Staff Scientist (Machine Learning Single-Molecule Center)

St. Jude Children's Research Hospital Cincinnati, OH

About the Job

St. Jude Children’s Research Hospital has a unified mission to use cutting-edge research to discover the origins and treatment of childhood disease, especially cancer, and to improve the lives of patients. Towards that end, at the Single-Molecule Imaging Center (SMC) in the Department of Structural Biology, we provide a critical platform to perform state-of-the-art single-molecule fluorescence imaging on biological systems relevant to medical research. We are looking for a highly motivated data scientist, that will leverage their expertise in advanced statistical concepts and modern machine learning to develop novel analysis methods that improve quantity and quality of information extracted from experimental data. The applicant will skillfully translate ideas into user-friendly implementations that can be used daily by non-experts. The successful applicant will be an integral part of the Single-Molecule Imaging Center and the larger, expanding community of data scientists and computational biologists across St Jude.
