  • Paul A. Khavari, MD, PhD

    Paul A. Khavari, MD, PhD

    Carl J. Herzog Professor of Dermatology in the School of Medicine

    Current Research and Scholarly InterestsWe work in epithelial tissue as a model system to study stem cell biology, cancer and new molecular therapeutics. Epithelia cover external and internal body surfaces and undergo constant self-renewal while responding to diverse environmental stimuli. Epithelial homeostasis precisely balances stem cell-sustained proliferation and differentiation-associated cell death, a balance which is lost in many human diseases, including cancer, 90% of which arise in epithelial tissues.

  • Sarita Khemani

    Sarita Khemani

    Clinical Associate Professor, Medicine

    BioDr. Sarita Khemani is a Clinical Associate Professor of Medicine at Stanford University School of Medicine, a Hospital Medicine physician, and the founding Director of STRIVE, the Stanford Resilience & Longevity Initiative.

    Her academic work focuses on physiological reserve as a central concept in longevity medicine — the biological capacity that allows individuals to maintain strength, cognition, independence, and recovery potential across the lifespan. Through Stanford STRIVE, she is advancing a clinically grounded approach to measuring and strengthening resilience across aging, illness, hospitalization, surgery, and recovery.

    Dr. Khemani’s clinical expertise is in perioperative medicine and the care of neurosurgical patients, with a focus on preventing and managing medical complications around surgery. This work has shaped a central question in her academic work: why do some individuals recover well after surgery, illness, or biological stress, while others experience accelerated functional decline?

    A dedicated educator, Dr. Khemani has served as Director of the Perioperative Medicine Rotation for medical students, Stanford Medicine residents and physician assistant students. She is a recipient of the Department of Medicine’s Excellence in Teaching Award.

    Dr. Khemani is the founder and co-director of the Stanford Medicine Clinical Summer Internship (SMCSI), a globally recognized program that exposes premedical students to the clinical and academic world of medicine. Under her leadership, the inclusive program has expanded access to medical training through numerous scholarships for students representing a range of experiences, with a mission to empower future leaders in healthcare.

    Dr. Khemani is an invited speaker at national and international medical meetings, has presented at Stanford Neurosurgery Grand Rounds, and delivered the keynote address at the Stanford Physician Assistant Program’s graduation ceremony. She has also been featured on U.S. media platforms and international television as a guest expert.

    Dr. Khemani is a member of the American College of Physicians and serves on the Stanford Hospital Pharmacy and Therapeutics Committee and the Hospital Medicine Wellness Committee.

  • Cynthia Khoo

    Cynthia Khoo

    Clinical Associate Professor, Anesthesiology, Perioperative and Pain Medicine

    BioDr. Khoo serves as the Associate Program Director of Career Development for the Stanford Anesthesia Residency and Co-Director of the Division of Global Health Equity. In her residency role, she leads the Anesthesiology Leadership Pathways at Stanford (ALPS), a comprehensive mentorship initiative spanning advocacy, research, community engagement, global health, innovation, medical education and quality improvement.

    A graduate of the University of Pennsylvania’s MD-PhD program, Dr. Khoo completed her residency and regional anesthesia fellowship at Stanford. Her global health work focuses on promoting safe, equitable perioperative care through high-tech education, including immersive reality simulations for crisis management in Tanzania and Guyana. She supports bi-directional partnerships that facilitate resident rotations and host international scholars at Stanford. Her current research focuses on enhancing clinical research quality in low-resource settings across Rwanda, Vietnam, Guyana, and Tanzania. Dr. Khoo specializes clinically in regional, orthopedic, and thoracic anesthesia.

  • Chaitan Khosla

    Chaitan Khosla

    Wells H. Rauser and Harold M. Petiprin Professor and Professor of Chemistry and, by courtesy, of Biochemistry

    Current Research and Scholarly InterestsResearch in this laboratory focuses on problems where deep insights into enzymology and metabolism can be harnessed to improve human health.

    For the past two decades, we have studied and engineered enzymatic assembly lines called polyketide synthases that catalyze the biosynthesis of structurally complex and medicinally fascinating antibiotics in bacteria. An example of such an assembly line is found in the erythromycin biosynthetic pathway. Our current focus is on understanding the structure and mechanism of this polyketide synthase. At the same time, we are developing methods to decode the vast and growing number of orphan polyketide assembly lines in the sequence databases.

    For more than a decade, we have also investigated the pathogenesis of celiac disease, an autoimmune disorder of the small intestine, with the goal of discovering therapies and related management tools for this widespread but overlooked disease. Ongoing efforts focus on understanding the pivotal role of transglutaminase 2 in triggering the inflammatory response to dietary gluten in the celiac intestine.

  • Nitasha Khullar, MD

    Nitasha Khullar, MD

    Clinical Assistant Professor, Medicine - Immunology & Rheumatology

    BioDr. Nitasha Khullar is a board-certified, fellowship-trained rheumatologist at Stanford Health Care. She is also a clinical assistant professor in the Department of Medicine, Division of Immunology and Rheumatology at Stanford University School of Medicine.

    Dr. Khullar specializes in caring for people with autoimmune and inflammatory diseases that affect the joints, muscles, and immune system. She treats conditions like lupus, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, vasculitis, gout and other complex rheumatic disorders. She provides personalized care for each patient, focusing on early diagnosis and working closely with other medical specialists to help manage these diseases. She values shared decision-making and a patient-centric approach to her care.


    Dr. Khullar’s work has been presented at national and international conferences, including the American College of Rheumatology and the American Association of Immunology. She has authored peer-reviewed publications in journals such as Viruses, Molecular Neurobiology, Age (Dordrecht, Netherlands), and Current Treatment Options in Rheumatology.

    She is a member of the American College of Rheumatology.
