Dr. Cox is 2CI Professor of Neuroscience and Biology, Director of the Center for Neuromics, and Dean’s Faculty Associate for Faculty Development. He graduated with Honors from Wake Forest University where he conducted undergraduate research as the William L. Wyatt Scholar in Biology at both Wake Forest and the Marine Biological Laboratory. Dr. Cox conducted his doctoral studies at Duke University under the direction of Dr. Haifan Lin in which he identified and characterized members of the piwi gene family in regulating asymmetric stem cell division. Based upon his graduate research, Dr. Cox received a number of prestigious national and international awards including the Harold M. Weintraub Graduate Student Award and 1st Runner-Up for the Larry Sandler Memorial Award sponsored by the Genetics Society of America. In 2000, he moved to UCSF where he conducted postdoctoral studies in Developmental Neuroscience as a Jane Coffin Childs Fellow for Medical Research and an HHMI Research Associate in the laboratory of Dr. Yuh-Nung Jan.
In 2004, he accepted a faculty position at George Mason University where he was Graduate Program Director, Director of Cellular Imaging, and Principal Investigator in the Krasnow Institute for Advanced Study. During his tenure at George Mason, Dr. Cox was the recipient of numerous awards for teaching and mentoring awards including the 2013 University Teaching Excellence Award, (2) College of Science Teaching Excellence Awards, and the inaugural OSCAR Mentoring Excellence Award. In 2012, Dr. Cox received a national mentoring award in the Biological Sciences (1 of 3) from the Council on Undergraduate Research. In 2011, Dr. Cox received the J. Shelton Horsley Research Award from the Virginia Academy of Science which is the highest honor bestowed by this agency.
In Fall 2014, Dr. Cox joined the Neuroscience Institute at GSU. In 2017, he received the College of Arts and Science Outstanding Graduate Mentoring Award and in 2018 was a finalist for the Nature Awards for Mentoring in Science, South Division. Apart from his research program, Dr. Cox serves on the editorial boards of several scientific journals and on grant review panels for a variety of agencies including the NIH, NSF, DOD, and Wellcome Trust, UK.
Cox Lab research interests revolve around developmental neurogenetics, neurogenomics, molecular neuroanatomy, computational neuroscience, and behavioral neurobiology. We are particularly interested in elucidating the cellular and molecular mechanisms underlying the specification and modulation of neural connectivity with an emphasis on the control of dendrite development and the functional relationships between dendrite morphogenesis and behavior. Current behavioral interests center on molecular and neural circuit bases of thermosensory nociception and multimodal sensory processing and integration. Research in the Cox Lab is funded by the National Institutes of Health. Recent graduates from the laboratory have secured faculty positions as well as highly competitive postdoctoral positions at the NIH, Harvard Medical School, Whitehead Institute (MIT) and ICFO (Barcelona).
