About Me

I am an MIT Physics Ph.D. student and NSF Graduate Research Fellow working at the intersection of experimental particle physics, detector instrumentation, and hardware engineering. I completed concurrent A.B. and A.M. degrees at Harvard in 2026: an A.B. in physics and mechanical engineering, with a secondary field in astrophysics, and an A.M. in physics.

At MIT, I work on detector instrumentation and signal processing for the Deep Underground Neutrino Experiment (DUNE), developing physics-based reconstruction and inference methods for liquid-argon detector signals, detector simulations, and FPGA-oriented approaches to low-latency processing.

Previously, I developed calibration hardware and simulations for IceCube optical modules, led the Harvard Undergraduate CubeSat (HUCSat) through spacecraft integration and delivery as Chief Engineer, investigated time synchronization for PNT applications at the U.S. Army DEVCOM C5ISR Center, and built precision optical and THz instrumentation at Harvard and Stony Brook.

In my free time, I enjoy working on DIY projects, capturing images of nebulae and galaxies within the night sky, tracking and communicating with satellites using amateur radio, and more. I also enjoy playing musical instruments, including the oboe, saxophone, and organ/piano.
