Research Interest

1. Molecular Determinants for the Bioactivity of Dietary Compounds: my laboratory is examining the molecular mechanisms through which dietary compounds, specifically flavonoids, exert their effect to prevent cancer cell growth. Signaling pathways that regulate the cell cycle, apoptosis, and NF-kB activation are primary targets of interest. Drug-diet interaction is special focus of our research.

2. Anti-cancer cell and anti-microbial activities of natural compounds: we examine the potential bioactivity of natural compounds of diverse origin using cancer cells and common bacterial pathogens as targets.

3. Collaborative Research: a special cross-disciplinary project launched in collaboration with colleagues at the College of Engineering, Tuskegee University, to derivatize single walled carbon nanotubes (SWCNT) and to coat them with anti-cancer or anti-microbial compounds that can later be used in various applications in vivo or in the environment.
