Biographical Sketch:
Dr. Palmer received his B.S. and M.S. degrees in Metals Science and Engineering and Ph.D. in Materials Science and Engineering (1999) from the Pennsylvania State University, where he studied under Professor Tarasankar DebRoy. He also holds a Master of Business Administration degree (2007) from the Pennsylvania State University.
From 2000 through 2007, he was at Lawrence Livermore National Laboratory (LLNL), Livermore, CA, where he was first a post-doctoral technical associate and advanced to the position of metallurgist with the Materials Science and Technology Division in the Chemistry, Materials, and Life Sciences Directorate. He is currently a Research Associate in the Laser Processing Division at the Applied Research Laboratory Penn State.
Dr. Palmer is also active in a number of professional capacities. He is currently chair of the C7B sub-committee on Electron Beam Welding and Cutting and is also a member of the Peer Review Panel for the Welding Journal Research Supplement, the Editorial Board of the journal, Science and Technology of Welding and Joining, and a Key Reader for Metallurgical and Materials Transactions.
He has also received numerous awards from several technical societies, including the A.F. Davis Silver Medal Award in 2007, the Koichi Masubuchi Award in 2006 and the William Sparagen Memorial Award in 2005 from the American Welding Society, the Geoffrey Belton Award of The Iron and Steel Society in 2000, and the winner of the ASM International Graduate Student Paper Competition in 1999. He is the author or co-author of over 40 articles and reports.
