Principal Investigator

David Gresham
Professor of Biology

Professor David Gresham is a biologist interested in adaptive evolution, cell growth and quiescence, and gene expression regulation.  David began as an Assistant Professor in the Center for Genomics and Systems Biology in the Department of Biology at NYU in 2009.  From 2004 – 2009, David was a postdoctoral fellow in the laboratory of David Botstein at Princeton University. From 2001 – 2004 David was a Research Editor at Nature Genetics.  In 2001, David completed a PhD in human genetics at Edith Cowan University in Perth, Australia under the mentorship of Luba Kalaydjieva. David’s doctoral thesis on medical and population genetics of the Romani people is available here. David obtained a BSc from McGill University in Montreal, Canada with a major in Biochemistry and a minor in Prehistoric Archaeology.  At NYU, David teaches classes in human genetics, statistics, and computational biology, is the faculty director of bioinformatics and the co-director of the NIH-supported QBIST PhD training program.  In 2022 Professor Gresham was appointed Vice Dean of the Graduate School of Arts and Sciences.
