About Me

Collage1_AaswathI am a Research Associate with the Ginzton Laboratory at Stanford University, where I seek to enable new energy and information technologies that harness light and heat using nanoscale optical and photonic devices. By investigating a mechanism known as radiative or sky cooling, and using my background in photonics and heat transfer, I have developed fundamentally new ways of harnessing a ubiquitous and renewable source of energy that remains largely unexploited: the cold of the universe. This has yielded breakthroughs that I am now developing into prototype systems for cooling, refrigeration and beyond. It also remains a core component of my research agenda, with the scope to improve the efficiency of any energy conversion or generation process here on Earth.

More broadly, I am interested in how light and heat can be controlled and better used to enable new technological possibilities for next-generation approaches to energy, information processing, sensing, displays and communication systems. My published research and interests thus span a range of topics, including nanophotonics, photovoltaics, plasmonic structures, metamaterials, and thermal photonics. Developments in these fields have allowed us to control electromagnetic fields in new and extraordinary ways that we’ve just scratched the surface on. They are thus vital and important frontiers of scientific inquiry with the potential for near-term impact in how we deal with a remarkably broad array of sectors in our economy.

I was recently selected as one of MIT Technology Review’s Innovators Under 35 (TR35). For more information about my research projects, please see my publications page and my Google Scholar profile. I can be reached by email at: <myfirstname> at stanford dot edu.

Collage2a_AaswathAn important recent development in our work on radiative cooling was published in Nature late last year. As a first step to harnessing this resource, we demonstrated that sub-ambient radiative cooling to the sky can — counterintuitively — be achieved during the day, even under direct sunlight. Funded by an award from the U.S. Department of Energy’s Advanced Research Projects Agency (ARPA-E), our team is now working to both scale and integrate this technology to improve the efficiency and capabilities of conventional cooling and air-conditioning systems. For a high-level summary you can hear a Nature podcast interview with me and read the official Stanford news release. Other media coverage includes The Economist, CNN, The Guardian, IEEE Spectrum, MIT Technology Review, Ars Technica, Stanford Report, and Christian Science Monitor.
