Dr. Ragip Pala

Senior Research Scientist

Nanophotonic Materials and Devices


Dr. Ragip Pala is currently a Senior Research Scientist in the Atwater Group within the Department of Applied Physics and Materials Science. Dr. Pala received his Ph.D. in Applied Physics from Stanford University. At Stanford, he worked in the Nanophotonics Laboratory (with Prof. Mark Brongersma). He also holds BS degrees in Mathematics and Physics from Middle East Technical University, Turkey.

His current research interests include resonant photonic systems for imaging, bio-sensing and energy applications, functional two-dimensional material systems for advanced optoelectronic devices and novel characterization techniques for nanoscale analysis and discovery of new materials.

His research experience spans the design and demonstration of novel light trapping systems for photovoltaic devices, nanoscale plasmonic systems for integrated photonic circuits and development of new spectroscopic methods for optical and electrical characterization of emerging materials. He has authored or co-authored more than 30 peer reviewed research articles in major journals and conferences.

Dr. Pala is a recipient of the Stanford Graduate Fellowship and a member of OSA (Optical Society of America)SPIE (The International Society for Optical Engineering)APS (The American Physical Society), and MRS (Materials Research Society). He was the vice-president of OSA Student Chapter at Stanford University.
