Lisa A. Orloff, MD, FACS, FACE
Professor of Otolaryngology - Head & Neck Surgery (OHNS)
On Partial Leave from 03/02/2026 To 03/31/2026BioLisa A. Orloff, MD, FACS, FACE, is Director of the Endocrine Head & Neck Surgery Program and Professor in the Department of Otolaryngology — Head & Neck Surgery, Division of Head & Neck Surgery, at Stanford University School of Medicine. She is Director of the Stanford Thyroid Tumor Program within the Stanford Cancer Center. Her clinical practice focuses on the surgical management of thyroid and parathyroid tumors and disorders.
Dr. Orloff is an internationally recognized leader in the field of endocrine head and neck surgery. She is also an expert in the application of ultrasonography to the diagnosis and management of diseases of the head and neck, with an emphasis on thyroid cancer. Dr. Orloff performs minimally invasive ultrasound-guided procedures such as radiofrequency ablation for the nonsurgical management of appropriate thyroid pathology. Her background in microvascular and laryngeal surgical techniques lends a unique level of refinement to her endocrine surgical practice. A major component of her clinical work is the management of persistent or recurrent thyroid cancer. Dr. Orloff’s multidisciplinary approach to the management of endocrine head and neck disease involves collaboration with her colleagues in other specialties at Stanford and throughout the country. Dr. Orloff also studies the regeneration of tissue that has been lost as a result of cancer therapies.
Dr. Orloff received her bachelor’s degree at Stanford, and her medical degree from the University of California, Los Angeles. She completed her residency in Otolaryngology — Head & Neck Surgery at the University of Washington and a visiting fellowship in Microvascular & Reconstructive Surgery at Mount Sinai Medical Center in New York. Prior to joining the faculty at Stanford, she was the Robert K. Werbe Distinguished Professor in Head & Neck Cancer, and Chief of the Division of Head & Neck Surgery at the University of California, San Francisco (UCSF.)
Dr. Orloff served three consecutive terms as the Chair of the American Academy of Otolaryngology — Head & Neck Surgery (AAO-HNS) Endocrine Surgery committee, and served for many years as a voting member of the FDA’s Panel to evaluate medical devices for Otolaryngology. She holds leadership roles within the American Head and Neck Society, the American Thyroid Association, the American Institute of Ultrasound in Medicine, and the American College of Surgeons. She is co-chair of the ACS Thyroid, Parathyroid, and Neck Ultrasound training program and a member of the ACS National Ultrasound Faculty executive board. She is also a member of such influential teams as the National Cancer Institute (NCI) steering committee on Thyroid Cancer Clinical Trials and the Endocrine Surgery Committee of the American Association of Clinical Endocrinology (AACE). She authored the leading textbook, Head and Neck Ultrasonography (Plural Publishing), as a reference for clinicians; the second edition was published in 2017. Dr. Orloff is a former Fulbright scholar. -
Anthony Oro, MD, PhD
Eugene and Gloria Bauer Professor
Current Research and Scholarly InterestsOur lab uses the skin to answer questions about epithelial stem cell biology, differentiation and carcinogenesis using genomics, genetics, and cell biological techniques. We have studied how hedgehog signaling regulates regeneration and skin cancer, and how tumors evolve to develop resistance. We study the mechanisms of early human skin development using human embryonic stem cells. These fundamentals studies provide a greater understanding of epithelial biology and novel disease therapeutics.

Franklin M. ("Lynn") Orr, Jr.
Keleen and Carlton Beal Professor in Petroleum Engineering, Emeritus
Current Research and Scholarly InterestsResearch
My students and I work to understand the physical mechanisms that control flow of multiphase, multicomponent fluids in the subsurface, using a combination of experiments and theory. The theory part includes numerical simulation of flow in heterogeneous porous rocks and coalbeds, often using streamline approaches, and it also involves solving by analytical methods the differential equations that describe the interactions of complex phase equilibrium and flow (porous rocks containing more than one flowing phase can sometimes act like a chromatograph, separating components as they flow). The experiments are used to test how well the models describe reality. Applications of this work range from enhanced oil and gas recovery to geologic storage of carbon dioxide (to reduce greenhouse gas emissions) to the transport of contaminants in aquifers.
Teaching
I teach a courses for graduate students on the mathematics of multiphase, multicomponent flow in porous media and on the thermodynamics of phase behavior. I also teach an undergraduate course on energy for freshmen.
