Deirdre Brekken, Ph.D.

Assistant Dean for Postdoctoral Affairs

Assistant Dean

Department: Division of Basic Science Graduate Program, Pharmacology

Biography

Dr. Deirdre Brekken received her Bachelor of Engineering degree from Vanderbilt University and her Ph.D. degree from UT Southwestern Graduate School of Biomedical Sciences. Her graduate research was focused on the characterization of trypanosoma brucei gamma-glutamylcysteine synthetase, an essential enzyme in the biosynthesis of trypanothione.  She completed her postdoctoral training at the Seattle Biomedical Research Institute in Seattle, Washington where she studied the protein kinase CK2 from T. brucei.  She returned to UT Southwestern in 2002 as a faculty member and Lead Scientist in the Alliance for Cell Signaling to study phosphoproteins and their phosphorylation sites using proteomic techniques.

Dr. Brekken has now stepped away from the bench and is the Assistant Dean for Postdoctoral Affairs.  She directs the Postdoctoral Certificate Training Program and oversees the appointments and career development of the nearly 600 postdocs training at UT Southwestern.
