Research Interests

My interests revolve around the investigation of viral assembly and the description of biological motors at the molecular level. Both historically and experimentally, bacteriophages provide a perfect system to address both of these issues. My current focus is on the study of bacteriophage phi29 DNA packaging. A molecular motor assembles transiently to the phi29 prohead capsid and packages DNA to near crystalline density, powered by ATP hydrolysis.

To fully describe the mechanism of this motor, and gain understanding about molecular motors in general, I am part of a large interdisciplinary group comprised of specialists in structural biology, biophysics, molecular genetics and biochemistry. As a phage biochemist, my role is to translate the basic components of phi29 packaging from our robust in vitro packaging system into hands of specialist who can address the questions of interest our work has generated, as well as develop new approaches meant to interrogate the packaging mechanism.
