We are a theoretical chemistry research group at Temple University Dept of Chemistry dedicated to developing and applying advanced electronic-structure and dynamical methods to investigate nonadiabatic phenomena in photon- and electron-driven reactions, with the goal of better understanding radiation damage to DNA.
Most chemical processes follow the Born-Oppenheimer (adiabatic) approximation, in which the nuclei move on a single potential energy surface. However there are important processes where this approximation breaks down. These nonadiabatic events play an important role in essential processes in nature such as photosynthesis, vision, charge transfer and photochemistry. Focus areas are: Photophysics and photochemistry of biologically relevant systems, such as DNA/RNA; Theoretical description of conical intersections and excited states; Understanding laser control of molecular dynamics.
We are looking for passionate new PhD students, Postdocs, and Master students to join the team (more info) !
