My research program is in the field of experimental condensed matter physics with particular focus on the magnetism and electronic properties of materials, using thermodynamic, electrical and thermal transport, cantilever-based magnetometry and Raman/IR spectroscopy. These physical quantities are investigated under extreme conditions such as very low temperature, high DC and pulsed magnetic field, high hydrostatic pressure and sometimes nanoscale spatial dimension. Specific experimental expertise includes thermoelectric phenomena, electrical and thermal conductions particularly in the presence of magnetic ordering and in low dimensional systems near the phase boundary. My group also synthesizes high quality single crystalline semimetals and magnetic compounds.
