Mahua Dey, MD


Mahua Dey, MD, is a neurosurgeon at UW Health and an assistant professor of neurological surgery and director of the surgical neuro-oncology program at the University of Wisconsin School of Medicine and Public health. She specializes in surgical management of both non-cancerous (benign) and cancerous (malignant) brain and spinal cord tumors.

Dr. Dey has a special interest in malignant brain tumors involving eloquent areas of the brain which require awake and function mapping, stereotactic radiosurgery and minimally invasive brain surgery. During awake brain surgery Dr. Dey uses imaging tools to work around and minimize impacts on areas of the brain that are critical for key body functions.

Connecting with others is what drew Dr. Dey to a career in medicine. She enjoys getting to know people at a personal level and takes pride in treating patients as she would her own family.

Dr. Dey leads an active research program and is funded by the National Institutes of Health to develop specialized treatments, including vaccine-based therapies for malignant brain tumors.

In her spare time, Dr. Dey enjoys painting, cooking, scuba diving and spending time with family.

A brain tumor diagnosis changes your life. Even if it is benign, it's a life-altering diagnosis. We help people when they need us the most — when they're facing their most difficult challenge. There's nothing more gratifying than to be able to give patients quality time back that they can spend with their family and their loved ones.
