I am an Assistant Professor at the University of Pennsylvania in the Criminology Department. My training is primarily in statistics and data science, and my work is driven by interdisciplinary projects in public policy, public health, and forensic science.
I am interested in the intersection of statistics and the law, particularly how (and whether) we can answer legal questions by using statistics. I have written about nonparametric estimation in causal inference, as it relates to the legal question of whether we can attribute an outcome (e.g. cancer) to an exposure (e.g. exposure to a harmful chemical). I have also written about the statistical foundations of forensic science. I have written about the proper way to state a conclusion in pattern-matching disciplines (e.g. fingerprints, firearms, toolmarks identification) and what information a forensic examiner should not have access to when analyzing evidence. I am currently working on developing an algorithm for toolmark identification.
I am currently serving as the Chair of the American Statistical Association’s Advisory Committee on Forensic Science.
I am the mother of twins, and I am married to Justin Humphreys, who works on ancient philosophy and mathematics, as well as applications of ethics in fairness and machine learning.
