Faculty Information


Dr. Moshiri is a board-certified dermatologist and dermatopathologist specializing in skin oncology, complex medical dermatology, and diagnostically challenging cases where his training in both disciplines is critical to clinical-pathologic correlation. He has special interests in melanoma and pigmented lesions, and using the latest technologies and techniques to diagnose, monitor and treat these growths. He currently maintains a pigmented lesion specialty clinic at UWMC Roosevelt, as well as a melanoma clinic at the Seattle Cancer Care Alliance (SCCA) where he treats advanced melanoma with injectable oncolytic viral therapy.

Dr. Moshiri’s research interests include studying the immune system’s response to cancer at the cellular level and how that may predict outcomes of cancer therapy. He is also passionate about medical education and regularly lectures to medical students, residents and peers.
