Overview

About

BSc: University of Minnesota, Duluth, Minnesota

PhD: University of Utah, Salt Lake City, Utah (Prof. Peter J. Stang)


Research

Physical organic chemistry, new synthetic methods to carbon-rich molecules (e.g., cumulenes and polyynes, acenes and polycyclic aromatic hydrocarbons), relationships between chemical structure and molecular reactivity/properties; synthesis of compounds for applications as wires in single-molecule devices, solar cells, TFTs, singlet fission, as well as synthetic model compounds for the asphaltenes
