As an Epidemiologist at the Marshfield Clinic Research Institute, Jennifer is currently the project manager for the US Influenza Network’s Vaccine Effectiveness (Flu VE) study. The study annually recruits over 1,000 children and adults seeking treatment for an acute respiratory illness. Through RT-PCR testing of nose and throat swabs for influenza, the study generates timely estimates of how well the influenza vaccine is performing at preventing medically-attended, laboratory-confirmed influenza illness. In addition, she also oversees study activities for a cohort study examining immune response to influenza vaccination in children and adolescents. As a Project Manager, Jennifer develops protocols for data collection and abstraction, maintains regulatory documents, contributes to the development of new study ideas, communicates and responds to key study issues across contributing sites, produces study reports and manuscripts, maintains data quality and performs data analyses.
Jennifer received her Master of Public Health (MPH) from Emory University in 2009. Her thesis investigated health disparities by maternal race, maternal age and plurality among infants born late preterm (32-36 weeks gestation). As a student she gained experience as an intern at both state and national public health agencies. At the Nebraska Department of Health and Human Services she cleaned and analyzed data associated with Hepatitis C test results to determine the annual number of incident cases of Hepatitis C in the state. With the National Center on Birth Defects and Developmental Disabilities at the Centers for Disease Control and Prevention she assisted with review of studies and data entry of surveys regarding illness surveillance in schools following Hurricane Katrina.
Prior to joining the Marshfield Clinic in January 2013, Jennifer was a project lead at Northwestern University, Feinberg School of Medicine where she directed a large, multi-site, cross-sectional grant investigating the prevalence of misunderstanding of over-the-counter pain relievers and potential interventions to reduce medication errors. She was the lead author of a manuscript regarding the feasibility of interventions to prevent unintentional misuse of analgesic medications and a manuscript highlighting variability found in labeling of prescription medications containing acetaminophen which may impact consumer understanding of proper use.
