Jennifer Cabezas
Jennifer Cabezas is a PhD student at the Mayo Clinic where her thesis project bridges bench science with community-engaged implementation science to address racial disparities within Triple-Negative Breast Cancer (TNBC). Specifically, her work aims to define the distinct underlying biological mechanisms of TNBC in non-Hispanic Black (NHB) women and further understand the perceptions and experiences of NHB women navigating health care before and after receiving their risk notification for breast cancer. Through her research, Jennifer has developed a diverse set of laboratory skills and sharpened her critical thinking. This scientific foundation, coupled with her community engagement work, has illuminated the critical gap that exists between scientific discoveries and their real-world implementation. Jennifer is committed to narrowing this gap by continuing to uplift historically marginalized communities through her research and advocating for improved policies that promote equitable access and care. She holds a BS in Microbiology from Clemson University where she was awarded the Almeda Jacks Outstanding Undergraduate Award in 2020.
