Research Topics

For most anticancer drugs, we do not have precise rules for response prediction and mechanistic understanding of therapy resistance. Moreover, new drugs with distinct mechanisms of action get approved every year. But it takes many years to accumulate clinical data, which creates a significant gap between our current ability and the goal of cancer precision medicine. Our vision is that the data integration approach, leveraging the ever-growing volume of data from public domains, is a cost-effective solution to fill in the gap. Many statistical and machine learning methods can achieve knowledge transfer from previous data to the study of a new problem. Therefore, the general theme of our research is to develop infrastructures that transfer knowledge from big data to inform the cancer therapy decision.

The specific focus of our current work is how to utilize both genomics and imaging data to identify new regulators in cancer immune evasion. In the first direction, we study how to predict immune evasion regulators by leveraging the vast amount of functional genomics datasets and the spatial transcriptomics data produced by recent technological progress. In the second direction, we develop machine learning infrastructures for feature selection in imaging data to understand how spatial interaction among different cells can determine the anticancer immune response. Our deliverables are infrastructures that enable the users to leverage the vast amount of data resources in public domains to find immune evasion mechanisms in their own clinical studies.

Dr. Peng Jiang started his research program at the National Cancer Institute (NCI) in July 2019. His Lab focuses on developing big-data and artificial intelligence frameworks to identify biomarkers and new therapeutic approaches for cancer immunotherapies in solid tumors. Before joining NCI, he finished his postdoctoral training at the Dana Farber Cancer Institute and Harvard University. During his postdoctoral research, Peng developed computational frameworks that repurposed public domain data to identify biomarkers and regulators of cancer immunotherapy resistance. Notably, his computational model TIDE revealed that cancer cells could utilize the self-protection strategy of cytotoxic lymphocytes to resist lymphocyte killing under immune checkpoint blockade. Dr. Peng finished his Ph.D. at the Department of Computer Science & Lewis Sigler Genomics Institute at Princeton University, and his undergraduate study with the highest national honors at the Department of Computer Science at Tsinghua University (GPA rank 1st in his year). He is a recipient of the NCI K99 Pathway to Independence Award, the Scholar-In-Training Award of the American Association of Cancer Research, and the Technology Innovation Award of the Cancer Research Institute.
