Diana Roe, Ph.D.
My research focuses on the problem of molecular recognition, or how two molecules "recognize" and bind to each other. This provides the fundamental basis for understanding important biological processes such as how a protein binds to its receptor, how an antibody interacts with and antigen, or how a drug molecule interacts with its target protein. I work in "structure-based" design, meaning I start with a three dimensional structure of two molecules, and use molecular mechanics/dynamics and docking codes as tools to predict their interactions.

I both develop and apply new software tools for structure based molecular design. I developed the BUILDER program for de novo drug design, and CombiBUILD for applying structure-based design to combinatorial chemistry libraries. My current applications are in the area of protein toxins. I'm searching for small molecules that block the function of toxins, and thus are potential lead drug compounds (antitoxins). I'm also looking for small molecules that bind selectively to a protein toxin that can be useful for affinity-based sensors.
