(Tom) Werkmeister

I am a Simons Junior Fellow at Columbia University and an upcoming Assistant Professor at TU Delft in the Department of Quantum Nanoscience, working on quantum transport in low-dimensional materials. Within condensed matter physics, I study quantum states of electrons, especially those exhibiting topological order, magnetism, or superconductivity. I study these states by creating 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 discovering better superconductors and stabilizing more robust topological order in new quantum materials. While my experiments enable direct probes of quantum physics, such as emergent anyons in two-dimensions, they also serve as practical tests of engineered quantum materials for applications, from topologically protected qubits for quantum computation to superconductor devices for quantum sensing.

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