Research Description
All bacteria have a shape and, for the most part, this shape is determined by a rigid casing known as the peptidoglycan cell wall. My research focuses on understanding how cells produce and maintain the peptidoglycan layer. This includes studying cytoskeletal proteins (i.e. FtsZ and MreB), peptidoglycan modifying enzymes, and other morphological mechanisms.
