Geoffrey Craig Tabin, MD
Fairweather Foundation Professor
Bio Dr. Geoff Tabin is Co-Founder and Chairman of the Himalayan Cataract Project and a Professor of Ophthalmology and Global Medicine at Stanford University. He has published more than 45 peer-reviewed articles, two books and a dozen book chapters related to his work in ophthalmology and the developing world.
Dr. Tabin is the fourth person in the world to reach the tallest peak on each of the seven continents. His passion for mountain climbing directed him to his professional career in eye care. After summiting Mt. Everest, on one of his expeditions, he came across a Dutch team performing cataract surgery on a woman who had been needlessly blind for three years. It was then he understood his life calling.
Tabin graduated from Yale University and then earned an MA in Philosophy at Oxford University on a Marshall Scholarship. From there, he took his interest in moral philosophy and health care delivery to Harvard Medical School where he earned his MD in 1985. After completing an ophthalmology residency at Brown University and a fellowship in corneal surgery in Melbourne, Australia, Dr. Tabin returned to Nepal to work with Dr. Sanduk Ruit.
Tabin and Nepalese eye surgeon Dr. Sanduk Ruit established the Himalayan Cataract Project in 1995 – with a vow to work to eliminate all preventable and treatable blindness from the Himalayan region in their lifetime, a goal, in Tabin’s words, “more audacious than setting out to make the first assent of the East Face of Mount Everest.” Dr. Ruit, whom the Associated Press heralded as the “god of sight” to the world’s poor, and Tabin have proven that hospital quality standards can be applied in impoverished areas devoid of electricity and clean water. Their successful approach to restoring sight and dogged perseverance has made possible what 20 years ago seemed impossible.
The Himalayan Cataract Project has since expanded beyond the Himalayas to encompass Sub-Saharan Africa as well. Dr.Tabin spends a considerable part of the year working abroad throughout the Himalayas and Sub-Saharan Africa. At Stanford his practice focus encompasses surgery and treatment of diseases of the anterior and external eye including cataract and corneal surgery.

David Camacho Talavera
Clinical Instructor, Anesthesiology, Perioperative and Pain Medicine
Bio Dr. David Talavera earned his doctoral degree in Clinical Psychology from the University of Houston where he worked in the Culture, Risk, and Reliance Lab. His research focused on examining the impact of race/ethnicity and acculturation in health outcomes and anxiety. His broader interests included developing culturally sensitive interventions for those suffering from chronic illness and pain. Dr. Talavera completed an APA-accredited Psychology Internship at the Cambridge Health Alliance/Harvard Medical school. He primarily worked at the Latino Mental Health Clinic, but also had rotations in Primary Care, the Acute Psychological Services, and the Psychology Emergency Services. It was at these sites where he gained added training in behavioral medicine, culturally competent care, and Spanish-language mental health services. Collectively, for Dr. Talavera, these experiences highlighted the critical role of race, ethnicity, and culture have on an individual’s experience of stress and health. As a result, he aims to incorporate these multicultural factors into his treatment and evaluation.
After internship, in 2019 he completed an APA-accredited Fellowship in Pain Psychology at Stanford University School of Medicine in the Department of Anesthesiology, Division of Pain. Dr. Talavera is currently a Clinical Instructor in the Department of Anesthesia and works in the Stanford Pain Management Center. Dr. Talavera's professional interests include expanding pain psychology treatment modalities for underrepresented groups and Spanish-speaking populations. He aims to expand these services within the Stanford Health Care system and continue to teach/supervise on multicultural factors within pain psychology.
