My research group is interested in the behavior of materials under extreme conditions. We are well known for our spectroscopic work in high magnetic fields and pressures, under unusual chemical and photochemical activation, and at very small sizes where quantum confinement becomes apparent. Representative publications that illustrate the breadth and depth of our science program are given below.
