Tracey Holloway, jointly appointed professor in the Nelson Institute for Environmental Studies and the Department of Atmospheric and Ocean Sciences at the University of Wisconsin–Madison, has been elected as a Fellow of the American Geophysical Union (AGU). She joins the 2025 Class of Fellows, a distinguished group of just 52 individuals worldwide recognized for their exceptional contributions to Earth and space sciences. Since the program’s inception in 1962, fewer than 0.1 percent of AGU members have received this prestigious honor each year.
AGU Fellows are selected for their scientific eminence, demonstrated through breakthroughs, discoveries, and innovations that advance the field. Holloway was chosen for her exemplary leadership and outstanding scientific achievements, adding to her long record of impact in energy analysis and policy. She and the other honorees will be recognized at AGU25, held December 15–19, 2025, in New Orleans, Louisiana, under the theme Where Science Connects Us.
For more than 20 years, Holloway has worked with students, scientists, and outreach staff to better understand the air we breathe, advancing research that bridges science and policy through the use of satellite data, computer models, and ground-based measurements. She is a two-time Team Lead of NASA’s Health and Air Quality Applied Science Team (HAQAST), chairs UW–Madison’s Energy Analysis and Policy program, and is based at the Nelson Institute’s Center for Sustainability and the Global Environment (SAGE) where she leads the Holloway Group. Widely recognized for her leadership in research, education, and outreach, Holloway has received honors including election to the National Academy of Medicine and the AGU Ascent Award, and she serves on advisory boards and committees spanning science, policy, and public engagement.
