Dr. Qi Long is the founding Director of the Center for Cancer Data Science (CCDS) and serves as Associate Director for Cancer Informatics at the Penn Institute for Biomedical Informatics. He also directs the Biostatistics and Bioinformatics Core at the Abramson Cancer Center, where he leads initiatives to integrate data science into cancer research and patient care. Dr. Long is recognized as an elected fellow of the American Association for the Advancement of Science and the American Statistical Association, as well as a member of the International Statistical Institute.

Dr. Long’s research bridges innovative statistical and machine learning methods with impactful biomedical applications to advance precision medicine and population health. Supported by NIH, PCORI, and NSF, his work spans analysis of complex health data—from -omics and EHR to mobile health—addressing challenges like missing data, causal inference, and fairness in algorithms. He has led large research networks and clinical studies, and currently co-directs (with Dr. Nicola Mason of Penn Vet) the PRECINCT initiative, part of NCI’s Cancer Moonshot.
