Welcome!
I am an assistant professor in the Department of Statistics at the University of Wisconsin-Madison.
Before joining the Wisconsin-Madison, I was a Postdoctoral Fellow in the Data Science Institute at the Columbia University during 2021-2022. I obtained by Ph.D. from the Department of Statistics at the University of Michigan-Ann Arbor, where I was advised by Prof. Gongjun Xu and Prof. Xuming He. Prior to coming to Michigan, I received my B.S. in Statistics from the University of Science and Technology of China (USTC) in 2016.
My first name can be pronounced as "In-cho", and my name in Chinese is 何吟秋.
Research Interests
I am broadly interested in developing theory and methodology for analyzing large-scale and complex-structured data to address scientific problems arising from interdisciplinary studies. My current research interests include high-dimensional and large-scale statistical inference, mediation pathway analysis, network analysis, statistical machine learning, and also applications in statistical genetics and genomics and metabolomics.
