Research Interests

My research interests, albeit broad, aim to develop more accurate diagnostic tests for infections that are under-/misdiagnosed. I am especially interested in understanding the complexity of biofilms as it pertains to treatment options, including pulmonary nontuberculous mycobacteria (NTM) infections. Antibiotic susceptibility testing typically is performed on planktonically grown microorganisms, though many infections involve biofilms. While an antibiotic may test susceptible, it may not clear the infectious microorganism due to the inability to penetrate the biofilm. In addition to investigating ways to improve treatment of biofilm-associated infections, I plan to continue studying other mechanisms to identify antibiotic resistance beyond phenotypic characteristics, including novel molecular techniques.
