I am a Ph.D. student in the Institute for Computational and Mathematical Engineering (ICME) at Stanford Univesity. I am advised by Biondo Biondi & András Vasy. I expect to graduate in 2022. I obtained a Masters from ICME in Computational Mathematics in 2017.
My current research interests include computational aspects of inverse problems, mathematical analysis, and quantum computation. See Research & Publications for more information on these projects and collaborators.
Jan 26, 2021My paper titled "A graph-based formalism for surface codes and twists", with Ted Yoder, is now on arXiv!
Aug 25, 2020My new paper titled "The index of invariace and its implications for a parameterized least squares problem", jointly with Léopold Cambier, is now available on arXiv! The paper substantially generalizes, and gives a much deeper explanation of the 1-dimensional subspace result by Hallman and Gu from 2018, available here. In addition, the paper contains lots of other new results, and also a new matrix manifold is characterized. As the title suggests, a quantity called the index of invariance plays a central and key role in the paper. The paper shows that for certain linear algebra problems, techniques from analysis and topology can often bring new and non-trivial insights!
