Vladimir G. Chigrinov obtained his Ph D degree in solid-state
physics from the Shubnikov Institute of Crystallography, USSR
Academy of Sciences, in 1978. In 1988, he defended his doctoral
degree and became a professor at the Shubnikov Institute of
Crystallography, where he was a leading researcher from 1996. He
joined HKUST in 1999 and is currently an associate professor. Since
1974 Professor Chigrinov has published 2 books. 15 reviews and book
chapters, about 150 journal papers, more than 300 conference
presentations, and holds more than 50 patents and patent
applications in the field of liquid crystals. He is a Senior SID
Member, SID Fellow and an Associate Editor of the Journal of the
Society for Information Display.
Vladimir M. Kozenkov graduated from the Moscow Energetic
Institute as a scientist in applied physical optics (laser
department). For 30 years he worked at the Organic Intermediates
and Dyes Institute (NIOPIK) in Moscow. He pioneered research and
development of various organic photosensitive materials for
holography, waveguide, integral and polarization optics,
stereolithography, optical memory, imaging processing, and security
applications. He was the first to discover the phenomenon of
photoinduced birefringence in polyvinyl-cinnamate films in 1977. He
has published more than 100 refereed papers and holds more than 50
patents.
Hoi-Sing Kwok obtained his Ph D degree in applied physics
from Harvard University in 1978. He joined the State University of
New York at Buffalo in 1980 and became a full professor in 1985. He
joined HKUST in 1992 an is currently Director of the Center for
Display Research (href=’http://www.cdr.ust.hk/’>www.cdr.ust.hk). Professor Kwok
has written over 500 refereed publications and holds 40 patents in
laser optics and LCD technologies. He is a Fellow of the OSA, the
IEEE, and the SID.
