Our mission


Our mission in the HITI lab is to apply machine learning to big problems in healthcare, including developing diagnostic and predictive imaging models, validation of existing models, and a focus on the fairness and explainability of AI.

Our projects encompass a wide range of topics from computer vision to natural language processing to radiology workflow. We strive to base each project on a real clinical need and end with the implementation of our products into a clinical workflow.
