Tim G Lach
R&D Associate Scientist
Tim joined Oak Ridge National Laboratory as an associate research scientist in the Advanced Nuclear Materials group in the Materials Science and Technology Division in February 2020 before switching to the Radiation Effects and Microstructural Analysis group in May 2021 and to the newly formed Nuclear Energy Materials Microanalysis group in 2022. Previously, he was a research scientist in the Reactor Materials and Mechanical Design group in the Nuclear Sciences Division at Pacific Northwest National Laboratory. His research interests focus on the characterization and testing of advanced materials for nuclear fission and fusion energy applications. In particular, he uses analytical electron microscopy and atom probe tomography in conjunction with properties testing to elucidate processing-microstructure-property-performance relationships in materials exposed to extreme environments. He is an extensive user of the Low Activation Materials Development and Analysis laboratory (LAMDA) and the Center for Nanophase Materials Sciences (CNMS).
