I like building machines and have spent most of my career developing technologies for scientific instrumentation and performing new kinds of measurements on condensed matter systems. I have investigated topological phases, exotic magnets, and superconductors, and I enjoy thinking about ways in which interaction-driven electronic phases can be used to support new technologies. I am currently working with transition metal dichalcogenides in Professors Jie Shan and Kin Fai Mak’s laboratory at Cornell University, supported by a Kavli Institute at Cornell postdoctoral fellowship.

News

Media appearances and commentary on our work.

Berry does both, Yonglong Xie , Professor Yonglong Xie of Rice University wrote an excellent summary and explanation of our recent work studying spin Hall torques in magnetic Chern insulators.
Two paths to intrinsic quantization, Joshua P. Wakefield and Joseph G. Checkelsky , Joshua Wakefield and Joe Checkelsky compare and contrast our work (and that of David Goldhaber-Gordon’s lab) on BN-aligned graphene homobilayers to that of Yuanbo Zhang on manganese bismuth telluride monolayers.
