Research Interests

Design, discovery, growth and characterization of new and exotic materials with electronic and/or magnetic phase transitions are the primary focus of my research group. Compounds are usually prepared in single crystal form, so the measurement of the anisotropic, temperature and applied magnetic field dependent magnetization, specific heat, electrical resistivity, and thermoelectric power are our primary characterization measurements.
