My research utilizes tools of experimental physical chemistry to investigate metal ion-molecule interactions, characterize the proton solvation and conduction mechanisms in ionic liquid solutions, and protein stability in aqueous ionic liquids.

My lab has four main research projects underway:

Characterizing the solvation of protons in ionic liquids and the proton transportation mechanisms in acidic ionic liquid solutions.

Understanding the behavior of proteins and antibiotics in aqueous ionic liquid solutions.

Evaluating competitive metal ion chelation by small molecules in the presence of peptides.

Synthesizing and evaluating different hydrogen-generating electrocatalysts.
