My research focuses on neutrinos, radiation detection, photosensors, nuclear signatures, international safeguards, and applications of deep learning. As a member of the nEXO collaboration, I contribute to the research and development of a next-generation underground experiment designed to explore the fundamental nature of the neutrino. In my lab, we study the detection mechanisms, hardware design, and data analysis of vacuum ultraviolet light signals in liquid xenon to pursue one of the most significant unanswered questions in physics today: Is the neutrino its own antiparticle?

Current Courses

Fall Semester 2025

Introductory Physics of Living Systems I/Lab

PHYS 107

An introduction to physics designed for students majoring in life sciences and/or interested in pre-health studies. Topics include geometrical optics, Newtonian mechanics, acoustics, fluids and thermal physics. Class meetings integrate group-based laboratory investigations, simulations and problem s…

Energy, Matter, and Motion

PHYS 109

A calculus-based introduction to physics for students interested in the physical sciences. Starting from the concept of energy, the course develops mechanics and thermodynamics with a focus on conservation laws for mass, momentum, and energy. Students examine the atomic nature of matter and its impl…

Senior Thesis

PHYS 457

An independent study program for students working on a research problem in a field of interest, culminating in the writing of a senior thesis. Students register for PHYS 457 in the fall semester. Majors writing an honors thesis register for both PHYS 457 and 458.

Winter Semester 2026

Introductory Physics of Living Systems II/Lab

PHYS 108

A continuation of PHYS 107, designed for students majoring in life science and/or interested in pre-health studies. Topics include wave optics, electricity and magnetism, quantum and nuclear physics. Class meetings integrate group-based laboratory investigations, simulations and problem solving. Pre…

Electricity and Magnetism

PHYS 222

A detailed study of the basic concepts and fundamental experiments of electromagnetism. The development proceeds historically, culminating with Maxwell's equations. Topics include the electric and magnetic fields produced by charge and current distributions, forces and torques on such distributions …
