Francis "Frank" J. Doyle III (born 1963) is an American engineer and academic administrator. He is the dean of the Harvard John A. Paulson School of Engineering and Applied Sciences and the John A. and Elizabeth S. Armstrong Professor of Engineering and Applied Sciences. Doyle is also affiliated with the Division of Sleep Medicine of Harvard Medical School. On December 15, 2022 it was announced that Doyle will serve as the 14th provost of Brown University starting in the 2023 academic year. In 2021, Doyle was elected a member of the National Academy of Engineering for insights into natural biological control systems and innovative engineering of diabetes control devices. Biography Francis J. Doyle III was born in Philadelphia in 1963. His family moved to Newark, Delaware when Francis was 2. His father worked as a chemical engineer. Doyle completed his undergraduate studies at Princeton University in 1985, receiving a B.S.E. in chemical engineering. He received a M.S. (C.P.G.S.) in chemical engineering from Cambridge University in 1986, and Ph.D. in chemical engineering from the California Institute of Technology in 1991. Doyle joined Harvard in 2015, becoming the first John A. Paulson Dean. A distinguished scholar in chemical engineering, he previously served as Associate Dean for Research at the University of California, Santa Barbara's College of Engineering, where he also served as chair of the Department of Chemical Engineering. At UCSB he was a founding co-Director of the UCSB-MIT-Caltech Institute of Collaborative Biotechnologies. Prior to his appointment at UCSB, Doyle was a professor in the Department of Chemical Engineering at the University of Delaware (1997-2002), and was a professor in the School of Chemical Engineering at Purdue University (1992-1997). Between his graduate studies and his first academic appointment, he completed postdoctoral studies at the DuPont Company. Research As a scholar, Doyle applies systems engineering principles to the analysis of regulatory mechanisms in biological systems. His work includes the design of drug-delivery devices for diabetes (i.e., the artificial pancreas); modeling, analysis, and control of gene regulatory networks underlying circadian rhythms; and computational analysis for developing diagnostics for post-traumatic stress disorder. Doyle also applies control schemes to nonlinear, multivariable, constrained industrial processes such as particulate systems and pulp and paper operations, and works on control aspects of sheet/film processes. Honors and recognition Doyle has received a number of honors throughout his career, including: National Academy of Engineering (NAE) Member, 2021 National Academy of Medicine
