Dr. Clark is Chief of the Division of Pediatric Critical Care Medicine. Broadly speaking, his current research interests include mechanisms of cell death and neurological dysfunction after traumatic and ischemic brain injury, particularly in the developing brain. Laboratory efforts encompass in vitro and in vivo models of brain trauma and ischemia, and translational studies in patients suffering from these injuries. He also has a strong interest in pediatric neurocritical care, and established the first primary pediatric neurocritical care service in the world along with Dr. Michael Bell whom he recruited to serve as Director. He has established an infrastructure for the successful training of young investigators, and have served as the primary research mentor for over 25 clinical fellows, post-doctoral fellows, graduate students, and or medical students. He has been Principal Investigator on 9 NIH grants since 1996, served as primary sponsor for two K08 and two K12 awardees, served as Co-PI on the T32 grant, “Training in Pediatric Neurointensive Care and Resuscitation Research,” for the past 15 years, and has served on 62 NIH study sections since 2001. He has over 200 publications including over 140 peer-reviewed research manuscripts including publications in the FASEB Journal, Journal of Biological Chemistry, and Journal of Neuroscience. In a recent report by Thomas Reuters Web of Science’s SCIENCEWATCH he was listed as one of the top 25 most prolific authors of papers on traumatic brain injury in the world from 2001-2014. His publications have been highlighted in Science, Nature, Scientific American, Science & Vie (Paris), and The Wall Street Journal.
