Xiyu Peng

I am an Assistant Professor in the Department of Statistics at Texas A&M University. Before that, I was a postdoctoral fellow in the Department of Epidemiology and Biostatistics at Memorial Sloan Kettering Cancer Center, working with Drs. Ronglai Shen, Katherine Panageas, and Margaret Callahan. Prior to joining MSK,  I obtained my Ph.D. degree in bioinformatics and statistics from Iowa State University, working with Dr. Karin Dorman.

My research interests lie at the interface of statistics and biomedical sciences (genomics, proteomics, and immuno-oncology). My methodological research is mainly inspired by collaborative research where challenges arise in real data analysis and novel computational and statistical methods are heavily demanded. I am passionate about addressing scientific questions and advancing health care by developing cutting-edge statistical and computational methods for modern complex biomedical data. My research philosophy is to develop statistically powerful and computationally efficient methods to tackle complex analytical challenges in biomedical research.

Research Interests:

Methodology: Computational and Statistical Genomics, Model-based Clustering, Latent Variable Model

Application: Cancer Immunotherapy, Multiplexed Imaging, Flow Cytometry, Spatial Transcriptomics, Microbiome, Next-generation Sequencing

Current Research Projects:

1. Resolving temporal and spatial dynamics in single-cell omics data with application in immuno-oncology:

• Longitudinal single-cell data 

• Imaging-based spatial transcriptomics/proteomics data

2. Efficient and scalable computational methods for large-scale omics data.
