====== Zhengyun Zhang ======

===== Biography =====
I am a research scientist at the Singapore-MIT Alliance for Research and Technology (SMART) Centre in the BioSystems and Micromechanics (BioSyM) interdisciplinary research group. I received my Ph.D. in Electrical Engineering from Stanford University. My research interests are in computational approaches to optics, with particular focus on coherence and phase retrieval, numerical optimization, phase space and three-dimensional display.
