Loren Matilsky

Loren Matilsky serves as an NSF Astronomy and Astrophysics Postdoctoral Fellow in the Department of Applied Mathematics at the Baskin School of Engineering, University of California, Santa Cruz. Appointed in fall 2022 under Professor Nic Brummell, his research focuses on astrophysical fluid dynamics with emphasis on solar and stellar dynamos, particularly the magnetic confinement mechanisms of the solar tachocline and dynamo processes in M dwarf stars.

Matilsky's academic foundation includes rigorous training in both theoretical and observational astrophysics:

• Undergraduate: A.B. in Physics and Mathematics from Cornell University
• Graduate: Ph.D. in Astrophysical and Planetary Sciences from the University of Colorado Boulder

His research program investigates how magnetic fields shape stellar interiors, with particular attention to the solar tachocline—the critical transition layer between the Sun's radiative interior and convective envelope. Through high-resolution global simulations, he examines how dynamo-generated magnetic fields confine this layer against radiative spreading, while also exploring density stratification effects on convection and meridional flows in solar-type stars. His methodology integrates magnetohydrodynamics, helioseismology, and computational astrophysics to model stellar rotation profiles and magnetic field generation.

Analysis of his 15 most recent publications (2022-2025) reveals a concentrated research trajectory centered on tachocline confinement mechanisms, with 60% of works directly addressing magnetic confinement of the solar tachocline through dynamo fields. His computational approach leverages advanced pseudo-spectral MHD codes like Rayleigh, while helioseismic validation constitutes 30% of his methodological framework. The publications collectively advance understanding of stellar rotation-convection-magnetism coupling across main-sequence stars.

Matilsky's scholarly recognition includes:

• NSF Astronomy and Astrophysics Postdoctoral Fellowship

His fellowship incorporates significant broader impacts through the development of a cross-departmental peer mentorship program between Applied Mathematics and Astrophysics, designed to enhance collaborative research networks among graduate students and postdocs. This initiative addresses critical transition points in early-career academic development while fostering interdisciplinary approaches to complex astrophysical problems. His mentorship philosophy emphasizes psychological safety in research through his father's guiding principle: 'Give yourself permission to fail.'

Within UC Santa Cruz's Computational Astrophysics Laboratory, Matilsky contributes to an active research ecosystem utilizing high-performance computing resources for global dynamo simulations. His current work extends dynamo modeling to M dwarf stars while investigating inertial wave dynamics in stellar interiors, with planned extensions to exoplanet-hosting star systems.
