The Research Committee at the Health Effects Institute has selected alumnus Joseph Antonelli, PhD ’16, Assistant Professor in the Department of Statistics at the University of Florida, as one of three applicants from a field of highly qualified candidates to receive the Institute’s 2020 Antonelli received his award to explore “ Robust statistical approaches to understanding the causal effect of air pollution mixtures.” This project seeks to develop statistical methodology that allows for complex relationships between air pollution and health outcomes to be used to estimate causal effects of multivariate exposures. Additionally, the proposed methodology will allow for evaluation of separate subgroups in the population to identify the most vulnerable subgroups.
