William C. Ratcliff is a Professor in the School of Biological Sciences at Georgia Institute of Technology and serves as the Director of the Interdisciplinary Ph.D. Program in Quantitative Biosciences (QBioS). He is widely recognized for his research on the evolution of multicellularity, social evolution, and bet hedging, combining experimental and theoretical approaches. His work often explores how single-celled organisms transition to multicellular life forms, with notable studies involving yeast models.

Dr. Ratcliff earned his Ph.D. from the University of Minnesota in 2011, where he conducted research on microbial ecology and evolution. His groundbreaking work includes the experimental evolution of multicellularity, which has been featured in high-impact journals such as Nature Communications and Proceedings of the National Academy of Sciences. He has also contributed to understanding ecological and evolutionary dynamics in microbial communities.

At Georgia Tech, Dr. Ratcliff leads an active research lab focused on evolutionary biology and biophysics, mentoring students and postdoctoral researchers. His contributions to science include both fundamental insights into multicellular evolution and applications in biotechnology.
