Education and career

Presgraves earned his B.S. and an M.S. at the University of Maryland at College Park and a second M.S. and a Ph.D. in ecology and evolutionary biology from the University of Rochester. After completing his Ph.D, he was an Alexander von Humboldt Postdoctoral Fellow at the University of Munich and an NIH-NRSA Postdoctoral Fellow at Cornell University.[2]

Work

Presgraves' work has contributed to the current understanding of sexual selection, meiotic drive, and the X-Chromosome's evolutionary importance. His work has led to the confirmation of a phenomenon called the "large X-effect," which describes the integral role of the X-Chromosome as a wedge in driving speciation.[3]

Awards and recognition

In 2003, Presgraves was awarded the Dobzhansky Prize by the Society for the Study of Evolution in recognition of his accomplishments as an outstanding young evolutionary biologist. He was the first Dobzhansky Prize winner to have been trained by a previous recipient of the prize: H. Allen Orr.[2]
