Adam Wei Tsen

Wei Tsen's research focuses on the study of low-dimensional materials that exhibit exotic quantum phenomena, and their integration into novel electronic devices. 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.

In 2016, he joined the University of Waterloo's Department of Chemistry and the Institute for Quantum Computing. He is continuing to explore these materials and develop novel quantum devices based on their exotic properties.
