Speaker Bio

Dr. Mary O’Brien recently converted to staff scientist following her G.T. Seaborg Post-doctoral Fellowship on the Materials Compatibility Team in Sigma Manufacturing Sciences Division at LANL. Her research focus is understanding hydrogen embrittlement phenomena in a wide variety of metallic systems, with a current focus on actinide materials.  Mary earned a B.S. in Materials Science and Engineering from Washington State University, and M.S. and Ph.D. in Metallurgical and Materials Engineering from Colorado School of Mines. Her graduate research involved designing low carbon pipeline steels that are more resistant to hydrogen induced cracking in severe oil and gas applications. Prior to attending graduate school, she worked as a civilian nuclear engineer at Puget Sound Naval Shipyard refueling Ohio class submarines.
