Mohamed A. Noor

Mohamed A. Noor is an American evolutionary biologist and geneticist renowned for his research on the genetic mechanisms underlying speciation. He is the Dean of Natural Sciences at Duke University's Trinity College of Arts and Sciences, having previously served as a professor at Duke University and chair of the Biology department. His influential work, primarily using Drosophila model systems, has advanced understanding of reproductive isolation, hybrid incompatibility, and the role of recombination in evolution.

Biography

Born in Cleveland, Ohio, Noor earned his Bachelor of Science degree from the College of William & Mary in Virginia. He then pursued his doctoral studies at the University of Chicago, completing his Ph.D. under the mentorship of renowned evolutionary biologist Jerry Coyne. Following his doctorate, he conducted postdoctoral research at the University of California, Davis before beginning his independent academic career. He held faculty positions at the University of Texas at Arlington and later at Duke University, where he rose to leadership roles. He also served as the Margaret and Herman Sokol Professor at the University of Chicago before returning to Duke University as dean.

Research and career

Noor's research program centers on the genetics of speciation, particularly using species of the fruit fly genus Drosophila, such as Drosophila pseudoobscura and Drosophila persimilis. A major focus has been identifying and characterizing "speciation genes" that contribute to reproductive isolation between closely related species. His lab provided early empirical evidence for the role of chromosomal inversions in suppressing recombination in hybrids, thereby maintaining co-adapted gene complexes that underlie hybrid sterility or hybrid inviability. This work supported the reinforcement model of speciation, where natural selection strengthens pre-zygotic isolation to prevent maladaptive hybridization. His research integrates approaches from population genetics, molecular evolution, and comparative genomics to understand evolutionary processes.

Awards and honors

Noor has received significant recognition for his scientific contributions and educational leadership. He is a recipient of the prestigious Presidential Early Career Award for Scientists and Engineers (PECASE). He was elected a Fellow of the American Academy of Arts and Sciences and the American Association for the Advancement of Science (AAAS). In 2018, he was awarded the Thomas Hunt Morgan Medal by the Genetics Society of America for lifetime contributions to the field of genetics. He has also been honored with the David and Janet Vaughan Brooks Award from Duke University and is a past president of the Society for the Study of Evolution.

Selected publications

Noor has authored numerous influential papers and books. His 2002 paper in *Science* on "**Reinforcement and the genetics of nonrandom mating**" was a landmark study. His textbook, "**You're Hired! Now What?**" provides guidance for new science faculty. Other notable works include studies in *Nature*, *Proceedings of the National Academy of Sciences* (PNAS), and *Evolution* on topics like the genetics of hybrid male sterility, the Drosophila miranda genome, and the evolutionary dynamics of recombination hotspots. His research is frequently cited in the broader literature on evolutionary biology.

Service and leadership

Noor has held extensive service and leadership roles in the scientific community and academia. He served as the President of the Society for the Study of Evolution and as an editor for major journals including *Evolution* and *PLOS Genetics*. At Duke University, he served as Chair of the Biology Department before becoming the Dean of Natural Sciences for the Trinity College of Arts and Sciences. In this decanal role, he oversees departments including Biology, Chemistry, Mathematics, Physics, and Statistical Science. He is also deeply committed to science education, outreach, and promoting diversity within STEM fields.
