Gary K. Roberts, D.D.S.
Clinical Assistant Professor, Surgery - Plastic & Reconstructive Surgery
BioDr. Roberts has performed hospital dentistry and surgery at Stanford University Medical Center and Lucile Packard Children's Hospital since 1995. He is also on the faculty at University of the Pacific School of Dentistry. He treats a variety of oral and maxillofacial conditions, including dental trauma and infection, dental implant and restorative reconstruction, surgical tooth extraction, bone and tissue grafting, conventional and surgical endodontic procedures, dental oncology care of cancer patients, as well as orofacial pain treatment.
He has presented CME lectures and Grand Rounds to numerous Departments at Stanford, as well as teaching Residents and Fellows at Stanford Medical School and the Palo Alto VA. He also lectures in the Physician Assistant Program at Stanford.
During his nearly a quarter of a century of military service, he was one of the leading researchers on combat trauma and the pathophysiology of projectile wounds. He currently serves as a member of the Council on Peer with the California Dental Association and is an Anesthesia Evaluator for the California State Dental Board. Dr. Roberts is frequently asked to speak on a variety of topics to organizations both in the US and internationally. -
Brian Ruhle, MD, MS
Clinical Assistant Professor, Surgery - General Surgery
BioDr. Brian Ruhle is a board-certified surgeon with dual-fellowship training in minimally invasive bariatric (weight loss) surgery and endocrine surgery. He is also a clinical assistant professor in the Department of Surgery, Division of General Surgery at Stanford University School of Medicine.
Dr. Ruhle specializes in bariatric surgery, foregut (upper digestive tract) surgery, adrenal surgery, and abdominal wall reconstruction. He uses leading-edge laparoscopic and robotic surgical techniques to help patients achieve sustainable weight loss and improve obesity-related health conditions. His expertise in advanced minimally invasive procedures offers patients significant benefits, including faster recoveries, reduced pain, and shorter hospital stays.
Dr. Ruhle’s research interests span a wide range of topics in metabolic and bariatric surgery. His studies have explored combination therapies for managing obesity, improvements in screening and treating endocrine disorders, and optimizing outcomes in thyroid and parathyroid surgeries. He has published his findings in many peer-reviewed journals, including Surgery, Journal of Gastrointestinal Surgery, and Journal of the American College of Surgeons.
Dr. Ruhle has presented at prominent national conferences, including the annual meetings of the American Association of Endocrine Surgeons and the American College of Surgeons Clinical Congress. His presentations have discussed using GLP-1 receptor agonists (weight loss medications that help regulate blood sugar and reduce appetite) before and after bariatric surgery. He has also addressed improving screening protocols for hyperaldosteronism (high blood pressure caused by excess production of the hormone aldosterone by the adrenal gland).
Dr. Ruhle is a member of the American Association of Endocrine Surgeons, the American Society for Metabolic and Bariatric Surgery, and the Society of American Gastrointestinal and Endoscopic Surgeons. -
Nazish Sayed MD, PhD
Associate Professor (Research) of Surgery (Vascular Surgery)
Current Research and Scholarly InterestsThe Sayed Laboratory investigates how endothelial dysfunction contributes to cardiovascular disease and leverages human stem cell technologies to identify novel therapeutic strategies. Our research integrates patient-derived induced pluripotent stem cells (iPSCs), engineered cardiac tissues, organoids, human biospecimens, and multi-omic technologies to uncover mechanisms underlying inherited and acquired cardiovascular diseases.
A major focus of the laboratory is understanding endothelial–cardiomyocyte communication in cardiomyopathy. Using patient-specific iPSCs, human cardiac organoids, engineered heart tissues, spatial transcriptomics, and single-cell multi-omics, we study how endothelial dysfunction drives myocardial fibrosis, inflammation, and heart failure. Current efforts include investigations into LMNA-related dilated cardiomyopathy, endothelial-to-mesenchymal transition (EndoMT), and mechanisms of fibrotic remodeling.
A second major area of research is cardio-oncology. The laboratory develops human disease models to understand cardiovascular complications associated with cancer therapies, including tyrosine kinase inhibitors and immune checkpoint inhibitors. These studies have identified novel vascular mechanisms underlying treatment-related hypertension, cardiomyopathy, and heart failure.
The laboratory also investigates cardiovascular aging, toxic environmental exposures, rare vascular diseases, and regenerative medicine. By integrating human tissues, advanced stem cell models, genome engineering, spatial biology, and artificial intelligence–enabled multi-omic analyses, our goal is to develop precision therapeutic strategies that improve cardiovascular health and patient outcomes. -

Carolyn Dacey Seib, MD, MAS
Associate Professor of Surgery (General Surgery)
BioDr. Carolyn Dacey Seib is a fellowship-trained endocrine surgeon and board-certified general surgeon who specializes in surgery of the thyroid, parathyroid, and adrenal glands. In 2025, she was among the first surgeons in the United States to earn a Focused Practice Designation in Complex Thyroid and Parathyroid Surgery from the American Board of Surgery, reflecting her expertise in these procedures and related patient management.
Dr. Seib provides comprehensive and personalized care for patients with thyroid, parathyroid, and adrenal disorders, including thyroid cancer, hyperthyroidism, primary hyperparathyroidism, primary aldosteronism, autonomous cortisol secretion, and pheochromocytomas. Her approach combines advanced surgical techniques with a focus on patient-centered outcomes, ensuring that each treatment plan is tailored to the individual.
In addition to her clinical practice, Dr. Seib is an NIH-funded researcher whose work focuses on optimizing surgical decision-making and outcomes for patients with endocrine disorders. She has received research support from the National Institute on Aging and the American Thyroid Association, and her studies have been published in leading peer-reviewed journals and featured in national media, including The New York Times.
Dr. Seib completed her undergraduate education at Princeton University (summa cum laude), earned her medical degree from the New York University School of Medicine, and completed her general surgery residency and endocrine surgery fellowship at the University of California, San Francisco (UCSF). -
Subhro K. Sen, MD
Clinical Associate Professor, Surgery - Plastic & Reconstructive Surgery
BioSubhro K. Sen, MD, Clinical Associate Professor in the Division of Plastic and Reconstructive Surgery, graduated from Northwestern University with a degree in biomedical engineering. He went on to receive his medical degree from the Northwestern University Feinberg School of Medicine. After medical school, he completed a yearlong peripheral nerve research fellowship under Dr. Susan Mackinnon at the Washington University School of Medicine in St. Louis. He completed his postgraduate training in general surgery at Indiana University, followed by plastic and reconstructive surgery at Johns Hopkins University. He finished his training with a hand and upper extremity surgery fellowship at Stanford University.
Dr. Sen’s general clinical interests are in reconstructive surgery, microvascular surgery, and hand and upper extremity surgery. His practice includes: post-traumatic extremity reconstruction; post-oncologic reconstruction of the head and neck, trunk and extremities; perforator flap surgery; and melanoma surgery. He is medical director of the Advanced Wound Care Center at Stanford Health Care. As a hand surgeon in the Robert A. Chase Hand and Upper Limb Center, he has interests in hand trauma, degenerative conditions, peripheral nerve injuries, and complex upper extremity flap reconstruction.
In addition to his clinical practice, Dr. Sen is involved in research, publication, and teaching. His peer-reviewed research includes studies on extremity reconstruction, peripheral nerve regeneration, and he has authored a number of book chapters on a variety of plastic and hand surgery topics.
