Michael T. Longaker, MD, MBA, DSc (hon), FACS

As a world-renowned pediatric craniofacial surgeon, research scientist, and co-director of the Stanford Institute for Stem Cell Biology & Regenerative Medicine, Dr. Michael Longaker is accustomed to being on the razor’s edge of stem cell science. He has dedicated years of research to tissue repair, replacement, and regeneration, harnessing the power of stem cells—leading to more than 1,200 peer-reviewed publications. Dr. Longaker is a global leader and role model for physicians and scientists who aspire to improve patient care through research into regenerative medicine.

Dr. Longaker attended Michigan State where he played varsity basketball, winning 2 Big Ten titles and the national championship in 1979 with Earvin “Magic” Johnson, and graduated with highest honors. He went on to Harvard Medical School and then completed his surgery training at UCSF where he met his mentor, pediatric surgeon Dr. Michael Harrison, a pioneer in the field of fetal surgery. It was during this time that Dr. Longaker’s interest in tissue repair and regenerative medicine was ignited by the observation that fetuses heal without scarring. Dr. Longaker continued his education with training in plastic surgery at NYU and later in craniofacial surgery at UCLA. He then earned his MBA in 2003 from the University of California, Berkeley and Columbia University in the inaugural class of their combined program.

He is a member of the American Society for Clinical Investigation, the Association of American Physicians, and he is one of the rare surgeons elected into the National Academy of Medicine (NAM). Dr. Longaker has received multiple awards, including the Sheen Award from the American College of Surgeons, the Jacobson Award, and the Flance-Karl Award from the American Surgical Association.

Dr. Longaker currently holds the following positions at Stanford University School of Medicine/Lucile Salter Packard Children’s Hospital

  • Deane P. and Louise Mitchell Professor and Vice Chair
  • Co-Director, Stanford Institute for Stem Cell Biology and Regenerative Medicine
  • Director, Children’s Surgical Research

Ophir Klein, MD, PhD

Dr. Klein is the Hillblom Distinguished Professor in Craniofacial Anomalies and the Epstein Professor of Human Genetics at the University of California, San Francisco (UCSF). He is a specialist in pediatric medical genetics with unique expertise in craniofacial and dental anomalies and genetic disorders. He brings years of research in craniofacial and tooth developmental biology and adult stem cell biology to Stemodontics, and his work in these fields has been featured in over 150 publications. Dr. Klein attended UC Berkeley as an undergraduate and received a PhD in Genetics and an MD from Yale University. He completed a residency at Yale in Pediatrics, and his interest in developmental and regenerative processes led him to complete a genetics residency at UCSF. Dr. Klein is a professor at UCSF, where his research is focused on understanding how organs form in the embryo and how they regenerate in the adult, with a particular emphasis on understanding how stem cells in teeth enable renewal and regeneration.

Dr. Klein has received several honors, including a New Innovator Award from the NIH, the E. Mead Johnson Award from the Society for Pediatric Research, and the Craniofacial Biology Distinguished Scientist Award from the International Association for Dental Research. Dr. Klein was elected to the National Academy of Medicine and the American Society for Clinical Investigation, and he is a Fellow of the American Association for the Advancement of Science.


Christopher Daniel, DDS, MD, FACS

Dr. Daniel brings over a decade of oral and maxillofacial surgery experience to Stemodontics. His dual degree in medicine and dentistry provides our team with a wealth of expertise in both fields, bridging the gap between the stem cell source and future stem cell applications.
