Foster is currently an MS-PhD dual degree student at Penn Nursing. Having received a bachelors of science in nursing from Emory University, he worked as a cardiac intermediate care nurse at Grady Memorial Hospital. At Grady, he was quick to recognize the disparity in health care access  and the homelessness that plagued the patients he got to know on first name bases. The repeat readmission that he observed among his heart failure patients sparked his interest in pursuing a research doctorate in nursing. He is interested in the relationship between marginalization and poor cardiovascular health outcomes and the physiological response that results from marginalization to mediate that relationship. Specifically, his focus is on the effects of marginalization on the readmission of heart failure patients. Hence, he is interested in examining the relationship between social determinants of health and clinical events as well as identify the mechanism that mediates that relationship.

Originally, Foster is from Ghana, on the Western coast of Africa. He believes that growing up on the southern part of the sahara makes the concept of marginalization and social determinants of health a stack reality. Therefore, he is aware that the advancement of sub saharan Africa and the continent at large cannot be realized without the creation and application of translational scientific research. For this reason, he has a long term goal of transferring his research to Ghana and the entire African continent. Having lived in a Ghana, where health and social services are disproportionately distributed across the population based on age, gender and residential location, he is passionate about bridging the gap between healthcare and the underserved through research and education.
