Scientist: Dionisia Quiroga, D.O., Ph.D.

Dr. Dionisia Quiroga is currently a breast medical oncology fellow and NIH T32 post-doctoral research fellow at The Ohio State University Comprehensive Cancer Center (OSUCCC). She was recently hired to start as a breast medical oncologist and assistant professor in the Division of Medical Oncology at OSUCCC this August 2022.

Dionisia grew up in the mid-Michigan area and attended Michigan State University for her undergraduate, medical school, and graduate school education. She focused on general cancer vaccine development for her Ph.D dissertation research, but became specifically motivated to pursue breast cancer research after her cousin was diagnosed with metastatic breast cancer. Dionisia’s current research focuses on understanding how breast cancer can change and evade our natural immune response in order to develop new immunotherapeutic strategies for treating it. She also studies complications that may arise from breast cancer treatment (e.g. lymphedema) and how this may dysregulate the human immune response.

During her free time, she loves to spend time with her husband and son, go for long runs, and explore the culinary scene of Columbus, OH.
