    Before to joining Regis College as the Neuroscience Program Director in 2016, Dr. Threlkeld was an Associate Professor at Rhode Island College and coordinator for the Behavioral Neuroscience program. Prior to that he was Research Associate in Pediatrics in the Perinatal Brain Research Laboratory at Women and Infants Hospital and the Warren Alpert Medical School of Brown University, where he studied blood brain barrier dysfunction associated with neonatal brain injury. He was also a teaching assistant at the University of Connecticut and has served as an adjunct Assistant Professor of Pediatrics at Women and Infants Hospital in collaboration on NIH funded projects. In addition, Dr. Threlkeld currently serves as a co-investigator and Adjunct Associate professor in collaboration with the Neurotrauma and Brain Barriers lab in the Department of Emergency Medicine at Rohde Island Hospital, in Providence, RI. Dr. Threlkeld has a long history engaging undergraduate students in high impact NIH funded Neuroscience research. He is a member of the Society for Neuroscience and Faculty for Undergraduate Neuroscience.


    Doctor of Philosophy (PhD) in Behavioral Neuroscience, University of Connecticut, 2008

    Master of Arts in Behavioral Neuroscience, University of Connecticut, 2006

    Bachelor of Arts in Psychology, University of Portland, 2003


    Dr. Threlkeld’s research centers on understanding the anatomical and behavioral consequences of disrupted forebrain development resulting from injury or teratogenic events and how early behavioral experience or pharmacological intervention can improve outcome and promote neuronal plasticity. Current projects involving undergraduate students at Regis include investigations into the role of inflammation in pathogenesis of neonatal hypoxia/ischemia, behavioral outcome and behavioral and pharmacological intervention strategies. A second line of work is focused on the consequences of mild traumatic brain injury and anti-inflammatory treatment approaches on learning, auditory sensory processing and neuroanatomical outcomes in rodent models.
