Associate Professor, Chemical Physics Interdisciplinary Program
Director of Characterization Facility, Liquid Crystal Institute

O.D. Lavrentovich received his Ph.D. (1984) and Doctor of Science (1990) degrees in Physics and Mathematics from the Ukrainian Academy of Sciences. In 1992 he joined the Liquid Crystal Institute as a Senior Research Fellow and became an Adjunct Associate Professor of Physics. He has been an Associate Professor of Chemical Physics since 1994. Lavrentovich held visiting appointments at the University Paris-Sud, University P. et M. Curie, University Denis Diderot in France and the University of Cambridge, United Kingdom. He is Membership Officer of the International Liquid Crystal Society

Scientific interest include topological defects and patterns, surface- and light-induced phenomena; electrooptics of liquid crystals.
