PNNL

Dr. Mark Engelmann delivers programmatic and technical leadership in support of U.S. and global interests in national security and energy missions related to the nuclear fuel cycle. He currently serves as program area manager for a portfolio of Pacific Northwest National Laboratory (PNNL) projects related to plutonium and uranium production detection, funded through the National Nuclear Security Administration (NNSA) Office of Defense Nuclear Nonproliferation Research and Development. Dr. Engelmann also supports PNNL’s projects and efforts to expand work supporting partnerships with NNSA’s Stockpile and Nonproliferation Stewardship programs.

He joined PNNL as a postdoctoral fellow nearly 20 years ago. Before moving into organizational and programmatic leadership roles, he spent more than a decade as a researcher at all levels, developing methods of chemical separation and analysis, with applications ranging from medicinal chemistry to nuclear treaty monitoring and nonproliferation. Dr. Engelmann was president of the Pacific Northwest Chapter of the Institute of Nuclear Materials Management from 2020 to 2022. He has a bachelor’s degree and doctorate in chemistry from the University of Idaho.
