Research Interest

Our research focuses on the creation, design, and combined spectroscopic and atomic-scale visualization of exotic states in low-dimensional quantum materials. Our fundamental goal is to push our understanding of the origins of emergent behavior in quantum materials by custom designing novel quantum states using a host of innovative in situ design techniques, including nanoscale patterning and physical strain. Our approach to probe the novel physics in these resultant systems combines real- and momentum-space spectroscopic tools, including atomically-resolved scanned probe microscopy (SPM) and angle-resolved photoemission spectroscopy (ARPES). Our group is additionally involved in the custom development of novel low-temperature, high-magnetic field scanning probe systems.
