Dr. Barak received his bachelor degree (BSc) in animal science and his Doctor of Veterinary Medicine (DVM) from The Hebrew University of Jerusalem (Rehovot, Israel). After working for two years as a full-time small animal veterinarian he switched to part-time and returned to academia. He received his PhD in the area of bone biomechanics and his teaching certificate (biology teacher for high schools) from the Weizmann institute of Science (Rehovot, Israel). During his PhD, his research focused on the relation between bone structure and function using the rat as an animal model. Next, Dr. Barak accepted a two-year joint Postdoctoral position at the Department of Human Evolutionary Biology at Harvard University (Cambridge, MA) and The Max Planck Institute for Evolutionary Anthropology (Leipzig, Germany). There, he did research on extinct hominins bipedal locomotion (Australopithecines) and its manifestation in the structure of the ankle's trabecular bone. Dr. Barak’s academic background includes one year as a lecturer at the Department of Human Evolutionary Biology at Harvard University (Cambridge, MA) and five years as an Assistant Professor and one year as an Associate Professor at the Department of Biology at Winthrop University (Rock Hill, SC). At Winthrop University Dr. Barak taught the “Human Anatomy” course, his own “Biology of Bone” course, and other undergraduate and graduate courses (both for Biology and non-Biology majors). Aside from his teaching, Dr. Barak maintained an active lab at Winthrop University and have mentored close to twenty undergraduate and four graduate students. Dr. Barak’s research focuses on studying the relation between bone structure and mechanical properties by using a three-prong approach: (I) mechanically testing bone tissues from various bones and animals, (II) 3D printing bone structures (both healthy and pathological samples) and mechanically testing them, and (III) using Finite Element Analysis (FEA) to map stresses and strain distribution and to predict areas of weakness which are prone to failure.
Dr. Barak’s research interests include bone biology in health and disease, bone biomechanics, bone adaptation (modeling and remodeling) Finite Element (FE) modeling, 3D Printing and animal locomotion.
