Organic Chemistry, Advanced Organic Chemistry, Electrochemistry, Spectroscopic Analysis

My research is focused on the synthesis of two classes of molecules: functional organic materials with special optical and electronic properties, and biologically relevant small organic molecules. The aim of my research is to provide tools for, and insights into two technologically important problems: energy conversion and drug development. One of our strategies is to utilize the unique properties of organofluorine compounds as a toolbox for organic synthesis and to prepare probes of biological function. A unique element to my research will be the development and utilization of new fluoroorganic chemistry. The research program provides training for students in the fields of synthetic organic chemistry, fluorine chemistry, optical and electronic materials chemistry, and bioorganic chemistry. A student/postdoc working in my research group will gain practical experience in multi-step synthesis, modern separation and characterization techniques, air-sensitive techniques, modern electrochemical techniques including digital simulation and spectroelectrochemistry, and computational methods (e.g., ab initio, DFT, MP2).
