Research Interests

Bioinorganic chemistry: Spectroscopic and biochemical studies to investigate how amino-acid identity and protein structure affects the ligand-discrimination mechanism utilized by gas-sensing heme proteins. Synthesis and characterization of metalloporphyrins with a series of amine ligands, with the goal of studying how the different amine ligands affect the metal’s binding affinity toward gas molecules. Joint project with Professor Engerer.

Chemical education: Development and analysis of innovative teaching and assessment practices to improve student learning and retention in STEM disciplines.
