// 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 represent very high-order tensors by a contracted network of low-order tensors, allowing one to make an exponential reduction in the parameters needed, while still maintaining accuracy. The prototypical application is the approximation of a many-body quantum wavefunction, but tensor networks are also useful for approximating transfer matrices of classical systems and weights of models used in machine learning.Download my CV
