Welcome to the Fast Lab. We are guided by a broad curiosity about how enzymes work and how we can manipulate their functions. We study the chemistry behind how these proteins accelerate chemical reactions that are important for biological processes and use this information to develop small molecules to regulate the enzyme’s function, to design variant enzymes with altered functions or properties, or to design chemical probes to study the activity of enzymes within living cells. Inhibitors that rely on covalent bond formation as part of their mechanism are of particular interest. We choose to study enzymes that are suitable targets for new drugs, so our work serves as an early step in the development of novel therapeutics. My teaching involves undergraduate students, graduate students, postdoctoral researchers and professional pharmacy students in class and in the laboratory. Our current research projects are in the areas of infectious disease, cancer, and cardiovascular / pulmonary health.
