Development of antifungal compounds: A major focus of our laboratory involve collaborative projects with Dr. Suresh Kumar and Dr. Matt McIntosh in the Department of Chemistry and Biochemistry, and Dr. Ines Pinto in the Department of Biological Sciences to identify compounds or peptides that display antifungal activity for potential use in the treatment of fungal infections in humans.  In addition, we explore the mechanism(s) of action of these antifungal agents.

The role of the CCAAT-binding factor in Candida albicans pathogenesis.  The main focus of this research is to determine the role of the CCAAT-binding factor in Candida albicans pathogenesis.  In particular, we are interested in how this transcription factor regulates genes involved in iron uptake/utilization and genes involved in the oxidative stress response.

Understanding the impact of graphene-based nanomaterials on human health.  The main focus of this research is to evaluate the toxicity of various graphene-based nanomaterials to eukaryotic cells using Saccharomyces cerevisiae as model single-celled eukaryote.
