About

I am a graduate student in Physics at The Ohio State University and a member of the Center for Cosmology and AstroParticle Physics (CCAPP), where I am being advised by Dr. Tyler Gorda.

My current research is centered on quantum field theory at finite temperature and density, with particular emphasis on perturbative descriptions of hot and dense matter. I am interested in the thermodynamics of relativistic gauge theories, scale separation and resummation, and in extending weak-coupling methods across physically relevant regimes of temperature and chemical potential.

My previous work has involved stochastic interacting systems, nonequilibrium statistical mechanics, and spectral questions associated with random tensors.

I am broadly interested in analytical problems in statistical physics, particularly where field-theoretic, perturbative, many-body, and asymptotic methods intersect.

Hot and dense quark matter

Thermodynamics of relativistic matter at nonzero temperature and chemical potential, including problems motivated by dense QCD and the physics of strongly interacting matter.

Stochastic processes and nonequilibrium systems

Interacting stochastic systems, driven dynamics, transport, and collective behavior in low-dimensional and geometrically constrained systems.

Statistical mechanics

Analytical approaches to many-body statistical physics, emergent behavior, interacting particle systems, and systems with nontrivial geometry.

Random tensors

Eigenvalue and eigenvector distributions of higher-order random tensors and related questions at the interface of mathematical and statistical physics.
