Assistant Professor of Medicine

Dr. Mazi’s research/interest focuses is on fungal infections, mentored by Drs. Andrej Spec and Bill Powderly, as well as clinical outcomes/clinical trials mentored by Drs. Rachel Presti and Jane O’Halloran. Highlights of his fellowship training so far include: [publications, poster presentations, speaking engagements, involvement in active trials, etc – free form].

I chose WUSM for fellowship training because the fellowship program adapts and changes to fit the goals of the fellows. Whether that be academic research, medical education, private practice, or public health and policy, WashU makes an individual path for each fellow to be successful at what they are passionate about. My favorite things to do in St. Louis involve food, drinks, and live music. The pandemic has limited these activities; luckily St Louis boasts some of the best parks in the country (Forest Park, Tower Grove Park). Lastly there are many things around town that are amazing to visit like the St Louis Art Museum, Natural History Museum, Science Museum, and the Zoo—all of which are free to visit!
