Viktor Gruev

Associate Professor
After completing his PhD, Professor Gruev was a postdoctoral researcher in the Department of Electrical and Systems Engineering at the University of Pennsylvania. During his postdoctoral period, Professor Gruev worked on CMOS image sensors, polarization imagers and micro/nano fabrication technologies. Professor Gruev joined the Department of Computer Science & Engineering in August 2008.
Professor Gruev's research interests are in the area of low power integrated sensory systems. In particular, his research aims to synergistically combine CMOS mixed signal electronics with emerging polymer and nano technologies. Professor Gruev's main research area is development of novel image sensors and computational image sensors in CMOS technology. His research interests also include: integrated polarization imaging, focal plane spatiotemporal image sensors, current mode image sensors, sensory systems in 3-D fabrication technology, micro/nano fabrication, micro fluidics, and low power analog/digital integrated circuits.
