There's a lot of interest building in this seminar.
He will be hosted by fellow bee scientist Brian Johnson, assistant professor, UC Davis Department of Entomology and Nematology.
Zayed leads a research program on honey bee behavioral genetics and genomics. In his talk, Zayed will summarize his group's recent findings on patterns of positive selection in the honey bee genome, and show how integrative genomic analyses can be used to chart the bee's genotype-phenotype map.
Zayed completed his bachelor's degree in environmental science with honors in 2000, and his doctorate in biology in 2006, both at York University. He was awarded the Governor General's prestigious Gold Medal in 2007 for his doctoral research on bee conservation genetics.
Zayed held a Natural Sciences and Engineering Research Council of Canada's Postdoctoral Fellowship at the University of Illinois' Department of Entomology from 2006 to 2008 in Charles Whitfield's Laboratory. He then served as a fellow for the Institute for Genomic Biology's Genomics of Neural and Behavioral Plasticity Theme (theme leader: Gene Robinson) at the University of Illinois from 2008 to 2009.
Zayed rejoined York University's Department of Biology as an assistant professor in 2009. He earned the Ontario Government of Research and Innovation's Early Researcher Award in 2010, and was promoted to associate professor in 2014. He received the Ontario Government of Research and Innovation's Early Researcher Award in 2010.
This isn't Zayed's first time visiting the UC Davis campus. A few years ago, he completed a queen bee instrumental insemination course, taught from bee breeder-geneticist Susan Cobey, then with the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis, and now with Washington State University.
Plans call for recording the seminar for later posting on UCTV. Coordinating the seminars is professor Steve Nadler. For a list of the next speakers, see this page.

A honey bee, that is.
Research entomologist Jay Evans of the USDA's Agricultural Research Service (USDA/ARS) will discuss "What's It Like Inside a Bee? Genetic Approaches to Honey Bee Health" at the UC Davis Department of Entomology and Nematology seminar from 12:10 to 1 p.m., Wednesday, Feb. 4 in 122 Briggs Hall.
The Marin County Beekeepers will host the bee scientist.
"Honey bees are the preferred agricultural pollinators worldwide, and are important natural pollinators in Europe, Asia, and Africa," Evans says. "The European honey bee, Apis mellifera, is both aided and abused by humans, leading to a worldwide distribution on one side, and alarming regional die-offs on the other. Primary causes of honey bee colony death range from inadequate nutrition to stress from chemical exposure and maladies caused by a diverse set of parasites and pathogens."
"Often, domesticated honey bees face two or more stress agents simultaneously. Genetic approaches are being used to determine and mitigate the causes of bee declines. Genetics screens are available for each of the major biotic threats to bees, and screens have been used to determine risk levels for these threats in the field. Thanks to extensive analyses of the honey bee genome, tools are also available to screen bees for heritable traits that enable disease resistance, and to query the expressed genes of bees to infer responses to chemicals and biological stress. This talk will cover genetic insights into honey bee health, disease resistance and susceptibility to chemical insults."
Evans received his undergraduate degree in biology at Princeton and his doctorate in biology from the University of Utah. He did a postdoctoral fellowship at the University of Georgia, where he became interested in honey bees. After a brief project on queen production at the University of Arizona, he joined the USDA/ARS as a research entomologist with the USDA-ARS Bee Research Laboratory, Beltsville, MD.
He is especially interested in insect immunity and in the abilities of social insects to evade their many parasites and pathogens. He focuses his projects on a range of bee pests including the American foulbrood bacterium, small hive beetles, nosema, viral pests and varroa mites.
Evans was an early proponent of the Honey Bee Genome Project and helped recruit and organize scientists interested in applied genomics for bees. He has improved and applied genetic screens for possible causes of colony collapse disorder and is now heading a consortium to sequence the genome of the Varroa mite in order to develop novel control methods for this key pest.
