A pioneer in both the development and use of lasers to treat skin diseases and disorders, Dr. Oon Tian Tan is the Director of the Carolyn and Peter Lunch Center for Laser and Reconstructive Surgery at Mass. Eye and Ear. She completed medical school at the Royal Free Hospital School of Medicine at London University, where she also completed her surgical internship year and residency in dermatology. Subsequently, she completed fellowship training in dermatology at Mass General Hospital/Harvard Medical School and later received her Ph.D. from the University of Amsterdam. 

After spending two decades in private practice, Dr. Tan joined Mass. Eye and Ear in 2010, bringing her wealth of experience in dermatological conditions and treatments. Today, she utilizes an array of lasers to treat birthmarks including hemangioma, portwine stains, and café au lait, as well as other benign cutaneous pigmented lesions, warts, tattoos, and scars. 

Throughout her career, Dr. Tan has seen many achievements, including her collaboration on a vascular-specific laser targeting red blood cells and the development of a laser to remove tattoos. She joins annual mission trips to Latin America to care for underserved pediatric patients and was responsible for bringing the first laser to a Quito, Ecuador hospital. 

Dr. Tan’s research interests include laser/tissue interaction, imaging systems for differentiation of normal and abnormal tissues, monitoring response of benign cutaneous vascular tumors to laser treatments, evaluation of non-invasive techniques for measuring cutaneous blood flow to be applied to the measurement of vasoactive drug responses in peripheral vascular disease, treatment of facial flushing, hypertrophic scars, and the treatment and prevention of leg ulcers. Her research also focuses on the basic science of vascular anomalies, especially port-wine stains and their aetiology, including their genetic origin.
