I am deeply passionate about advancement of modern Bayesian latent variable methods, with a keen focus on developing tools that address pivotal public health challenges faced predominantly by low and middle-income countries (LMIC). My contributions include the development of general methods and the creation of publicly-accessible software tailored for world’s most updated pediatric pneumonia etiology estimates across seven sub-Saharan African and Southeast Asian countries. Additionally, in collaboration with demographers and statisticians, I’ve pioneered domain-adaptive mortality estimation for deaths occurring outside the civil registration and vital statistics systems using computer-coded verbal autopsy. Recently, I’ve been working to advance digital mental health for healthcare workers in Kenya, in collaboration with the Data Science Initiative in Africa. This effort draws upon my expertise in interventional and predictive mobile health, honed through pioneering studies in the US (Intern Health Study - world’s largest multi-year microrandomized trial, and Caregiver Quality of Life Study). I enjoy embracing and navigating the unique challenges presented within the LMIC contexts and seizing the opportunity therein to shape how statistics can effect meaningful change.
My research is motivated by biomedical and public health problems and is centered on the design and application of statistical methods that inform health decisions made by individuals, or precision medicine. Towards this goal, I focus on two lines of methodological research: a) structured Bayesian latent variable models for clustering and disease subtyping, and b) study design, causal and reinforcement learning methods for evaluating sequential interventions that tailor to individuals’ changing circumstances such as in interventional mobile health studies. I am committed to developing robust, scalable, and interpretable statistical methods to harness real-world, high-dimensional, dynamic data for individualized health. The methods and software developed so far have supported studies in diverse scientiﬁc ﬁelds including infectious disease epidemiology, autoimmune diseases, mental health, behavioral health, and cancer.

Congratulations to Dr. Tsung-Hung Yao and Dr. Irena Chen for successfully defending their theses! Dr. Yao’s thesis is entitled: “Bayesian Learning of Structured Covariances, with Applications to Cancer Data”; Dr. Chen’s thesis is entitled: “Joint Modeling Methods for Individual-level Variances as Predictors of Health Outcomes”. Good luck to your next stage of careers at MD Anderson Biostatistics and Max Planck!
Congratulations to Dr. Jieru Shi for successfully defending her thesis entitled “Statistical Methods for Assessing Time-varying Causal Effects: Novel Estimands and Inference” (Co-Chair with Walter Dempsey). Best wishes to your upcoming postdoctoral studies at University of Cambridge!
Thrilled to receive tenure! Heartfelt gratitude to family, students, collaborators, mentors, and reviewers for your help in reaching this milestone. Truly honored to be part of the esteemed umich community.
We are organizing the 2023 ICSA Applied Statistics Symposium, which will be held from Sunday, June 11 to Wednesday, June 14, 2023 in Ann Arbor, Michigan. I am co-charing the local organizing committee. Please consider attending!
