Building high-quality HPC software for randomized numerical linear algebra.
Hi! I'm Aryaman, a graduate student at the School of Computation, Information and Technology at the Technische Universität München, where I work with Prof. Hartwig Anzt on high-performance-computing with a focus on Randomized Numerical Linear Algebra. I also collaborate closely with Prof. Michael Mahoney's group at Berkeley on RandNLA theory and algorithms.
Research interests
- Randomized numerical linear algebra — Subspace embeddings, least-squares, low-rank approximation, randomized preconditioners
- Mixed / low-precision GPU computing — FP16/BF16 kernels, stochastic and dithered rounding, deterministic rounding rules
- Numerical linear algebra — sparse direct/iterative solvers, Krylov methods
- Convex optimization and modeling systems — CVXPY, interior point methods, deep learning optimizers

Background
Before joining TUM, I spent a wonderful year in Berkeley doing research with Prof. Michael W. Mahoney's group, I worked closely with Oleg Balabanov on randomized preconditioners.
Before TUM and Berkeley, I spent 4 wonderful years at BITS-Pilani at the beautiful Hyderabad campus double majoring in Physics (masters) and Electrical Engineering (bachelor). During this time, I did multiple internships in industry and in academia — one at TCS Research where I was supervised by Prof. Mayank Baranwal (also adjunct faculty at IITB) where I worked on approximate second-order optimizers and one at Intel Labs (supervised by Sameh Gobriel) where I worked on scaling out the VDMS database and worked on a cool online optimization problem.
At BITS, I completed my first thesis (in physics) at the International Computer Science Institute, UC Berkeley (remotely), where I worked with Dr. Riley J. Murray on the Operator Relative Entropy Cone and made (further) technical contributions to the CVXPY codebase in the process. You can find my thesis here.
I completed my second thesis at CERN with funding from Princeton University's Department of Physics. I worked with Dr. Kilian Lieret on data-driven pipelines for charged-particle trajectory prediction, and concurrently with Dr. Henry Schreiner on scikit-build-core. My corresponding thesis is here.
I was also fortunate enough to do several REU's which allowed me to contribute to cutting edge open source software. I spent the summer of 2023 as a Research Engineer Fellow at Princeton University (under Princeton Research Computing), contributing to scikit-HEP with Dr. Henry Schreiner, and participated in GSoC-2023 with CVXPY. I spent the summer of 2022 writing open-source code for CVXPY under GSoC-2022
Far, far earlier, I worked with Prof. Snehanshu Saha (BITS Goa) and Soma S. Dhavala (Wadhwani AI) on quantile-regression methods for neural networks, with a pre-print here.
I read on my reading list and write (occasionally!) on my blog. The most up-to-date version of my CV is here.
