// About me
I am a research scientist at the
Center for Computational Quantum Physics (CCQ) where I develop
and apply tensor network computational methods, primarily for quantum many-body systems.
[See my notes on matrix product states and DMRG.]
Tensor networks are a technique to compress exponentially large collections of parameters (e.g. wavefunction amplitudes or elements of matrices acting on tensor product spaces) by replacing them with a linear-size collection of hidden or virtual parameters contained in a contracted network of low-order tensors.Download my CV
Research Scientist — Flatiron Institute
Research Scientist — UC Irvine
Feb 2016-Aug 2017
- Scalable "sliced basis" approach for applying DMRG to quantum chemistry
- Proposed a machine learning framework based on powerful tensor network techniques developed in physics. Video and talk slides.
Postdoctoral Researcher — Perimeter Institute for Theoretical Physics
- Showed an isotropic, nearest-neighbor 2d parafermion lattice model hosts a non-trivial phase supporting Fibonacci anyons
- Performed highly cited calculations of universal entanglement terms in critical systems arising from sharp corners
- Significantly expanded the user base of the ITensor library and developed an ambitious new version 2.0 design
Postdoctoral Researcher — UC Irvine
Groups of Steven R. White and Kieron Burke
- Discovered a method for parallelizing the density matrix renormalization group in real space.
- Co-developed an open source library for tensor product wavefunction algorithms. Website: http://itensor.org/.
Graduate Student Researcher — UC Santa Barbara
Advisor: Leon Balents
- Applied a variety of analytical methods (bosonization, mean-field, spin wave, high temperature series, Monte Carlo) to study frustrated magnets.
- Collaborated with Steven R. White on a new method for simulating finite temperature quantum systems (the METTS algorithm).
