Postdoctoral scholar in computational mathematics

Lawrence Berkeley National Laboratory


I am a Postdoctoral researcher working in the Scalable Solvers Group at Lawrence Berkeley National Laboratory on matrix and tensor decomposition techniques for quantum computing.

I obtained my PhD in Computer Science from KU Leuven where I worked on pole swapping methods for eigenvalue problems.

Recent Publications

Approximate Quantum Circuit Synthesis using Block-Encodings

An approximate quantum circuit synthesis technique that combines circuits for smaller matrices into quantum circuits of larger operators.

On pole-swapping algorithms for the eigenvalue problem

This article studies a convergence theory applicable to all pole-swapping methods. It proposes a backward stable algorithm to compute a pole swap in finite precision.
