Research Interests:
The goal of our research is to provide tools for and insights into two technologically important problems: energy conversion (for example, solar cells and lithium batteries) and drug development. One of our strategies is to utilize the unique properties of organofluorine compounds as tools for improving materials properties and function. You will find more information about our research on our group webpage. We welcome talent at all levels--undergraduates, graduates, postdocs, and visiting scholars--to join us in solving energy and medicinal problems faced by our society. Our research program provides comprehensive training for students in the fields of organic, fluorine, and materials chemistry. Students working in our group will gain practical experience in synthesis, separation, and characterization of various materials ranging from small organic molecules to metal nanoparticles. We value students’ professional development and aim to prepare them for future success.
