Marshall Diven, MD, MS

Marshall Diven, MD, MS

Chief Resident

I grew up in South Carolina and attended Wofford College where I obtained my Bachelor of Science degree in Biology. I then obtained a master’s degree in biomedical sciences with an emphasis in Immunology and Microbiology from the Medical University of South Carolina School of Graduate Studies. I then earned my Doctorate in Medicine from the University of South Carolina School of Medicine-Greenville in Greenville, SC. After completing my transitional year in Georgia I moved here to Brooklyn for residency. My research has mainly focused on prostate cancer though I am also interested in the interplay of radiation therapy and the immune system. In my spare time I enjoy hiking, skiing, golfing, fishing and eating at new restaurants.

Joy Ogunmuyiwa, MD, MPH

Joy Ogunmuyiwa, MD, MPH

Chief Resident

I am a Dallas, Texas native and my family hails from Nigeria. I earned my undergraduate degree from Duke University where I studied biology and global health. I received my medical degree from Northeast Ohio Medical University. Prior to residency, I completed my Masters in Public Health at Harvard University where my work focused on the social and behavioral determinants of health, the widening inequality within the global health architecture, and designing equitable responses in global health challenges.

My research interests are primarily in health disparities and treatment outcomes, access to tertiary healthcare in low-income and resource-poor settings, as well as the design, implementation, and review of evidence-based health systems and interventions.

I happily serve on the executive board of the Society of Women in Radiation Oncology (SWRO) as the Diversity, Equity, and Inclusion chair. In my spare time, I enjoy photography, traveling, exploring NYC, and spending time with friends and family.

Sana Siddiqui, MD

Sana Siddiqui, MD

I grew up in India and immigrated with my family to the US when I was 12 years old. I attended Cornell University for my undergraduate degree before joining St. George’s University School of Medicine. After medical school, I did my transitional year at the Family Medicine and Preventive Medicine department at Wayne State University in Michigan. My research interests include the role of radiation in palliative care, outcome disparities and gender equity in medicine. In my free time I enjoy puzzles, watching movies, visiting family/friends and spending time with my cat, Nebula.

We will be recruiting for 1 medical residency position through ERAS 2024, the position will start on 7/1/26.
