I'm an Assistant Professor in the
Dept. of
Physics at Rutgers-Camden. I'm a physicist. I teach lower and upper
level undergraduate physics courses. My current research interest
include electro-optical and thermal properties of ferroelectric and
nematic liquid crystals. Particularly, my interest include the liquid
crystal nanocomposites and their potential application in
electro-optical devices. My interest include also
electro-optical
properties of Holographically formed Polymer Dispersed Liquid Crystals
(H-PDLC switchable Bragg gratings) and the dynamics of the formation of
these gratings.
BIO
Dr. Karen K. Vardanyan is an
Assistant
Professor in the Dept. of Physics. He earned his BS in Physics
with specialization in Optics from Yerevan State University in July of
1993, MS in Material Sciences and Engineering from State Engineering
University of Armenia in July of 1995, PhD in Condensed Matter Physics
with specialization in Physics of Liquid Crystals from Institute of
Applied Problems of Physics (IAPP) of National Academy of Science of
Armenia (NASA) in May of 2000. His doctoral dissertation was devoted to
electro-optical properties of ferroelectric liquid crystals. In 1995
Dr. Vardanyan started his employment history as a Research
Assistant/Associate in IAPP-NASA. The research group, where Dr.
Vardanyan was a team member, o btained and reported a few new
ferroelectric liquid crystal systems with improved physical
characteristics in comparison with conventional nematic liquid crystals
that have been using for decades in many electro-optical applications.
From August of 1999 to February of 2001 Dr. Vardanyan worked as an
engineer in the Fiber Optics Division at Epygi-Labs LLC, Inc (US branch
in Yerevan, Armenia) performing research on application of liquid
crystals in WDM and DWDM telecommunication systems components. He also
taught mathematics and statistics at Moscow Business Academy (branch in
Yerevan, Armenia), where he was appointed as an Assistant Professor in
the Dept. of Math & Statistics. From February of 2001 to
February
of 2002 Dr. Vardanyan was a Postdoctoral Research Associate in the
Dept. of Electrical Engineering at Brown University, studying and
modeling the electro-optical properties of holographically formed
polymer dispersed liquid crystals (HPDLC) which are electrically
switchable Bragg gratings and have a number of applications in modern
optics and telecommunication. From June of 2002 to June of 2004 Dr.
Vardanyan was a Postdoctoral Teaching/Research Fellow in the Dept. of
Physics & Astronomy at Trinity University. During this time he
taught upper-division undergraduate courses and studied the formation
of travelling patterns in dye-doped nematic liquid crystals excited
with a laser beam. From August of 2004 to May of 2008 Dr. Vardanyan was
a Visiting Assistant Professor/Lecturer in the Dept. of Physics
&
Geology at UTPA. He taught general physics and physical science
undergraduate courses and did research in theoretical modeling of
pattern formations in liquid crystals. In August of 2008 Dr. Vardanyan
joined physics department faculty at Rutgers-Camden. Dr.
Vardanyan
has participated and presented his work in three international
scientific conferences. He is an author and co-author of 22
publications.
