Jon Allen Seger is an American evolutionary ecologist, and Distinguished Professor of Biology at the University of Utah.
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).
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.
