Armin Ulrich

I hold a BS (Honors) in Math and Physics from New York University. I tend to look at things through a physics lens, with most of my work living between computation, math, and theory. I am currently doing research at NYU Courant on computational plasma physics.

Previously: Software Engineering Intern at Track Machines Connected (Linz, Austria), working on automated testing of applications.

Research

• Mar 2025 to present

  NYU Courant Plasma Physics Group (via the Courant SURE Program), working with Professor Alan Kaptanoglu on permanent-magnet stellarator design. I built a macromagnetic extension of greedy permanent-magnet optimization (GPMOmr) that accounts for finite permeability and demagnetization as part of the Simons Institute Collaboration on Hidden Symmetries. I am also working on VPML, an open source solver for the $1\mathrm{D}1\mathrm{V}$ Vlasov Poisson system with learned closure methods.

• Sep 2025 to Dec 2025

  Guided research in General Relativity at NYU Physics with Professor Gabe Perez Giz. I investigated gravitational waveforms from EMRIs using Numerical Kludge techniques, with a focus on phase accuracy and consistency near the separatrix.

  

• Jun 2024 to Dec 2024

  NYU Courant AI Predictive and Analytics Lab. I did a small project on low-latency sparse retrieval for physics corpora, including kernel approximations to attention matrices for scalability.
