Dr. Pierce studies the fungus, Candida albicans, which is capable of causing disease, particularly in immunocompromised patients. Candida infections are the fourth most common nosocomial, or hospital-acquired, infection. The seriousness of these infections is heightened with unacceptably high mortality and the limited number of antifungal drugs. Dr. Pierce’s research has been focused on understanding the role of biofilm formation and filamentation in C. albicans infections and the development of novel agents targeting these virulence factors associated with infection.

Dr. Pierce’s current research interests lie in identifying and subsequently characterizing the activity of anti-biofilm and anti-filamentation compounds, with emphasis on minimizing the potential to induce resistance. The main components of his research are: (i) Identify anti-virulence compounds from commercially available small molecule libraries. These libraries represent a promising arsenal of potential antifungal candidates that can be screened for inhibition of biofilm formation and filamentation. (ii) Characterize the mechanism(-s) of action of the identified inhibitors of biofilm formation and filamentation. These studies include the effects of compounds on global mechanisms of biofilm formation (adhesion, proliferation, and maturation), drug combination studies, development of resistance assays, cytotoxicity assays, and identification of the molecular targets.

The environment of Dr. Pierce’s laboratory at UIW is focused on training and developing undergraduate students as independent researchers. Dr. Pierce has mentored a number of students in the lab. Students in the lab have presented their work at UIW Research Week, as well as, regional and state conferences. Mentoring students, whether in the classroom, research lab or at scientific conferences, is one of Dr. Pierce’s passions.
