Tracey Holloway Elected as AGU Fellow
October 1, 2025
Tracey Holloway, jointly appointed professor in AOS and the Nelson Institute for Environmental Studies, has been elected as an American Geophysical Union (AGU) Fellow. She joins a distinguished group of 52 individuals in the 2025 Class of Fellows, an honor bestowed annually by AGU to individuals who have made exceptional contributions to Earth and space sciences. Since the program’s inception in 1962, less than 0.1% of AGU members have been selected as Fellows each year.
AGU Fellows are recognized for their scientific eminence, demonstrated through breakthroughs, discoveries or innovations that advance the Earth and space sciences. Fellows act as external experts, advising government agencies and other organizations outside the sciences upon request. Holloway was selected for her exemplary leadership and outstanding scientific achievements, which have significantly advanced our understanding of air quality analysis and policy.
For over twenty years, Holloway has collaborated with students, scientists, and outreach staff to better understand the air we breath through satellite data, computer models, and ground-based measurements. She leads the Holloway Group at the Nelson Institute’s Center for Sustainability and the Global Environment (SAGE), is a two-time Team Lead of NASA’s Health and Air Quality Applied Sciences Team, and chairs UW–Madison’s Energy Analysis and Policy program. Her contributions have earned her election to the National Academy of Medicine, the AGU Ascent Award, and numerous honors for outreach, diversity, and mentoring.
“Tracey is a multi-talented individual who has made enormous contributions towards making our world better understood, more energy-secure, and with healthier air for all,” says AOS department chair Ankur Desai. “She runs an inclusive lab and has led multiple efforts to make all our community a more welcoming space for everyone who wants to participate in those efforts. It is wholly fitting for her to be awarded as AGU Fellow.”
Honorees will be recognized at AGU25, in New Orleans, Louisiana, December 15–19. Congratulations and well deserved, Tracey!
