Biography:

Dr. Dimitrios Pylorof is an aerospace engineering postdoctoral research associate in Idaho National Laboratory’s Systems Science and Engineering Department. His work involves using intelligent techniques in estimating the state of critical energy infrastructure and assisting in making informed decisions related to safe and efficient operations. Before coming to INL he was a postdoctoral fellow at Georgetown University, working on theory and algorithms for distributed computation, fault-tolerant optimization and machine leaning as part of the U.S. Army Research Laboratory’s Internet of Battlefield Things Collaborative Research Alliance (IoBT-CRA). He earned his doctorate and master’s in aerospace engineering from University of Texas at Austin. He holds a bachelor’s in mechanical engineering from the National Technical University of Athens, Greece.​
