John M. Galbraith is a Computational Chemist with more than 30 years’ experience in molecular orbital and valence bond theory calculations of small molecules. He has 20+ years teaching undergraduate courses in Computational, Physical, Inorganic, and General Chemistry. He is currently an Associate Professor of Chemistry at the Department of Chemistry, Biochemistry, and Physics, Marist University, USA. T. Daniel Crawford is University Distinguished Professor of Chemistry at Virginia Tech, USA and the Director of the Molecular Sciences Software Institute in Blacksburg, Virginia. He received his bachelor's degree in 1992 from Duke University and his Ph.D. in 1996 from the University of Georgia, working with Prof. Fritz Schaefer. His research focuses on quantum chemical models of molecular properties, particularly the spectroscopic responses of chiral compounds. He is a Fellow of the American Chemical Society and the winner of 2010 Dirac Medal of the World Association of Theoretical and Computational Chemists.
