About
I am currently a research scientist at the IBM Thomas J. Watson Research Center at Yorktown Heights, NY. Previously, I completed my PhD in Physics at the University of California, Berkeley supervised by Prof. Michael Zaletel and Prof. Irfan Siddiqi.
Research
I am interested in theoretical and experimental aspects of novel quantum devices, gates and error-correction, particularly in superconducting circuits. I am also interested in topological phases of matter and using and developing classical numerical techniques, such as tensor network methods, for studying them.
