Research:
 Quantum Monte Carlo: Explicit many body simulations of mesoscopic Bose and fermionic systems. Particularly interested in evaluation of pure estimates of the onebody density matrix and other correlation functions for strongly interacting systems in unique geometries. Also interested in the development and application of Quantum Monte Carlo methods from a purely technical standpoint including synergies with other stochastic methods as applied to problems such as pattern recognition and inverse optimization.
 Quantum coherence in mesoscopic systems: Strong interest in emergent properties of trapped / confined and disordered quantum manybody systems. Particularly interested in the interplay between interparticle correlations, system geometry and long range order including beyondmeanfield effects such as condensate fragmentation and other collective effects which are strongly modulated by synergies between interparticle interactions and finite size effects. Systems with persistent flow states such as superconducting quantum interference devices and rotating condensates as well as transport properties of superfluids in latticelike potentials are also of interest.
