Research interests: low-dimensional quantum materials and devices
Professor Adam Wei Tsen joined the Institute for Quantum Computing (IQC) and the Department of Chemistry as an assistant professor in 2016.
After receiving a BS in Electrical Engineering and Computer Sciences, as well as a BS in Engineering Physics at the University of California, Berkeley, he completed his PhD in Applied Physics at Cornell University under the guidance of Jiwoong Park.
Tsen then joined the Department of Physics at Columbia University as a postdoctoral associate with Abhay Pasupathy and Philip Kim, where he studied atomically thin quantum materials and incorporated them in nanoscale electronic devices.

Tsen's research focuses on the study of solid-state materials exhibiting rich quantum phenomena (superconductors, charge density waves, topological materials, etc.), applications of which may lead to significant breakthroughs in technology. Of particular interest are nanoscale systems where reduced phase space and increased correlations generally lead to enhanced quantum effects. Their low dimensionality also allows compatibility with current nanofabrication techniques, making them more suitable for future device integration. Tsen uses a combination of methods to probe the structural, optical, and transport properties of nanoscale quantum materials and further develops novel electronic and optoelectronic devices based on their unique behavior.
