(Tom) Werkmeister

I am a Simons Junior Fellow and Postdoctoral Research Fellow in Applied Physics at Columbia University, working on the physics of low-dimensional materials. Within condensed matter physics, I focus on quantum states of electrons, especially those exhibiting topological order, magnetism, or superconductivity. I study these states by creating and measuring quantum coherent devices made from novel materials like graphene. Some of my recent devices have been fractional quantum Hall edge state interferometers and Josephson junction interferometers. More generally, I am interested in synthesizing better superconductors and stabilizing topological phases at higher temperatures using new materials. These material improvements are critical for emerging technologies, from topologically protected qubits for quantum computation to powerful magnets for magnetic levitation, magnetic resonance imaging, and nuclear fusion.

I received my Ph.D. in Applied Physics from Harvard University in 2025 and previously my B.S. from the University of Pittsburgh.
