profile


I joined IBM in 2015 as a research staff member in the experimental quantum computing group. Prior to this I was a postdoctoral scholar at the University of Chicago in Prof. David Schuster's lab from January 2013 to December 2014 researching circuit quantum electrodynamics. In July 2012 I received my PhD from the University of Illinois at Urbana‐Champaign under the supervision of Prof. Brian DeMarco (co‐supervised with Prof. Joseph Thywissen at the University of Toronto). The main topic of my thesis work was to utilize ultracold atoms in optical lattices to investigate properties of the Bose and Fermi Hubbard models. In particular, at the University of Illinois I performed experiments with a gas of Rb‐87 atoms (a boson) loaded into a 3D optical lattice. This system realizes the physics of the Bose‐Hubbard model, which is a paradigm for strongly correlated lattice physics. One highlight of this work was implementing a fully three‐dimensional spin‐dependent optical lattice which allowed experiments with a lattice‐trapped gas in contact with a gas that does not experience a lattice potential. Part of my thesis work was performed at the University of Toronto (under the supervision of Prof. Joseph Thywissen) where we designed and developed a K‐40 (fermionic) experiment with the goal of resolving individual sites of a 2D lattice using in‐situ fluorescence imaging. K‐40 in a 2D optical lattice realizes the 2D Fermi‐Hubbard model, which is a candidate model for describing the main features of the high temperature superconducting cuprates.
