Research Interests

My primary research interests lie in developing effective statistical and machine learning methods for high-dimensional ``objects'' with low-dimensional underlying structures. Examples of these objects include images, surfaces, networks, and time-indexed paths on non-linear manifolds, coming from neuroscience, computer vision, epidemiology, genomics, and meteorology.

My recent study focuses on developing novel machine learning methods to extract knowledge from large neuroimaging datasets.  With the advancement of in vivo brain imaging techniques, large-scale neuroimaging datasets containing more than 1k or even 10k subjects (e.g., the Adolescent Brain Cognitive Development Study dataset, the Human Connectome Project dataset,  the Alzheimer’s Disease Neuroimaging Initiative dataset, and the UK Biobank dataset) can be easily accessed now. With large samples, we gain more statistical power, narrower margin of errors and more reproducible results, but we also face modeling and computational challenges. I am dedicated to discovering efficient, elegant and practical solutions to these challenges.
