AMP Lab Director
Christian A. Widener received his Ph.D. in Mechanical Engineering from Wichita State University in 2005, with a specialization in materials science. Prior to earning his doctorate, he worked for six years on the installation and repair of gas turbine generators. After earning his doctorate, Dr. Widener became a research scientist at the National Institute for Aviation Research (NIAR) working on friction stir welding of aluminum alloys for the aerospace industry. Since 2010, he has been an Associate Professor in both the Materials and Metallurgical Engineering and Mechanical Engineering departments at SDSM&T.
Dr. Widener is the Director of the Arbegast Materials and Processing (AMP) Laboratory, a cutting-edge research facility using advanced metals processing, joining, and cladding technologies, including friction stir welding, laser powder deposition, ultrasonic welding, and cold spray. Dr. Widener also directs the Repair, Refurbish, and Return to Service (R3S), a South Dakota 2010 Research Center and the Advanced Manufacturing Process Technology Center. These research centers focus on using advanced material processing for additive manufacturing and repair for many industrial and defense related applications.
Dr. Widener has more than 50 publications and international conference proceedings on friction stir welding and cold spray technologies.
