# Jon Seger

Jon Allen Seger is an American evolutionary ecologist, and Distinguished Professor of Biology at the University of Utah. He helped develop the theory of bet-hedging in biology. His work has appeared in leading scientific journals such as Nature, Science, Nature Genetics, Molecular Biology and Evolution, Journal of Evolutionary Biology, as well as popular magazines such as Scientific American.

## Biography

Dr. Seger attended UC Santa Barbara for his undergraduate studies, where he received a B.A. in English in 1969. Following college, he worked at the National Museum of Natural History on an assignment to help the museum establish public environmental education programs. He then enrolled at Harvard University, where he received his EdM in 1972 and his PhD in Biology in 1980. Much of his early work concerned models of sex ratio evolution and a variety of social insects (such as the Vespidae wasps). This work often took the form of mathematical models built from 'first principles' (such as his 1986 paper written with Robert Trivers). Following his PhD he held postdoctoral positions at the University of Sussex (1981-1982), the University of Michigan (1982-1983), and Princeton University (1983–86). He joined the faculty at the University of Utah in 1986.

## Career

His latest work concerns applications of coalescent theory to population genetics, particularly the mtDNA of whale lice, although members of his lab work on a variety of applied and theoretical topics that range from evolutionary ecology and genetics to mathematical biology and coalescent theory. In addition, he recently received an NSF grant to continue his work on the so-called "missing heritability" problem. His whale lice work had already shown that a genome should have many weakly deleterious mutations of small effect taken on their own but potentially large effect when taken together. This implies that the "missing" genes sought by, for example, human geneticists aren't actually missing: there are simply a lot more genes have a very small effect on fitness by themselves but have can have a large effect when the effects are combined.
