Fan Li, PhD, is an associate professor in the Department of Biostatistics at the Yale School of Public Health, a faculty member in the Yale Center for Methods in Implementation and Prevention Science (CMIPS), the Yale Center for Analytical Sciences (YCAS), as well as an affiliated faculty member of the Yale Alzheimer’s Disease Research Center (ADRC). He received his PhD in Biostatistics from Duke University in 2019 and joined the Yale Biostatistics faculty the same year. His primary research interests are in developing causal inference methods for both observational studies and pragmatic clinical trials, including those employing cluster randomization and stepped wedge designs. His methodological contributions span causal mediation analysis, principal stratification, treatment effect heterogeneity, selection bias, and techniques for improving both internal and external validity in treatment comparisons across diverse study designs. Dr. Li has been the principal investigator of multiple NIH- and PCORI-funded awards. He has published over 170 peer-reviewed articles in statistical methodology and collaborative research, advancing the design and analysis of clinical and population health studies.

Hillary Lum, MD, PhD, is a geriatrician and palliative care physician who is passionate about designing, testing, and implementing pragmatic interventions for older adults with serious illness, including mild cognitive impairment and dementia, and family care partners. She is professor of medicine in the Division of Geriatric Medicine at the University of Colorado School of Medicine. She did her MD/PhD at University of Wisconsin-Madison and internal medicine residency at University of Pittsburgh Medical Center. As a 2016 NIA Beeson Scholar, Dr. Lum designed and demonstrated the efficacy of a novel advance care planning group visit intervention for older adults in primary care, and studied adaptation for individuals with mild cognitive impairment and their care partners. In 2021, she was one of the inaugural NIA IMPACT Collaboratory Health Care System Scholars. Her research focuses on community engagement, pragmatic interventions through the patient portal, and implementation science. She is part of the IMPACT Collaboratory Patient and Caregiver-relevant Outcomes Core.
