    Marilyn J. Hammer, PhD, DC, RN, FAAN

    Dr. Hammer has dedicated her program of research to understanding associations between glycemic status, metabolism, and immune function in patients with cancer, including how these mechanisms impact risks for poor symptom experiences and outcomes. In alignment with precision health targets, the goals based on findings from these investigations are to develop a symptom risk assessment tool and design individually tailored interventions for improved symptom management and outcomes. In addition, Dr. Hammer has published a body of work related to precision health and associated ethical, legal, and social implications. She has presented her work nationally and globally, including countries in North and South America, Europe, and China.
