Thomas Kremen, MD, began participating in basic science research while obtaining his undergraduate degree in molecular, cellular and developmental biology. He continued this work after graduating from the University of California, Santa Barbara, where he worked in the field of neuro-oncology; his translational research aimed at treating malignant brain tumors by activating the body's own dendritic cells. While in orthopedic surgery residency, he continued his research efforts and completed a yearlong research fellowship through the California Institute of Regenerative Medicine. As a research fellow, he worked to characterize strategies to better direct the differentiation of mesenchymal stem cells in order to improve the healing of long-bone fractures. At Cedars-Sinai, Kremen and his collaborators in the laboratory of Dan Gazit, PhD, DMD, work to enhance the body's own stem cells to improve healing of shoulder and knee pathology. Additionally, Kremen is a researcher in the biomechanics of shoulder and knee reconstruction in collaboration with Melodie Metzger, PhD, director of the Cedars-Sinai Biomechanics Laboratory. In March 2015, Kremen was awarded the Young Investigators Grant from the American Orthopaedic Society for Sports Medicine for his proposal aiming to characterize and optimize the use of stem cells in healing tendon injuries. Also in March 2015, he was awarded a New Investigator Grant from the Orthopaedic Research and Education Foundation in order to improve understanding of the biomechanics of anterior cruciate ligament reconstructions.
