The first woman in her family to obtain a formal education, Betül Kaçar now directs a NASA Research Center focused on the origins of life. Her career spans institutions including the University of Arizona, Harvard University, and the Tokyo Institute of Technology, where she investigates how molecular evolutionary mechanisms inform our understanding of habitability on other planetary bodies.
Academic Foundation
Born in 1983 in Istanbul, Turkey, Kaçar began her academic trajectory by studying chemistry at Marmara University. She subsequently moved to Emory University, supported by a Howard Hughes Medical Institute undergraduate fellowship. Her doctoral research at the same institution specialized in biomolecular chemistry, specifically the relationship between enzyme structure and function, providing the technical basis for her later transition into the study of life's origins.

Kaçar held a NASA postdoctoral fellowship at the Georgia Institute of Technology before joining Harvard University in 2014, where she led an independent research group within the Department of Organismic and Evolutionary Biology. In 2015, she became a member of the Harvard Origins Initiative and received the Templeton Fellowship. Her research often involves the resurrection of ancient genes within modern microbial genomes to observe evolutionary processes. In 2025, she secured the Keck Foundation Award to investigate the evolution of ancient metabolisms.
Scientific Methodology and Innovation
Her work includes the development of the term paleophenotype, which reconstructs evolutionary histories to link contemporary biological components to ancient geological contexts. Kaçar has also identified evolutionary stalling, a mechanism where an organism incurs a fitness cost because a biological module fails to reach peak performance. Additionally, she proposed protospermia, a concept involving the application of prebiotic chemistry to foster life on other celestial bodies.
Leadership and Public Engagement
As a professor at the University of Wisconsin-Madison and an associate professor at the Earth-Life Science Institute in Tokyo, Kaçar maintains a significant role in international science networks. She co-founded SAGANet, a grassroots astrobiology outreach organization, and participated in the National Academies' panel on Mars exploration strategy. She has managed over $9 million in research funding and served as a global science coordinator for the ELSI Origins Network.
