Overview
My primary areas of research include methods for preserving data confidentiality, for handling missing values, for integrating information across multiple sources, and for the analysis of surveys and causal studies. I enjoy collaborating on data analyses with researchers who are not statisticians, particularly in the social sciences and public policy.

Outcome-Assisted Multiple Imputation of Missing Treatments
Journal Article Observational Studies · January 1, 2026 We provide guidance on multiple imputation of missing at random treatments in observational studies. Specifically, analysts should account for both covariates and outcomes, i.e., not just use propensity scores, when imputing the missing treatments. To do s ...

Journal Article Statistics and computing · October 2025 Probabilistic record linkage is often used to match records from two files, in particular when the variables common to both files comprise identifiers measured with occasional errors like names and demographic variables. We consider bipartite record linkag ... Full text CiteEfficient and Scalable Bipartite Matching with Fast Beta Linkage (fabl)
Journal Article Bayesian Analysis · September 1, 2025 Within the field of record linkage, Bayesian methods have the crucial advantage of quantifying uncertainty from imperfect linkages. However, current implementations of Bayesian Fellegi-Sunter models are computationally intensive, making them challenging to ... Full text CiteRecent Grants
