Overview
Interests include Bayesian methods, complex data structures (correlated data, multivariate data recorded over time, data on different measurement scales), dimension reduction methods, and applications in health and medicine.
Recently I was honored to present work in progress on discovery of sepsis subtypes in sub-Saharan Africa as the University of Cambridge's 20th Armitage Lecturer.
Other projects include investigation of health effects of exposures to mixtures of environmental contaminants (particularly in relation to child health and neurodevelopment), theory and methods addressing robustness of clustering methods, and development of methods in reproductive and environmental epidemiology.
Duke today provided a nice overview of some of my work.

Recent Scholarly Works
Progeny effects of rotenone exposure depend on parental toxicity.
Journal article Toxicol Sci · March 2, 2026 Parental exposure to toxicants can affect progeny health. However, laboratory studies often employ exposures that result in loading of pollutants to gametes or toxic effects to parents, which could indirectly affect germ cell or gamete health. Here, we too ... Full text Link to item CiteBayesian Modeling of Nearly Mutually Orthogonal Processes
Journal article Bayesian Analysis · January 1, 2026 Functional factor analysis is an important dimension reduction method for functional and longitudinal data. Factor loadings give insight into patterns of variability of the observations, while latent factors provide a low-dimensional representation of the ...

Journal article Ann Appl Stat · September 2025 Sepsis is a life-threatening condition caused by a dysregulated host response to infection. Recently, researchers have hypothesized that sepsis consists of a heterogeneous spectrum of distinct subtypes, motivating several studies to identify clusters of se ...
