  • Matthew P. Scott

    Matthew P. Scott

    Professor of Developmental Biology, Emeritus

    Current Research and Scholarly Interests Our research has been focused on the genetic regulation of animal development and its relation to birth defects, cancer, and neurodegeneration. We studied mechanisms and functions of Hedgehog (Hh) signaling, which controls cell fates and growth, in the context of normal development and brain cancer. We studied a neurodegenerative disease, Niemann-Pick C syndrome, that affects intracellular organelle movements and sterol homeostasis. Due to Dr. Scott's new job, the lab is no longer active.

  • Vittorio Sebastiano

    Vittorio Sebastiano

    Assistant Professor (Research) of Obstetrics and Gynecology (Reproductive and Stem Cell Biology)

    Current Research and Scholarly Interests The thread of Ariadne that connects germ cells, preimplatation development and pluripotent stem cells is the focus of my research, with a specific interest in human development. My long-term goals are: 1. Understanding the biology of germ cells and and their ability to sustain early preimplantation development; 2. Understanding the mechanisms that regulate very early cell fate decisions in human embryos; 3. Understanding the biology of derivation and maintenance of Pluripotent Stem Cells

    Clinical Assistant Professor, Medicine - General Medical Disciplines

    Current Research and Scholarly Interests Interested in complementary/alternative medicine, international health, international adoption medicine and providing full spectrum health care.

  • George Segall

    George Segall

    Professor of Radiology (Nuclear Medicine) and, by courtesy, of Medicine (Cardiovascular) at the Palo Alto Veterans Administration Health Care System

    Current Research and Scholarly Interests Scintigraphic evaluation of coronary blood flow and myocardial function using single photon emission computed tomography (SPECT) and positron emission tomography (PET). Tumor imaging and characterization of pulmonary nodules with PET/CT.

  • Elif Seda Selamet Tierney

  • Subhro K. Sen, MD

    Subhro K. Sen, MD

    Clinical Assistant Professor, Surgery - Plastic & Reconstructive Surgery

    Bio Subhro K. Sen, MD, Clinical Assistant 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 peripheral nerve research fellowship at the Washington University School of Medicine in St. Louis. He received his postgraduate training in general surgery at Indiana University, followed by plastic and reconstructive surgery at Johns Hopkins University. He completed 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 plastic surgery 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 also co-medical director of the Stanford Advanced Wound Care Center. As a hand surgeon in the Robert A. Chase Hand and Upper Limb Center, he has interests in hand trauma, reconstruction, degenerative conditions, peripheral nerve injuries, oncologic conditions and congenital hand differences.

    In addition to his clinical practice, Dr. Sen is involved in research, publication, and teaching. His peer-reviewed research includes studies on peripheral nerve regeneration, and he has authored a number of book chapters on a variety of hand surgery topics. He has reviewed manuscripts submitted for publication in Plastic and Reconstructive Surgery and Annals of Plastic Surgery. Dr. Sen is double board certified by the American Board of Plastic Surgery and the American Board of Surgery. He is a member of the American Society of Plastic Surgeons, American Society for Reconstructive Microsurgery and the American Society for Surgery of the Hand.

  • Sharon Sha, MD, MS

    Sharon Sha, MD, MS

    Clinical Assistant Professor, Neurology & Neurological Sciences

    Bio Dr. Sha received her Bachelor’s degrees from UC Berkeley in Cognitive Science and Molecular Cell Biology, emphasizing in Neurobiology. She went on to obtain a Master’s degree in Physiology and MD from Georgetown University. She trained in Neurology at UCLA and Stanford University, and completed a clinical and research fellowship in Behavioral Neurology at UCSF, where she focused on identifying biomarkers for genetic forms of frontotemporal dementia and caring for patients with movement disorders and cognitive impairment.

    While at UCSF, she saw the majority of patients with Huntington’s disease and ataxia in clinic and research, including ENROLL HD and the Natural History Study of and Genetic Modifiers in Spinocerebellar Ataxias. She has been a member of the Hungtington’s Study Group since 2011. She is board-certified in Neurology by the American Board of Psychiatry and Neurology and subspecialty boarded in Behavioral Neurology and Neuropsychiatry by the United Council for Neurologic Subspecialties.

    Dr. Sha’s clinical expertise include Alzheimer’s disease, frontotemporal dementia, Lewy Body disease, corticobasal syndrome, progressive supranuclear palsy, Huntington’s disease, ataxia, multiple system atrophy, and other dementias.

    Dr. Sha’s non-clinical time is spent conducting clinical trials in order to identify disease modifying treatments for dementia. She has a special interest in genetic forms of dementia and the cognitive impairment in Parkinsonian-related disorders.
