About me

Dr. Wei Ai is a blood cancer specialist who cares for adults with conditions such as Hodgkin's lymphoma and non-Hodgkin's lymphoma, including cutaneous lymphomas, which primarily involve the skin. She also sees patients needing blood and bone marrow transplantation.

In her research, Ai focuses on novel approaches to lymphoma treatment, especially targeted agents for T-cell lymphomas. Her studies often lead to clinical trials of new therapies that target cancer at the molecular level.

Ai earned a doctoral degree in microbiology and immunology as well as her medical degree from Stanford University School of Medicine. She completed a residency in internal medicine at UCSF, followed by fellowship training in medical oncology at Stanford.
