Exploring The Molecular World with X-Ray Diffraction


Diffraction, constructive and destructive interference, photon energy versus photon intensity

Featured Scientist

Cathy 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.
