Leif obtained his Ph.D. from Ohio State University in 2011 where he worked with John M. Herbert and was a presidential fellow. His doctoral work included development of mixed quantum classical dynamical methods applied to the aqueous electron and development of fragment based ab-initio methods utilizing Symmetry Adapted Perturbation Theory. Following his doctoral work Leif studied non-adiabatic dynamics with John C. Tully at Yale University. Since joining Schrodinger in 2013 as a scientist Leif has focused on developing novel automation methodologies for transition state finding and reactivity predictions. More recently he has worked on expanding the domain of applicability of transferable neural network potential energy surfaces to include applications to ionic systems, intermolecular interactions and reactive regions of the potential energy surface.
