Stephen C. Stearns (born December 12, 1946) is an American biologist, and the Edward P. Bass Professor of Ecology and Evolutionary Biology Emeritus at Yale University. He is known for his work in life history theory and evolutionary medicine.

## Early life and education

Stearns was born in Kapaau, Hawaii and raised in Hawi, Hawaii. He completed his Bachelor of Arts degree at Yale University in 1967. He then pursued a Master of Science degree at the University of Wisconsin, Madison, graduating in 1971. Following this, he earned a PhD from the University of British Columbia in 1975. In 1978, they were awarded a Miller Fellowship at the University of California, Berkeley.

## Career

From 1978 to 1983, Stearns served as an Assistant Professor in the Department of Biology at Reed College. He then became a Professor of Zoology at the University of Basel, a position he held from 1983 to 2000. During this period, Stearns also served as the Managing Editor of the Journal of Evolutionary Biology from 1986 to 1991. From 1991 to 1998, he was the President of the Tropical Biology Association. Additionally, he chaired the European Science Foundation Program in Population Biology from 1994 to 1998 and served as Vice President of the Society for the Study of Evolution in 1995. Stearns was also the Dean of the Faculty of Science at the University of Basel from 1995 to 1996. From 2002 to 2005, he chaired the Department of Ecology and Evolutionary Biology at Yale University, where he has been the Edward P. Bass Professor of Ecology and Evolutionary Biology since 2000.

## Investment in Infrastructure

In 1987, Stearns helped to found the European Society for Evolutionary Biology (ESEB) and later served on its council as well as its president. He also founded the Journal of Evolutionary Biology, ESEB's main journal, and served as its first managing editor from 1986 to 1991 before later joining its Editorial Board. In 1991, alongside Tim Clutton-Brock, they founded the Tropical Biology Association. Additionally, they founded the online open-access journal "Evolution, Medicine, and Public Health" in 2013.
