research considers the possibility of developing materials that could eventually be manufactured and deployed on a larger scale.
If technologies of this nature can be made affordable and efficient, atmospheric water harvesting could potentially complement existing water sources in communities facing water stress.
Science with purpose
What distinguishes Nathani’s journey is the relationship between her scientific research and her community service.
While many young researchers become interested in science because of curiosity about how the world works, Nathani’s work is also driven by a practical concern: how scientific innovation can contribute to solving real problems.
Her efforts through the Niles Area Thirst Project reflect that commitment. While her laboratory research explores how water can potentially be generated from atmospheric moisture, her community work supports efforts to provide access to conventional clean-water sources.
The two efforts ultimately address the same global challenge from different directions.
A young leader beyond the laboratory
Nathani’s achievements also extend beyond her research. She serves as President of her school’s Futures in STEM Club, demonstrating leadership among fellow students interested in science, technology, engineering and mathematics.
She is also a three-season varsity athlete, showing that her academic and scientific pursuits exist alongside an active commitment to school life.
Beyond her own studies, Nathani tutors younger students in subjects including mathematics, science, history and language arts, further reflecting her interest in education and mentorship.
She has also expressed interest in becoming a Water Challenge Ambassador, a role centred on empowering communities with knowledge and encouraging young people to take action on global water challenges.
Inspiring the next generation of innovators
Zainab Nathani’s story represents more than an impressive achievement by a high school student. It is a reminder of what can happen when scientific curiosity is combined with purpose, leadership and a desire to create meaningful change. Her work brings together three powerful ideas: innovation, sustainability and service.
By exploring how sunlight can be used to transform atmospheric moisture into usable water, Nathani is contributing to a growing field of research that could have implications for water-stressed communities around the world.
At the same time, her involvement in clean-water advocacy demonstrates that solving global challenges requires more than scientific discoveries. It requires people willing to take those ideas beyond the laboratory and connect them to the needs of real communities. From the classrooms of Niles Township West High School to the international stage at ISEF, Zainab Nathani is proving that age does not have to limit ambition.
Her research may be taking water from the air, but her larger message is grounded firmly on the ground: science becomes most powerful when it is used to improve lives.
