Research Bio

Dr. Cooper is an emerging leader in the domestic and international manufacturing research communities. His research interests are in the areas of physics-informed machine learning (PIML) and explainable artificial intelligence for digital twin enablement via improving the observability of manufacturing processes and product quality. His research has led to the development of a novel PIML framework and the invention of several novel machine learning methods and unobtrusive sensing techniques for pre-, in-, and post-process prediction of part quality in various manufacturing fields, including machining, directed energy deposition, human-robot collaborative assembly, and casting.
