Research Interests

Naomi Marks has a background in mass spectrometry, isotope geochemistry, and ore deposit geology. Her research focusses on thermal ionization mass spectrometry (TIMS), electron microscopy (EPMA), nuclear forensics and attribution, geochemistry of uranium ore concentrates and early fuel cycle materials, national nuclear forensics libraries and databases, geochronology and geochemistry of planetary samples, formation and evolution of meteorites and planets, mineralogy and petrology of meteorites, isotopic and chemical evolution of the early solar system materials, and hydrothermal alteration and water-rock interaction in active and fossil hydrothermal systems and their relation to ore forming processes.

Marks’s recent work has been in developing National Nuclear Forensic Library capabilities and algorithms for provenance assessment for front-end fuel cycle materials, with a particular expertise in uranium ore concentrate. She has extensive experience in international engagements in nuclear forensics and has provided training and engagement for countries including Argentina, Austria, Australia, Azerbaijan, Canada, Georgia, Germany, Hungary, Israel, Moldova, Morocco, the Republic of Korea, Singapore, Sweden, Ukraine, and the United Kingdom, as well as numerous International Atomic Energy Agency (IAEA) sponsored trainings, events, and consultancies. Marks is a member of the International Technical Working Group Nuclear Forensics Laboratories Steering Committee.
