RESEARCH AND INTERESTS
Dr. Raman’s research explores how light and heat can be controlled at the nanoscale to enable new technological possibilities for cleaner energy, information processing, sensing, displays and communication systems. His research group’s interdisciplinary interests include metamaterials, nanophotonics, photonic materials, plasmonics and new computational and machine learning methods. A highlight of his recent work has been initiating an emerging field of research, and a new approach to energy efficiency and generation, known as radiative cooling. Using nanoscale photonic materials, his research has explored how to harness a ubiquitous and renewable source of energy that remains largely unexploited: the cold of the universe.Dr. Raman’s group has openings for postdocs and graduate (M.S./Ph.D.) students, as well as undergraduates. Students with backgrounds in Optics & Photonics, Physics, Electrical Engineering, Materials Science and Engineering, Mechanical Engineering and related fields may send their CV and a short statement of interest to aaswath@ucla.edu.Area of Thesis Guidance: Metamaterials, Optical and Photonic Materials, Nanophotonics, Plasmonics, Thermal Sciences, Energy Systems, Computational Methods
