The Axion Longitudinal Plasma HAloscope (ALPHA) explores a new approach to axion dark matter detection using metamaterial wire arrays to form plasma haloscopes. In these systems, the resonant frequency is set by the effective plasma frequency rather than the physical cavity dimensions, allowing sensitivity to axion masses that are inaccessible to traditional haloscopes.

I serve as electronics working group lead for ALPHA and designed the receiver, control, and signal-processing architecture for Phase I of the experiment. I led the design, laboratory validation, and system integration of the Phase-I electronics, positioning ALPHA to probe the 40–80 μeV axion mass range.

Building on this role, I now oversee the system-level integration and testing of the full ALPHA Phase-I experiment at Yale, coordinating resonator, cryogenic, data acquisition, and magnet subsystems to guide the transition from subsystem development to sustained science operations. This work establishes the technical foundation required to extend plasma haloscopes to much higher frequencies and definitively test post-inflationary axion production scenarios.
