Seminar Series

The Department of Genetics hosts a different speaker every Monday of the academic year, with invitees ranging from postdoctoral researchers to prominent scientists presenting a broad array of current, genetics-related research. Our series is cosponsored with the Department of Cell and Developmental Biology and the Institute for Regenerative Medicine. Click here to view the schedule.

Recent Faculty Additions

We are pleased to announce the recruitment of Golnaz Vahedi, Ph.D.Golnaz received her Ph.D. in Computational Biology from Texas A&M in 2009, where she studied gene regulatory networks applying Boolean probabilistic modeling and other methods. After developing her interest in regulatory networks controlling gene expression, Golnaz joined Dr. John O’Shea’s laboratory at the National Institutes of Health in 2009. During her postdoctoral training Dr. Vahedi made seminal findings in the area of epigenetic and transcription factor control of cell fate in the immune system. Golnaz will join the Department as a tenure track Assistant Professor on May 1, 2015. Her arrival is expected to further strengthen and expand the Department's capacities in the computational and bioinformatics aspects of immunogenetics.
