The goal of my research is to develop statistical methods to help understand diseases of aging at the cellular/molecular level. I am interested in using high-throughput genomic data to develop mathematical models of the key biological processes and molecular mechanisms that underlie age-related decline in general, and cancer in particular. In addition to advancing our scientific understanding, this will enable the development of accurate prognostic and diagnostic tools for precision medicine.

My methodological research focuses on:

- robustness to model misspecification,
- nonparametric Bayesian models,
- frequentist analysis of Bayesian methods, and
- efficient algorithms for inference in complex models.

- models for de-biasing high-throughput sequencing data,
- inferring cancer tumor phylogenetic trees (clonal evolution),
- biostatistical analysis of X-linked Dystonia Parkinsonism (XDP), and
- models for tuberculosis risk assessment.
