About

Roberta L. Millstein is an Emerit Professor in the Department of Philosophy at UC Davis, retired from teaching but still researching.  She is a AAAS Fellow (elected 2022). She is affiliated with the Science and Technology Studies (STS) Program and she co-runs UCD's PhilBio Lab with Jim Griesemer.

She is a Co-Editor of the peer-reviewed open-access online journal Philosophy, Theory, and Practice in Biology. She is also a Co-Chair of the History and Philosophy of Science section and a member of Council for the American Association for the Advancement of Science, Pacific Division (AAAS-PD). She is on the editorial boards for the Stanford Encyclopedia of Philosophy and the journal Philosophy of Science.

For several years, she has worked with the students, staff, and faculty of Fossil Free UCD, which successfully initiated a campus-wide Fossil Fuel-Free Pathway Plan and whose efforts are ongoing. Since May 2023, she has been a member of the Sierra Club Yolano Group Management Committee.

Research Focus

Professor Emerit Millstein's research is in the philosophy of science, the history & philosophy of biology, and environmental ethics. She is particularly interested in evolutionary biology, ecology, and environmental issues, and the intersections between them.

With respect to ecology, she has examined the historical and contemporary connections between ecology and population genetics. As part of a more extensive research project, she has re-interpreted and defended the work of 20th century ecologist (forester, wildlife manager, conservationist) Aldo Leopold, analyzing land communities (roughly similar to biotic communities/ecosystems), interdependence, functions/functioning, and predator/prey dynamics. Inasmuch as these ideas arise in the context of Leopold's land ethic, this project is also a project in environmental ethics. She has written an analysis and defense of the land ethic, The Land Is Our Community: Aldo Leopold's Environmental Ethic for the New Millennium. The book is now shipping and is published open access (downloadable for free) with the University of Chicago Press. Other work in environmental ethics examines the implications of the environmental impacts of GMOs and argues for how we ought to think of the field of environmental ethics.

With respect to evolutionary biology, she has particularly focused on central processes in evolution such as natural selection, random drift, sexual selection, and social selection, as well as central concepts in evolution such as fitness, population, metapopulation, race, and environment. This has included analysis of the general philosophy of science concepts of chance, probability, causation, causal processes, and determinism/indeterminism, and the ways in which they manifest (or fail to manifest) within evolutionary processes. Her conceptual work has been informed by her historical work, which includes analysis of some central 20th century debates in evolutionary biology, such as the neutral and “nearly neutral” theories of evolution and the empirical study of the land snail Cepaea nemoralis in the wild.
