Angela Villela Olinto (born July 19, 1961) is an astroparticle physicist and professor at the University of Chicago as well as the dean of the Physical Sciences. Her work is focused on understanding the origin of high-energy cosmic rays, gamma rays, and neutrinos. Childhood and education Olinto was born in Boston, Massachusetts, during her father's graduate studies at the Massachusetts Institute of Technology. The family moved back to Rio de Janeiro, Brazil, when she was a toddler. She lived in Rio and Brasilia and received her bachelor's degree in physics from Pontificia Universidade Catolica in 1981. As she was finishing her undergraduate studies, she became ill with what was later diagnosed as polymyositis. She returned to MIT and received her Ph.D. in physics in 1987. Career After her Ph.D., Olinto joined the Fermilab Theoretical Astrophysics Group as a postdoc. From Fermilab, Olinto moved to the University of Chicago where she became the first woman to serve as a professor in the Department of Astronomy and Astrophysics. Starting in 1996, she also began a joint appointment with the Enrico Fermi Institute. She served as chair of the Department of Astronomy and Astrophysics from 2003-2006 and again from 2012-2017. In 2006, she received the Chair d’ Excellence Award from the Agence Nationale de la Recherche and served as visiting professor in the Laboratoire d’AstroParticule et Cosmologie (APC). In 2017, Olinto was named the Albert A. Michelson Distinguished Service Professor in the Department of Astronomy and Astrophysics. In 2018, she became the first female dean of the Physical Sciences Division at the University of Chicago. Olinto has given over 500 lectures worldwide and published over 250 papers. Research Throughout Olinto's career, she has made theoretical and experimental contributions to astroparticle physics, including contributions to the study of the structure of neutron stars, inflationary theory, the origin and evolution of cosmic magnetic fields, the nature of dark matter, and the origin of the highest energy cosmic particles: cosmic rays, gamma-rays, and neutrinos. Olinto emerged as a leader of the science behind the 3,000 km2 Pierre Auger Observatory in Malargue, Argentina, built and operated by a 19-country collaboration. Her group pioneered in depth studies of the physics and astrophysics of ultra-high energy cosmic ray (UHECR) including the propagation and neutrino production of UHE nuclei and acceleration models based on newborn pulsars. Starting in 2012, Olinto served as the United States principal investigator of JEM-EUSO (Extreme
