Research Interests

As an MD/PhD candidate, I am broadly interested in the regulation of cellular processes at a molecular level that ultimately leads to clinical outcomes. In the past, have made meaningful contributions to understanding howÌýBordetella pertussis, the causative agent of whooping cough, regulates its genes to survive in different environments, enabling its persistence and transmission from one host to another. I have also dissected the role of eukaryotic Initiation Factor 3 (eIF3), a protein that has been implicated in the development and progression of various human cancers, in mediating the initiation step of protein synthesis.

As a graduate student in the Fries Lab, I am studying how Cryptococcus neoformans (Cn), an opportunistic yeast that causes fungal meningoencephalitis, regulates its metabolic processes to promote antifungal resistance. Furthermore, I am investigating how itaconic acid (IA), an immunomodulatory metabolite produced within the TCA cycle, can affect Cn:macrophage interaction to alter the outcome of cryptococcal infection.
