My research group uses computational modeling to design materials with medical and industrial applications. We are able to answer questions that cannot be answered by experiment alone. We aim to explain the properties of different materials and get insights into the reasons for their unique behavior. Then we use this knowledge to design new materials with enhanced and desired characteristics to guide their experimental synthesis, and ultimately increase their practical applications.

Our current research focuses on computational modeling of fluorescent dyes with exciting applications such as biological labels, imaging agents, ion sensors, and sensitizers for the photodynamic therapy (PDT) of cancers. Borondipyrromethene (BODIPY) is a class of fluorescent dyes that has low cytotoxicity and high cell membrane permeability. These dyes absorb and emit energy in the visible and near-infrared region of the spectrum, and have excellent photophysical and optoelectronic properties. We examine different structural modifications of these molecules with the aim of increasing their stability and solubility, as well as to finely tune their photophysical properties.

We work in in collaboration with  the group of Dr. M. Graca H. Vicente from Louisiana State University who performs the experimental synthesis of BODIPYs. 

We have an active grant through the National Science Foundation (NSF). The grant allows for my research students to travel to conferences, as well as to receive small stipends for performing research during the semester.

The Department of Chemistry and Fermentation Sciences supports our research students during the summer. We began participating in  ChemAppalooza  in Summer 2023.
