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 if) 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 what the proper way is to state a conclusion in pattern-matching disciplines (e.g. fingerprint or firearm identification) and what information a forensic examiner should have when analyzing data. I am currently working on developing an algorithm for toolmark identification.

I am the mother of twins, and I am married to Justin Humphreys, who works on ancient philosophy and mathematics and has more recent applications of ethics in fairness and machine learning.
