Robert M. Schofield (born 1960) is an American physicist, and a Research Associate Professor at the University of Oregon (UO) who was elected a Fellow of the American Physical Society in 2014.
Early life and education
Born in 1960,[1] Schofield's bachelor's degrees are in experimental psychology (1982) and in physics (1983) from Brigham Young University. He earned a Ph.D. in 1990 at the University of Oregon, with the dissertation, X-ray microanalytic concentration measurements in unsectioned specimens: A technique and its application to zinc, manganese, and iron enriched mechanical structures of organisms from three phyla, advised by Harlan W. Lefevre.[2]
Schofield held postdoctoral positions in the university's Institute of Molecular Biology and at Lund University. He then joined the UO as a research faculty member,[3] and was promoted in 2020 to Research Associate Professor.[4]
Career
Schofield's research interests include gravitational waves and structural biophysics.[5] He has been described as "an inter-disciplinarian, merging principles from physics, biology and materials science in pursuit of his passions".[6]
LIGO
Schofield's work to enhance the sensitivity of the Laser Interferometer Gravitational-wave Observatory (LIGO) has allowed physicists to detect gravitational waves produced by colliding black holes.[3] LIGO's biggest challenge is detector noise, from seismic waves, thermal motion, and photon shot noise, disturbances that could mask the signals from gravitational waves.[8] LIGO can detect "a truck rumbling past, the humming of a refrigerator in a nearby building, or the distant flutter of a plane’s propellers".[7]
Laura Hamers wrote, "Gravitational waves are so faint by the time they reach Earth that they can be drowned out by closer-to-home disturbances most of us wouldn't even notice. For example, the early LIGO detectors were so sensitive that water going over a dam 30 kilometers away could throw off the data, said Schofield, who co-leads the environmental monitoring at the Hanford detector. He and his colleagues have placed a bevy of sensors around the detectors, which keep track of external disruptions like rumbling traffic or crackling lightning."[9]
Elected a Fellow of the American Physical Society, Schofield was cited for "leadership in identifying and mitigating environmental factors which impact the sensitivity of terrestrial gravitational wave detectors and elimination [of] spurious noise sources in LIGO."[10]
