Speaker: Rudolph Pienaar, PhD, Staff Scientist at Boston Children’s Hospital
Event: BCH AI and Machine Learning Working Group Lecture
Talk title: Let’s Get Practical: Developing and Disseminating AI Research/Workflows to Audiences of Researchers and Clinicians Within BCH Using the ChRIS Platform

Dr. Pienaar discussed how we are often wowed by the potential of AI (and other sophisticated computational approaches) to transform research and clinical workflows. New approaches seem to magically hold unbounded promise. Yet there is often a large gulf between theory and practice, between a shiny new technique and having anyone just use it. The questions like “How do I get this? How do I get my data from PACS to connect to this? How do I go from DICOM to something that the neural network wants? How do I get results that are useful?” In this talk Dr. Pienaar provided some insights into practically developing, using, and disseminating “AI” (and other) workflows in the BCH clinical and research environment.

Talk Title: Machine Learning Reveals Widespread Demographic Structure in Laboratory Data

Blood laboratory measures such as glucose and hemoglobin are the basis for much of clinical decision making, yet baseline variation for many laboratory measures remains incompletely characterized across age, gender, and race groups. I will introduce foundational techniques from machine learning and statistical genetics and show how they can be applied to systematically unpack variation in blood laboratory data across population groups. These analyses reveal widespread demographic structure in blood laboratory data.
