Biography:

Dr. Thomas Lillo is a materials staff scientist at Idaho National Laboratory whose principal interests and expertise include microstructural and mechanical property characterization (SEM, TEM, precession electron diffraction, OIM, x-ray diffraction, tensile testing, high temperature creep testing, etc.) of metals, metal alloys and ceramics. Current research programs in include the characterization of high temperature creep behavior and microstructural development in high temperature nickel-base alloys for the intermediate heat exchanger associated with the Very High Temperature Reactor (VHTR) program and computational modeling & simulation of creep in welds in a g’ strengthened, nickel-base alloy for fossil energy applications. He also performs advanced microstructural characterization using state-of-the-art TEM techniques on fission product migration in the SiC layer of irradiated TRISO fuel particles from the Advance Gas Reactor experiment. He received his doctorate, master’s and bachelor’s in metallurgical engineering from Michigan Technological University. He has over 45 peer-reviewed publications and 8 patents. His awards include co-author INL Outstanding Scientific Paper of the Year (“Identification of Silver and Palladium in Irradiated TRISO Coated Particles”, J. Nuc. Matls, 2014) and co-author in Outstanding Engineering Paper of the Year (“Threshold Stress Creep Behavior of Alloy 617 at Intermediate Temperature”, Mat. Sci. Engg. A, 2014) as well as Outstanding Mentor of the Year by the DOE-Office of Science, Undergraduate Research Programs in 2002.
