Ronald
Cohen
Ronald Cohen's primary focus is the study of materials through computational quantum physics to predict and understand the properties of materials. He studies materials under extreme conditions, such as high pressures and temperatures, and material behavior under strain and electric fields. His work applies to planetary physics, geophysics, and technology.
