My research interests have focused on developing instrumentation and techniques that employ the polarization properties of synchrotron radiation to probe magnetic systems. I have been particularly interested in applying these novel capabilities to probe the magnetic behavior of rare earth - transition metal compounds in extreme environments, such as high-magnetic and electric fields, high-pressures, and low temperatures.
