Asif Rahman

Senior Scientist
Machine Learning in Healthcare

My interests are at the interface of digital health, time series analysis, and machine learning. I currently work on applications of machine learning in healthcare at Philips Research with a special interest in decision analysis for clarifying uncertain and dynamic decision problems in critical care. Previously, I obtained my PhD in neural engineering and was a data scientist at Stitch Fix.
