Research Interests

Our lab is interested in understanding the molecular mechanisms involved in how bacterial cells grow and divide. We have taken a combination of molecular genetics, biochemical and biophysical approaches in addressing two broad question in this area:

(i) Regulation of FtsZ, the tubulin-like bacterial protein, essential for division in most bacteria, and

(ii) Maintenance of bacterial cell envelope integrity in double-membraned bacterial cells.

Our work is currently supported by the National Science Foundation (NSF).
