Armin Ulrich

I am a BS student in Mathematics and Physics at 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 AWS-hosted monitoring/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. A. Ulrich, M. Haberle, and A. A. Kaptanoglu. “Permanent magnet optimization of stellarators with coupling from finite permeability and demagnetization effects.” 2025. arXiv:2512.14997
• Sep 2025 to present

  Guided research in General Relativity at NYU Physics with Professor Gabe Perez Giz. I model 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.
