Biographical Sketch

Tyler Johnson works on the axion direct-detection experiments ALPHA, HAYSTAC, and RAY, along with the neutrinoless double beta decay experiments CUORE and CUPID. Across both neutrino and axion searches, his work emphasizes signal processing and supporting the progression all the way from commissioning to data collection and analysis. 

Johnson grew up in Kansas, then studied at the University of Chicago for his undergraduate degree. He completed his Ph.D. in nuclear physics at Duke University working on the first search for neutrino-induced nuclear fission with the experiment he built and deployed to Oak Ridge National Laboratory called NuThor with the COHERENT Collaboration. That work was funded by the National Nuclear Security Administration’s Consortium on Monitoring, Technology & Verification where he was an Applied Anti-neutrino Physics Doctoral Fellow. This interest in nuclear non-proliferation melded with his work with the Stanford US-Russia Forum as an Arms Control Fellow.

Experiments

ALPHA, HAYSTAC, RAY

Baker, Barrett, Brown, Heeger, Lamoreaux, Lehnert, Maruyama

Science Goal: Search for axion dark matter using quantum and microwave technologies.

WL Involvement: Yale is responsible for systems engineering, cryogenics, and magnetics. Lamoreaux and Maruyama are PIs of HAYSTAC, Maruyama is spokesperson of ALPHA and PI of RAY.

CUORE & CUPID

Heeger, Maruyama

Science goal: Search for neutrinoless double beta decay, which could answer why we live in a Universe of matter, not antimatter.

WL involvement: Yale is responsible for detector calibration, the study of cosmogenic backgrounds, double beta decay analysis, & the search for solar axions. Heeger and Maruyama are CO-PIs of CUORE & CUPID.
