Current Position

Post doctoral research associate (University of California, Berkeley). Working with Prof. Birgitta Whaley to develop and apply Quantum Monte Carlo methods to a wide variety of problems from studies of local superfluidity and coherence properties in weakly connected Bose gasses and fluids to the search for topological order in the ground state of lattice Hamiltonians.

Research Interests

Quantum coherence in mesoscopic systems: Strong interest in emergent properties of trapped / confined and disordered quantum many-body systems. Particularly interested in the interplay between interparticle correlations, system geometry and long range order including beyond-mean-field 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 lattice-like potentials are also of interest. Monte Carlo methods: Quantum Monte Carlo simulations of mesoscopic Bose and fermionic systems. Particularly interested in evaluation of pure estimates of the one-body density matrix and other correlation functions for strongly interacting systems in unique geometries. Also excited by and 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.
