I am an experimental condensed matter physicist. My primary research goals are directed towards discovery and understanding of novel collective behaviors in quantum materials. Particular examples include unconventional superconductivity emerging near a quantum critical point, and exotic Weyl/Dirac excitations in semimetals with strong spin-orbit coupling. My lab will focus on crystal growth, thermodynamic and magnetic measurements, and novel experimental techniques that utilize strain to probe and manipulate the symmetry properties of materials.
