Rafael Piestun

Research Interests:

The research in Dr. Piestun's group deals with the control and processing of optical radiation at two significant spatial and temporal scales: the nanometer and the femtosecond. Interest in this area arises from the existence of new phenomena occurring at these scales and the fascinating applications in new devices and systems. Current challenges in sensing, imaging, communications, energy conversion, and computing provide a continuous motivation for this work.
