What happens when millions of electrons are crammed into a material with the thickness of a single atom? This question turns out to be one of the most complex that humans have ever dared to ask, and for decades theorists and experimentalists have been challenged to answer it. But how do we probe these tiny materials?

In our group, we develop new ways to measure the rich physics of low-dimensional materials like atomically-thin sheets and nanometer-wide nanotubes, and use these insights to develop new devices with novel functionality. We focus particularly on energy: how it flows through materials and what that tells us about emergent states of matter.
