Biography

Alp Sipahigil is the Ping & Amy Chao Family Assistant Professor of Electrical Engineering and Computer Sciences at the University of California, Berkeley. He has joint appointments as a Faculty Scientist at the Materials Sciences Division at Lawrence Berkeley National Laboratory and a supporting appointment at UC Berkeley Physics.

He leads the Berkeley Quantum Devices Group which focuses on solid-state device research to advance quantum computation, communication and sensing. His group studies a wide range of physical systems including superconducting quantum circuits, color centers, integrated photonics and phononics.

Prior to joining Berkeley in 2021, he was an Institute for Quantum Information and Matter postdoctoral scholar at Caltech. He received his Ph.D. in Physics from Harvard University in 2017 and his B.S. degrees in Physics and Electrical Engineering from Bogazici University in 2010.
