BACKGROUND

Dr. McGregor is interested in how software tools and data can be leveraged to improve manufacturing technologies and automate metrology used to qualify production parts. He investigates methods for leveraging manufacturing data (machine specifications, part design information, in-situ sensors, ex-situ images, etc.) and intelligent algorithms (statistics, machine learning, artificial intelligence) to predict the quality of manufactured parts. He is especially interested in developing models for qualifying part designs that have never previously been made and enabling first-time-right manufacturing strategies for additive.
