Vassili Sergan, Professor of Physics at California State University, Sacramento started his scientific career in 1984 after graduating Rovno State University (Ukraine) with master’s degree in Math and Physics. His research (at Institute of Physics, Ukrainian Academy of Sciences) in the area of electro-optics of Liquid Crystals (LC) earned him PhD in Solid State Physics in 1990. After that he occupied various visiting research positions around the world, while maintaining his principal appointment as a senior research fellow at Institute of Physics, Ukrainian Academy of Sciences. His main research focus was always related to electro-optics of Liquid Crystals: improvements of PDLC, studies of switching dynamics of cholesteric displays, using LC in laser beam steering devices, studies of alignment and anchoring of LC on various surfaces, implementation of polymer-doped LCs, just to name few.
In 2002, Vassili Sergan joined Physics and Astronomy Department at California State University, Sacramento. His main responsibility there is teaching, but he manages to maintain an active research program there. His publication portfolio contain more than 50 papers in highly regarded journals, several US and European patent. He presenter his work at numerous international conferences and Symposia.
