Cathy Drennan explains how she and her lab apply the principles of constructive / destructive interference, and other characteristics of light (including energy, frequency, and intensity) in their research using X-ray crystallography to determine the three-dimensional shape of proteins. Cathy’s lab captures “snapshots” of proteins in action with a focus on proteins with medical or energy/environment-related applications.
Cathy Drennan explains how her dyslexia, and other people’s low expectations of her because of it, have not prevented her from excelling in science and becoming a full professor at MIT. In fact, her “disability” has given her a unique set of visualization skills that allow her to better understand protein shapes and how they fit together.
