Research Interests

My research focuses on the synthesis and discovery, characterization, and optimization of novel quantum materials (e.g. Weyl semimetals, superconductors, antiferro- and ferromagnets, magnetocaloric and thermoelectric materials) in a single crystalline form. My interest is in the exotic electronic and quantum states of matter that are realized in quantum materials and can be tuned with chemical substitution, magnetic field, or application of pressure.
