Biography


Dr. Ko joined Stanford Medicine in 2012 and serves as Director and Chief of Medical Dermatology for Stanford Health Care (SHC) while also spearheading the dermatology department's efforts around network development, digital health, quality/safety/performance improvement, and value-based care. He is active in a number of leadership roles within the organization including co-chairing the Clinic Advisory Council, a forum of medical and executive leaders of Stanford Health Care’s Ambulatory clinics, and as a Service Medical Director.

His passion for melanoma, early cancer detection, and improving care delivery drives his efforts and research around leveraging advances in machine learning and artifical intelligence to increase the breadth of populations that can be reached. He developed and runs a digital care delivery program at SHC, providing virtual visits for patients and remote consultations for referring clinicians. He conducts research on and engages in collaborations around interventions that layer advances in machine learning on digital health capabilities to enhance access, quality and value of dermatologic care. He chairs the American Academy of Dermatology's Task Force Committee on Augmented Intelligence.

Dr. Ko has also been driven to find new treatments for alopecia areata, an immune-mediated condition that can progress to total hair loss through various clinical trials and translational research efforts. He sits on the clinical research advisory board of the National Alopecia Areata Foundation and is founder and co-director of the Skin Innovation and Interventional Research Group (SIIRG) which conducts clinical and translational research on skin disease.

He graduated magna cum laude from Harvard University and worked in investment banking; mergers and acquisitions at JP Morgan before going on to earn a combined medical and business degree at Tufts University. During medical school, he was a member of the Alpha Omega Alpha honor society. Dr. Ko then performed his residency at the Harvard Dermatology Residency Training Program where he served as chief resident.

Dr. Justin Meng Ko is absolutely the very best doctor! He is always very caring, considerate, attentive, detailed, kind and professional. On this last visit especially, he went above and beyond any expectations and the call of duty. I was delayed at another appointment prior to my visit with him. I called the clinic to apprise them of my delay. Dr. Ko stayed past the normal clinic time to see me. He spent a long amount of time to address my problems in detail with patience and kindness. He even addressed and asked about my wife's well-being in taking care of me and asked her if he could render help to her in any way! He really cares about my problems and always gives me sound advise. He always follows up and asks how I have been doing. He is truly marvellous and a genuinely caring physician and a great human being. I wish we could clone Dr. Ko. Others should learn from him and strive to reach his standards. My wife and I feel very lucky and blessed to have Dr. Ko as our physician. He should be greatly rewarded and highly commended for his excellent care and attention to his patients!
