Angela V. Olinto, the Albert A. Michelson Distinguished Service Professor in the Department of Astronomy and Astrophysics, has been appointed dean of the Division of the Physical Sciences at the University of Chicago.

Olinto is a leading scholar in astroparticle physics and cosmology, focusing on understanding the origin of high-energy cosmic rays, gamma rays and neutrinos. Her appointment as dean is effective July 1.

“Angela brings depth of University experience and scholarly expertise to this leadership role, making her an excellent choice as dean,” wrote President Robert J. Zimmer and Provost Daniel Diermeier in announcing her appointment.

Olinto’s research includes important contributions to the physics of quark stars, inflationary theory and cosmic magnetic fields. She currently leads NASA sub-orbital and space missions to discover the origins of high-energy cosmic rays and neutrinos. This includes a NASA-funded balloon mission planned for 2022 that will use an ultra-sensitive telescope to detect cosmic rays and neutrinos coming from deep space.

“I am thrilled and humbled to be appointed to lead this historic and dynamic division, home to visionary scholars who constantly redefine the boundaries of the physical and mathematical sciences. I look forward to collaborating with faculty, students and staff to advance the important work of the division,” Olinto said.

Olinto joined the UChicago faculty in 1996 and served as chair of the Department of Astronomy and Astrophysics from 2003 to 2006 and from 2012 to 2017. She is the leader of the POEMMA and EUSO space missions and a member of the Pierre Auger Observatory, which are international projects designed to discover the origin of high-energy cosmic rays. She is a fellow of the American Physical Society, was a trustee of the Aspen Center for Physics, and serves on advisory committees for the National Academy of Sciences, U.S. Department of Energy, the National Science Foundation and NASA.

Olinto’s awards and honors include the Chaire d'Excellence Award of the French Agence Nationale de la Recherche in 2006, the University’s Llewellyn John and Harriet Manchester Quantrell Award for Excellence in Undergraduate Teaching in 2011, and the Faculty Award for Excellence in Graduate Teaching and Mentoring in 2015. Olinto received her undergraduate degree from Pontificia Universidade Catolica in Rio de Janeiro, Brazil and her doctoral degree from the Massachusetts Institute of Technology.

Olinto succeeds Edward “Rocky” Kolb, the Arthur Holly Compton Distinguished Service Professor of Astronomy & Astrophysics, whose work over the last five years enhanced the division’s historic strengths as a leading center of scientific discovery. Kolb will return to his full-time work on the faculty next month.

The selection of the new dean by Zimmer and Diermeier was informed by the recommendations of an elected faculty committee chaired by Stuart A. Kurtz, professor in the Department of Computer Science.
