Shu Jiang

Shu Jiang, also known as Joy Jiang, is a Canadian biostatistician and associate professor in the Division of Public Health Sciences at the Washington University School of Medicine in St. Louis.[1] She is also the co-founder of Prognosia Inc with Graham Colditz, a technology company that develops AI models that assess digital mammograms to accurately predict the risk of breast cancer.[2] Prognosia's first tool, Prognosia Breast, earned Breakthrough Device Designation from the U.S. Food and Drug Administration (FDA) in June 2025,[3] and the company was acquired by Lunit in September 2025.[4][5]

Jiang is known for her methodological contributions to breast cancer risk prediction using high-dimensional mammogram images.[6] In April 2023, The New York Times and CNN interviewed Jiang for a feature about breast density and cancer risk, in which she discussed recent findings on how changes in density over time may indicate elevated breast cancer risk.[7][8] In December 2024, U.S. News & World Report cited Jiang in an article about artificial intelligence and breast cancer screening. Discussing her team's work on longitudinal mammogram analysis, Jiang said: "Our new method is able to detect subtle changes over time in repeated mammogram images that are not visible to the eye."[9] More recently, media coverage has also included BreastCancer.org, which described a newer AI-based approach in which Jiang used multiple years of mammograms to enhance risk prediction.[10]

She is an associate editor for the journal Biometrics[11] and a statistical reviewer for JAMA Network Open.[12] Among other awards and honors, Jiang has been named a Forbes 30 Under 30 in Healthcare in 2023[13][14] and received the MERIT award from the National Cancer Institute (2021-2027).[15]

Education

Jiang received a B.Sc. in statistics from Simon Fraser University (2012-2015), an M.Sc. in statistics from Western University (2015-2016), and a Ph.D. in statistics from University of Waterloo (2016-2018), where her supervisor was Richard Cook.[16][17] From 2018-2019, she trained as a postdoctoral fellow in biostatistics at the Harvard T.H. Chan School of Public Health, where her supervisor was Rebecca Betensky.[1]
