Dr Fung

Maxwell A. Fung, M.D. (Director) is Board-certified in Dermatology and Dermatopathology and has been engaged in the full-time practice of academic medicine as an attending physician for 18 years. Dr. Fung wears two patient care hats: one as a dermatopathologist who interprets skin biopsy specimens, and one as a dermatologist evaluating patients at the bedside (currently by physician-to-physician consultation only). His clinical interests include the evaluation and management of stubborn itchy rashes that elude conventional classification. His original research focuses on ways to improve diagnostic accuracy and communication between practicing dermatologists and dermatopathologists in ways that are practical and of immediate clinical relevance (see eosinophils, alopecia, dermal hypersensitivity, epidermotropism versus exocytosis, caterpillar bodies, dysplastic nevus). Dr. Fung also enjoys collaborating with world-class scientists for basic research endeavors (see galectin-3, comparative transcriptomics, microparticles).

Dr. Fung was born and raised in Sacramento, a graduate of John F. Kennedy Sr. High School. After completing undergraduate studies at Stanford University and medical school at University of California San Francisco, he completed an internship in Internal Medicine at Beth Israel Hospital, Boston, Massachusetts. Dermatology residency training and chief residency were served at UC San Francisco, followed by dermatopathology fellowship training at Cornell University Medical Center under the direction of N. Scott McNutt, MD.

From 1998 to 2002, Dr. Fung was Assistant Professor at the University of Connecticut School of Medicine, attending the Dermatopathology Service and Dermatology Clinics. During this time, he also directed the Multi-Disciplinary Cutaneous Lymphoma Clinic. Joining UC Davis in 2002, Dr. Fung received a 2003 Award for Excellence and Dedication in Teaching from the UC Davis Department of Dermatology. In 2005, Dr. Fung was elected into the Alpha Omega Alpha Honor Medical Society and served as President of the Sacramento Valley Dermatology Society.

Dr. Fung has served as Associate Professor (2006-2012) and, as of 2012, Professor of Clinical Dermatology & Pathology at UC Davis. Dr. Fung is the founding and current Director of the UC Davis Dermatopathology Service, also serving as its CLIA Medical Director. Regionally, Dr. Fung is a dermatopathology consultant for the Sacramento Valley Dermatology Society and enjoys attending local journal club meetings. Dr. Fung received the Outstanding Faculty Member Award from the UC Davis Department of Dermatology (2006, 2011) and the Faculty Teaching Award from the UC Davis Department of Pathology & Laboratory Medicine (2006). Dr. Fung is also Vice Chair for Academic Personnel and recently served as the first Mentoring Director (UC Davis Health System Mentoring Academy) in the Dermatology Department at UC Davis.

Dr. Fung is a member of two Editorial Boards: Journal of Cutaneous Pathology and Dermatology Online Journal, and is a Faculty Member of F1000 Medicine (Dermatologic Pathology Section, f1000medicine.com). Dr. Fung serves as a Vice Chair for the Dermatology Foundation and serves on the Test Development and Advisory Committee for the American Board of Pathology (Dermatopathology). Dr. Fung has also served on the Board of Directors (Member-At-Large) of the American Society of Dermatopathology and two terms as a Member of the Executive Committee of the International Society of Dermatopathology.  Dr. Fung also enjoys lecturing, including the meetings of the American Academy of Dermatology, American Society of Dermatopathology, International Society of Dermatopathology, College of American Pathologists, and Board Review courses. Dr. Fung has authored or co-authored over 80 original manuscripts and textbook chapters. He enjoys playing tennis, mountain biking, the piano, attending Sacramento Kings games, and spending time with his wife and children.
