Sun Peck, PhD


Assistant Professor of Medicine, Division of Clinical Pharmacology

Brief Description

Dr. Peck received her doctorate in chemical biology from Harvard University, where she developed novel molecular evolution techniques to study protein-protein interactions and protein function. Her interests in macromolecular chemistry led her to pursue postdoctoral research in lysosomal storage disorders and pathological consequences of dysregulated metabolism, which resulted in an NIH F32 postdoctoral fellowship award in investigating failed vertebral bone formation in mucopolysaccharidoses (MPS) disorders as a consequence of aberrant glycosaminoglycan metabolism. Through this award, Dr. Peck elucidated molecular mechanisms underlying failed bone formation during development in MPS, which has led to large animal model studies assessing potential therapeutic strategies. During her postdoctoral fellowship in the Department of Orthopaedic Surgery at the University of Pennsylvania, Dr. Peck also made important contributions to the field of disc biology by elucidating the transcriptomic profile of early disc development, which has significant implications in addressing the substantial clinical need for treating disc degeneration. Dr. Peck’s overall research interests are to combine her chemistry background with her postdoctoral experience in musculoskeletal biology to investigate carbohydrate-mediated signaling in spine development and homeostasis, to determine how dysfunction in these signals lead to degeneration and diseased states, and to develop biologic and engineering approaches to regenerative therapies for musculoskeletal tissues. In addition to her research activities, Dr. Peck is dedicated to serving the scientific community at large and is a member of the American Society of Bone and Mineral Research Early Stage Investigator subcommittee and is serving as the chair for the 2020 Musculoskeletal Biology and Bioengineering Gordon Research Seminar.
