I am an assistant professor at the Department of Physics and the Virginia Tech Center for Quantum Information Science and Engineering.
I'm broadly interested in quantum error correction, quantum gravity, and quantum foundations. Ideally, I'd like to understand the nature of time and space, and why quantum looks the way it is. Those are too hard, so we need to take a break every now and then by thinking about useful problems, like how to build a quantum computer.
I jest, they are both exciting and are difficult for different reasons.
Before joining VT, I spent a happy year as a postdoc/visiting associate at IQIM, Caltech. Prior to that, I was a Hartree fellow at QuICS, the University of Maryland. I am extremely grateful for all my awesome postdoc supervisors Prof. Andrew Childs, Prof. Brian Swingle, and Prof. John Preskill. It was a lot of fun learning from them and from everyone around me.Â
I received my PhD from Caltech under the guidance of Prof. Sean M. Carroll (not to be confused with Sean B. Carroll, the famous biologist) whose view of quantum mechanics has continued to shape the way I think about the universe. You probably have heard of him in the popular science sphere; but in case you haven't, you should definitely check out his books and podcast.
I received my B.Sc. in combined honours (yes, with a "u" ;) ) math and physics from the University of British Columbia. I was an undergrad minion in Prof. Jess Brewer's lab and later a slightly older minion in the T2K collaboration. I had a lot of fun working on neutrino and nuclear physics experiments, but I had to be careful so that Prof. Hiro Tanaka and Prof. Mike Wilking's offices don't glow in the dark. Since I also wanted to try theory, Prof. Ariel Zhitnitsky kindly took me in. We worked on topics related to the strong CP problem and our collaboration continued for a few more years after my graduation.
