Marc Mangel


Marc Mangel is an American mathematical biologist and professor emeritus known for his contributions to theoretical ecology, applied mathematics, and interdisciplinary environmental research. He is currently Distinguished Professor of Mathematical Biology Emeritus at the University of California, Santa Cruz, and Professor Emeritus in the Theoretical Ecology Group at the University of Bergen.

Early life and education

Mangel was born in New York City and grew up in the Chicago, IL region graduating from Highland Park High School. Mangel earned his B.S. in Physics with high honors from the University of Illinois in 1971. He completed an M.S. in Biophysics in 1972 at the same institution, and received a Ph.D. in Applied Mathematics and Statistics from the University of British Columbia in 1978. where he was supervised by Donald Ludwig and worked as a research assistant for Colin W. Clark. His PhD thesis concerned methods for computing the probability of the outcome of competition between two species of flour beetles. With Clark, he developed models of the tuna-purse seine fishery.

Career

From 1977 to 1980, Mangel worked as a scientific analyst at the Center for Naval Analyses, a federally funded research and development center supporting the United States Navy. As a CNA employee, he served as the representative of the Operations Evaluation Group at Naval Air Station Whidbey Island, working mainly on aspects of electronic warfare and search problems.
In 1980, Mangel joined the faculty at the University of California, Davis, where he held positions in the Department of Mathematics and the Department of Zoology, which later became the Department of Evolution and Ecology. During his tenure, he co-founded the university's Graduate Programs in Applied mathematics and in Population biology. He served as Chair of the Department of Mathematics from 1984 to 1989 and as founding Director of the Center for Population Biology from 1989 to 1993.
In 1996, Mangel moved to the University of California, Santa Cruz, where he held appointments in both Environmental studies and the Department of Applied mathematics and statistics. His administrative roles at UCSC included serving as Associate Vice Chancellor for Planning and Programs, Chair of the Department of Applied Mathematics and Statistics, and Chair of the Program in Technology and Information Management. Mangel was on the founding board of directors of FishWise, and chaired the board from 2013–2020. He retired in July 2013 and returned one month later with the title of Distinguished Research Professor, which he held until July 2025. In 2014, Mangel appeared as the Independent Expert for Australia in the case in the International Court of Justice Whaling in the Antarctic: Australia v. Japan, in which the Court concluded that the Japanese Special Permit Whaling Program contravened the International Convention for the Regulation of Whaling.
Mangel has worked with colleagues in the Theoretical Ecology Group at the University of Bergen since 1994 and was appointed Adjunct Professor in 2010, moving to Professor Emeritus of Biology in 2021 on his retirement from UiB.

Research

Mangel's research focuses on the use of mathematical and theoretical approaches in ecology, evolutionary biology, and conservation biology. He has contributed to areas such as behavioral ecology, host–parasitoid interactions, sustainable fisheries management, and conservation biology. He is known for linking theoretical models with empirical data to address practical challenges.
Mangel’s early research in mathematical biology involved the development of new methods for computing the probability of the outcome in stochastic competition between two computing species, motivated by Park’s classic study of competition between species of flour beetle. During his research with Colin W. Clark on tuna fisheries, Mangel developed an interest in the search for schools of fish by fishing vessels.
After moving to CNA, he developed methods for determining the distribution of location and probability of success in search for a moving object, thus extending the work of Bernard Koopman on Bayesian search theory.
With his move to UC Davis, Mangel’s interest in search problems immediately translated to search problems in agricultural pest control, fisheries, and behavioral ecology. He spent the vast majority of his career working on problems from those fields, with a focus in Pasteur's quadrant.
