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.

BAYESIAN LEARNING OF CLINICALLY MEANINGFUL SEPSIS PHENOTYPES IN NORTHERN TANZANIA.
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 ...
