Aaswath Raman

Aaswath Raman is Assistant Professor of Electrical and Systems Engineering at the University of Pennsylvania. 


He leads a research group that seeks to understand how light and heat interact with nanoscale photonic materials and devices, with the goal of enabling new energy and information technologies. 

In particular, he is motivated by the possibility of enabling fundamentally new technological possibilities for next-generation approaches to renewable energy, information processing, sensing, displays and communication systems.

He has published more than 25 peer-reviewed publications that have been cited more than 2200 times in leading journals including Nature, Nature Energy, Proceedings of the National Academy of Sciences, Physical Review Letters and Nano Letters.  He received his Ph.D. in Applied Physics from Stanford University in 2013, and an A.B. in Physics and Astronomy and M.S. in Computer Science from Harvard University in 2006.

He is also Co-Founder and Chief Science Officer of a clean energy startup, SkyCool Systems, where he was also its founding CEO. He initiated and led the development of radiative sky cooling, a technology that he originated as a research associate at Stanford University beginning in 2012. Raman is deeply interested in the intersection of science, technology and development work, and he has previously collaborated on projects to redesign refugee camps with UNHCR and to rethink governance in rural Sierra Leone. He was previously a Program Manager at Microsoft working on the Bing search engine. 

Raman received the Sir James Lougheed Award of Distinction, a Ph.D. fellowship from the Government of Alberta, Canada, and the SPIE Green Photonics Award for his work on light trapping in solar cells, both in 2011. In recognition of his breakthroughs in developing radiative sky cooling, in 2015 he was named one of MIT Technology Review’s “Innovators Under 35” as a pioneer in energy. In 2018, he was invited to speak at TED 2018.
