Warren Johnson

Warren Johnson is the Professor of Physics at Louisiana State University's Department of Physics & Astronomy, part of the College of Science. He holds a Ph.D. from Rutgers University (1974). His research focuses on experimental low-temperature physics with emphasis on gravitational wave detection through advanced antenna design and data analysis. He co-invented the TIGA (Truncated Icosahedral Gravitational Antenna) concept, leading national (TIGA) and international (OMEGA) collaborations. He contributed to site selection for LIGO, now a major experimental hub.

• Education: Ph.D., Rutgers University, 1974

Research interests include optimizing gravitational wave antennas like ALLEGRO, time series analysis for burst detection, and spherical detector configurations. His work addresses challenges in non-thermal noise reduction and directional source localization. Recent efforts aim to enhance cryogenic transducer sensitivity for next-gen detectors.

Collaborative projects include the IGEC-2 and LIGO Scientific Collaborations, with publications on pulsar gravitational wave limits and stochastic background searches. Awards/recognitions are not explicitly listed.

Advising/grants: No specific advisees listed, but leads experimental teams on ALLEGRO and TIGA projects. Involved in detector calibration (e.g., ALLEGRO calibration studies).

Labs/Teams: Active in LSU's gravitational wave research group, contributing to LIGO experiments and cryogenic sensor development initiatives.
