About me
I am an assistant professor of biostatistics at the Institute for Informatics, Data Science, & Biostatistics at Washington University School of Medicine in St. Louis. My research integrates causal modeling and machine learning for more reliable real-world evidence generation and building responsible AI algorithms in health care. I am the principal investigator of the CausAI Lab. I received my PhD in Biomedical Informatics from Columbia University, MS in Computational Biology from Harvard University, and BA from Boston University.
Hiring! I am looking for one postdoctoral fellow or senior data analyst. Please email me your CV, cover letter, and 2-3 publications if you are interested in working in my lab. Please see my lab website for more information.
Prospective PhD Students I am looking for 1-2 PhD students starting Fall 2024. Please apply directly to the Biomedical Informatics and Data Science (BIDS) PhD program at Washington University School of Medicine. In your PhD application, please explicitly mention your interest in working with Professor Linying Zhang. Existing BIDS and Computational & Systems Biology (CSB) PhD students interested in rotating through the lab should email me directly.
You can reach me at linyingz [at] wustl [dot] edu or on Twitter.
