Prior to joining Yale-NUS College, Professor Steven Lynn Bernasek was a Professor of Chemistry at Princeton University. He received his undergraduate degree from Kansas State University and his PhD from the University of California, Berkeley. An experimental physical chemist, Prof Bernasek’s research interests are in the areas of surface chemistry and chemical physics. Prof Bernasek’s research focuses on the application of gas phase molecular reaction dynamics tools to the study of heterogeneous reactions and he has published over 200 papers in journals such as Journal of Chemical Physics, Journal of Physical Chemistry, Journal of the American Chemical Society and Surface Science. A fellow of the American Association for the Advancement of Science, he has been a Research Fellow of the Alexander von Humboldt Foundation and has received the American Chemical Society Arthur W. Adamson Award for Distinguished Service in the Advancement of Surface Chemistry.
