Dr. Meir Barak's academic journey began at The Hebrew University of Jerusalem in Rehovot, Israel, where he earned his Bachelor of Science (BSc) in Animal Science and his Doctor of Veterinary Medicine (DVM). After dedicating two years to full-time small animal veterinary practice, Dr. Barak transitioned to part-time work and continued his academic education at the Weizmann Institute of Science in Rehovot, Israel, where he completed his PhD in bone biomechanics. During this time, he focused his research on the relationship between bone structure and function, utilizing the rat as an animal model. Concurrently, he obtained his teaching certificate, qualifying him as a high school biology teacher. Dr. Barak's postdoctoral work spanned two years in a joint position at Harvard University's Department of Human Evolutionary Biology in Cambridge, MA, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. His research during this period centered on extinct hominin bipedal locomotion, specifically in Australopithecines, and its manifestation in the ankle's trabecular bone structure. Following his postdoctoral studies, Dr. Barak spent a year as a lecturer at Harvard University's Department of Human Evolutionary Biology before joining Winthrop University in Rock Hill, SC. At Winthrop, he served as an Assistant Professor for five years and then as an Associate Professor for one year in the Department of Biology. During his tenure at Winthrop University, Dr. Barak developed and taught a diverse range of courses. These included "Human Anatomy," his self-designed "Biology of Bone" course, and various undergraduate and graduate courses catering to both Biology and non-Biology majors. Beyond his teaching responsibilities, Dr. Barak maintained an active research laboratory, where he mentored nearly twenty undergraduate and four graduate students. Dr. Barak's current research focuses on the relationship between bone structure and mechanical properties. He employs a three-pronged approach: mechanically testing bone tissues from various bones and animals, 3D printing and testing bone structures (both healthy and pathological samples), and using Finite Element Analysis (FEA) to map stress and strain distribution and predict areas prone to failure. His research interests span a wide range of topics within the field of bone biology, including bone health and disease, biomechanics, bone adaptation (modeling and remodeling), Finite Element (FE) modeling, 3D printing, and animal locomotion. Through this multifaceted approach, Dr. Barak hope to continue and contribute valuable insights to the scientific community and inspire the next generation of researchers.
