Experimental cosmology & particle physics — axion dark matter and CMB B-modes
I’m a Mossman Postdoctoral Fellow at Yale University, working at the intersection of particle physics and cosmology. I build and study ultra-sensitive instruments designed to detect faint signals from dark matter and the early universe.
My research has two main threads:
- Axion dark matter detection (HAYSTAC, ALPHA): resonant RF detectors, and quantum-limited / quantum-enhanced readout
- CMB instrumentation & analysis (Simons Observatory): readout performance, time-ordered preprocessing, noise modeling, and inflationary B-mode searches
I got into this field because I love turning big physics questions into real hardware and measurement—creative, hands-on science that’s as much about invention as it is about equations.
