Jichun Xie received her BS degree in Statistics from Peking University in 2006, and her PhD degree in Biostatistics from the University of Pennsylvania in 2011. Her PhD advisers were Dr. T. Tony Cai and Dr. Hongzhe Li.

In 2011, she joined Temple University Fox School of Business as an Assistant Professor of Statistics. During the next three years, she focused on developing high-dimensional inference methods for complicated biomedical data such as genetics/genomics and neuron imaging data.

In 2014, she joined Duke University as Assistant Professor of Biostatistics and Bioinformatics, and were promoted to  Associate Professor in 2018.  Through her work at Duke, she has grown new interests in cancer and immunology. Her current research focuses on developing novel computational and statistical methods for genetics and genomics data in the area of cancer immunology, including  DNA-seq, RNA-seq, single-cell RNA-seq, flow-cytometry,  and microbiome metagenomic data. Methodologically, she focuses on large-scale multiple testing, multi-scale methods, and machine learning.
