Dr. Sein is Assistant Professor of Chemistry in the Department of Chemical and Physical Sciences, Cedar Crest College, Allentown, PA. Born and raised in Philadelphia, he received his B.S. in chemistry from Charter Oak State College in 1996, M.A. in chemistry from Temple University in 1998, and Ph.D. in inorganic /physical chemistry (also from Temple) in 2000. He completed post-doctoral terms at Thomas Jefferson University and the University of Pennsylvania in computational biophysics.  He has been an invited speaker at the Technical University of Eindhoven, the Netherlands; Agricultural University of Wroclaw, Poland; and Princeton University in the United States.
After having taught at Temple University, Philadelphia University, Cabrini College, and Montgomery County Community College, Dr. Sein joined the faculty at Cedar Crest College in the fall of 2005.  He teaches courses in inorganic chemistry, and the quantum mechanics (Physical Chemistry II) course. He developed a new inorganic synthesis laboratory in 2005, and wrote an inorganic chemistry textbook emphasizing concepts from group theory. His research interests include conducting polymers, computational chemistry, and heterogeneous catalysis. He is co-author on 28 publications in such journals as the Journal of Physical Chemistry, Environemtal Science and Technology, and Synthetic Metals.
