My research develops rigorous statistical theory, methodology, algorithms, and
software for drawing reliable conclusions from complex dynamical systems. I work with high-dimensional, longitudinal, multimodal, and unstructured data, including images, video, text, and sensor data. I have developed and applied novel statistical, machine-learning, and AI methods for estimation, testing, model selection, prediction, and decision-making across epidemiology, psychotherapy, agriculture, finance, engineering, and other domains.
