Before joining the University of Maryland in 2017, Professor Axel Krieger has been Assistant Research Professor and program lead for Smart Tools at the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, leading a group of scientists and engineers in the research and development of robotic tools and laparoscopic devices. Projects at Children's included the development of a surgical robot called smart tissue autonomous robot (STAR) and the use of 3D printing for surgical planning and patient specific implants. Professor Krieger holds several licensed patents for biomedical devices. He has several years of experience in private industry at Sentinelle Medical Inc and Hologic Inc. His role within these organizations was Product Leader developing devices and software systems from concept to FDA approval and market introduction. Axel completed his undergraduate and master’s degrees at the University of Karlsruhe in Germany and his doctorate at Johns Hopkins, where he pioneered an MRI guided prostate biopsy robot used in over 50 patient procedures at three hospitals.
