Biography

Qunhua Li is an Associate Professor of Statistics at Penn State.

She received her Ph.D. in Statistics from University of Washington in 2008. 

Her primary research interests concern developing statistical methods for uncovering complicated patterns in large and complex biological data. Her work is at the interface between statistics and biology. She has been developing latent variable models and machine learning techniques to identify and infer scientifically meaningful structures from high-throughput genomic and proteomic data.

Li joined Penn State as an Assistant Professor in 2011. She is also a primary faculty member of the Bioinformatics and Genomics program.
