Levine tries to understand what makes chemical reactions go. To do so he often seeks to view the reaction on the most highly resolved level, that of the actual molecules undergoing the change. As the starting materials evolve into the products, how do the atoms move, what energetic constraints operate and are there any steric requirements. Levine is a theorist but he does attempts to find out what are the concerns of his experimental colleagues. Currently the systems he studies are larger than before and he is able to explore further away from equilibrium. One line of such activity is chemistry under extreme conditions, work for which he was selected for the McCoy Award of the UCLA Department of Chemistry and Biochemistry. His most recent book, Molecular Reaction Dynamics (Cambridge University Press, 2005) provides more details. Recently he is also concerned with processes that occur simultaneously on several electronic states (so called, the breakdown of the Born-Oppenheimer approximation). Dr. Levine's research methods include molecular dynamics simulations and quantum mechanical methods. Often he seeks a more compact description. For this, methodologies based on information theory and on algebraic quantum mechanics are useful. In particular, they provide methods of data reduction (e.g., surprisal analysis) that can also be used in a predictive model. He prefers models that emphasize key aspects of the problem and allow for a simple conceptual picture of the dynamics as much as exact numerical simulations. He also indulges in examining more long range issues such as his recent activities in making a single molecule act as a computing machine. |
