Aging - Epidemiology and Prevention of Falls in Older Age, Patient Reported Outcomes, Neighborhood Environment, Observational Cohort Studies, Design and Analysis of Randomized Controlled Trials, Analysis of Hospital Discharge and ED Visit Databases, and Electronic Health Records
Wenjun is interested in applications of statistical and data science tools to investigate medical and public health problems. His areas of expertise include:
- aging and injury preventions in older age;
- mental health, substance and disabilities;
- assessment of community influences on health, health behaviors and health care among older adults;
- production and dissemination of community-level health statistics using small area estimation models to assist public health agencies prioritize public health preventions; and
- applications of GIS and spatiotemporal analysis in public health research.
