Research Interests

I am broadly interested in condensed-matter physics, but particularly in the way that electrons behave when they are subjected to extreme conditions such as ultra-low temperatures and high magnetic fields. Under such conditions, electrons can display striking collective quantum behavior such as superconductivity, fractionalization of charge, and crystallization. Currently, we are investigating phenomena such as these by studying:
  • The physics of low-dimensional structures, especially “van der Waals heterostructures” of two-dimensional crystals (the most familiar of which is graphene), which we build in the lab and then fashion into mesoscopic devices using nanofabrication techniques, and
  • A variety of methods for probing these mesoscopic devices, such as electronic transport, capacitance, tunneling spectroscopy, and shot noise.
