J. Ritchie Patterson

Not to be confused with the weightlifter Richie Patterson.

Ritchie Patterson is a physicist at Cornell University known for her research using the Large Hadron Collider to examine dark matter and the disappearance of antimatter. She is a fellow of the American Physical Society and an elected member of the American Association for the Advancement of Science. She attended Cornell and the University of Chicago where she studied physics.

Education and career

Patterson has a B.A. from Cornell University (1981) and a Ph.D. from the University of Chicago (1990). Following her Ph.D., she returned to Cornell where was promoted to professor in 2005.^[1] Patterson is the director of the Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE) and the Center for Bright Beams (CBB),^[2] a science and technology center funded by the National Science Foundation,^[3] led by Cornell. This Center works to increase the brightness of electron beams in order to provide new capabilities for scientific research, industry and machine.^[4] This center involves ten colleges and universities and three national labs, is exceptionally collaborative and highly interdisciplinary.

Research

Patterson's research centers on the use of the Large Hadron Collider to search for particles with long lifetimes.^[1]
