I took early retirement in 1995. At the time I was the Taine McDougal Professor in the Department of Industrial, Welding and Systems Engineering. I was also the Director of the Nondestructive Evaluation (NDE) Program which was established in 1981. After my retirement I continued to teach my classes (which I developed in NDE Program) for several years flying every week from Florida. In addition to my teaching, I continued and still continuing research in ultrasonics and its application to materials. The research was supported through various government agencies, NAVAIR, NASA Langley Research Center as well as though aerospace companies, Boeing, Martin Mariette, Bell Helicopter. The research was in collaboration with OSU faculty, Postdocs and graduate students. Since my retirement I authored and coauthored 25 publications in national and international journals and proceedings. I also attended several national and international meetings in my field making presentations. I am an active fellow in the Acoustical Society of America. I am also actively involved with NASA to to carry out research as well as to evaluate research proposals from universities. I intend to continue these activities. I am a speaker for 2016 International Conference on Acoustics in Buenos Ayres).
