description Bruce Campbell Overview
Bruce Campbell is a Canadian astronomer recognized for his foundational contributions to the radial-velocity method of detecting extrasolar planets. Working with colleagues Gordon Walker and Stephenson Yang in the 1980s and 1990s, he developed sensitive Doppler spectroscopy techniques to measure the tiny wobbles in stars caused by orbiting planets. In 1988, this team reported evidence for a substellar companion orbiting the star Gamma Cephei Ab, which was later confirmed as one of the earliest exoplanet discoveries. His work established the technical groundwork for future exoplanet surveys.
