I was born and raised in New York City, but decided to travel away from home for my education. I received my B.A. in Biology from Grinnell College in Iowa. As a college student I was first exposed to laboratory research and found that I enjoyed the hands-on aspect of doing science. I decided to continue my science education and went to the University of Wisconsin-Madison for graduate school, where I earned a PhD in Cellular and Molecular Biology.

Upon returning from the Midwest, I spent several years as a Research Fellow at Albert Einstein College of Medicine in the Bronx. At Einstein I began to study the biology of melanized fungi, the subject of my current research.

Research

My research interests focus on fundamental questions in the biology of melanotic fungi. Melanins are a family of related compounds that have remarkable physical properties. They are found throughout the natural world and have diverse functions ranging from camouflage and display, to protection from ultraviolet radiation and enhancement of virulence in microbes.

Melanins are found in many fungi, including known pathogens, and play important roles in both pathogenesis and environmental survival. I study melanization in Cryptococcus neoformans, a fungal pathogen that is a relatively frequent cause of disease in immunocompromised individuals.
