Biography

Dr. Matthew Asmussen is a post-doctoral research associate in the Geosciences group who joined PNNL in October, 2014 after receiving his doctorate in Electrochemistry and Corrosion Science at the University of Western Ontario in Canada. His research interests at PNNL involve the long term immobilization of radionuclides in various waste forms, the corrosion of glass waste forms and the development of getters for radionuclides. Prior to joining PNNL, a portion of his graduate work involved the study of the long term corrosion behaviour of stainless steel based metal alloy waste forms designed to immobilize 99Tc. He has experience in a wide range of analytical techniques such as SEM/XEDS/FIB, CLSM, XRD, TEM, XPS, ToF-SIMS, COD, Auger spectroscopy, optical microscopy, FTIR, Raman spectroscopy, ICP, UV-Vis and liquid scintillation; along with a wealth of experience with electrochemical techniques and analysis such as CV, LPR, EIS, CA/CP, SECM, MEC, galvanic coupling, and in-situ ATR-FTIR. His research experience is widely varied including corrosion, fuel cells, solar cells, nanomaterial synthesis, waste water treatment, lightweight alloys and nuclear waste management. In his spare time he enjoys playing hockey, spending time at the lake and cooking.
