Jessica Castner’s research agenda focuses on efforts to prevent, eliminate, and manage symptoms of dyspnea (“bad” breathlessness).  Her currently funded work is focused on diminishing the gender gap in adult asthma control, developing sensors and devices as clinical applications to improve asthma, and using a “big data” approach to ascertain asthma phenotypes (sub-types) and biomarkers. She employs multi-level modeling, time-series analysis, and meta-analysis to integrate health data from multiple, disparate sources.
