The Raman lab has moved to UCLA’s Materials Science and Engineering department. Interested students and postdocs are encouraged to email Prof. Raman at aaswath -at- ucla -dot- edu.

At the Raman lab, we seek to understand how light and heat interact with nanoscale photonic devices and materials, with the goal of enabling new energy and information technologies. In particular, we are motivated by the possibility of enabling fundamentally new technological possibilities for next-generation approaches to renewable energy, information processing, sensing, displays and communication systems.

Led by Prof. Aaswath Raman, our research interests span a range of topics, including metamaterialsnanophotonics, photovoltaics, computational methodsmachine learning and energy systems. Developments in these fields have allowed us to control light-matter interaction in new and extraordinary ways that we’ve just scratched the surface of. 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.

In the recent past, a highlight of our work has been in investigating a mechanism known as radiative sky cooling. We have shown that using nanophotonic and metamaterials approaches one can harness a ubiquitous and renewable source of energy that remains largely unexploited: the cold of the universe. You can watch Aaswath Raman’s TED Talk on the subject, as well as a recent presentation he gave at the NYTimes ClimateTECH Conference here.
