PNNL

Matthew Olszta has been working at PNNL for nearly 15 years, performing high-end electron microscopy characterization on a wide variety of materials, including structural materials to secure a safer future for our nuclear fleet, to helping elucidate the complex nanostructures of carbon rods utilized in next generation cooling systems. He has constantly pushed to develop interweaving networking groups both for early career staff members, as well as the electron microscopy community at large. Olszta’s vision is to improve ways to teach and mentor staff through development of virtual reality for scientific instrumentation. His development of nanocartography protocols for the transmission electron microscope have drastically improved data collection and analysis, and is currently being developed into a stand-alone software platform that all electron microscopists can use for performing more meticulous microscopy.

Olszta is involved in a variety of projects at PNNL. He believes all research groups should have access to high-end electron microscopy capabilities. While his major thrust areas include analysis of corrosion in nuclear grade stainless steels, as well as alloys for consolidated processing techniques, his varied experience throughout his career, from bio-materials to solid oxide fuel cells (SOFCs) to vitrification of low activity waste (LAW) glasses, gives him a unique outlook and approach to collaboration. By approaching analysis through a first principles basis, he is able to quickly assess the necessary research goals for a specific project and also provide insight into what more can be achieved, thereby possibly elucidating a greater breadth to expand current research. One of his main goals is to educate non-microscopists about the limitations of the technique, as well as help guide their research so they can obtain the information they need.
