I am an Assistant Professor of Biostatistics at the University of Minnesota, and an Affiliate Faculty in the Analytics Core of the Masonic Institute for the Developing Brain.
I obtained my PhD in Biostatistics from Johns Hopkins University in 2023, advised by Ciprian Crainiceanu. Before that, I obtained my Bachelor's in Statistics from Zhejiang University in 2018.
