- About PSI
Dr. Welzenbach is a geologist, whose specialty is in sedimentary petrology. Her current focus is the characterization, curation, and analysis of planetary materials, namely meteorites and spacecraft returned samples (asteroid and lunar). Her research interests include examining chondrite regolith breccias and applying her findings to the theories regarding their formation and origins.
Dr. Welzenbach has spent the last 15 years as the Smithsonian Institution’s National Museum of Natural History’s Collections Manager. Curation activities included the management (inventory, database, and imaging), storage, and conservation of meteorites. She has been key in providing meteorite samples to the scientific community and for public outreach. As part of the U.S. Antarctic Meteorite program, she has classified and characterized over 10,000 meteorites from Antarctica, participated in two ANSMET expeditions to the trans-Antarctica mountains to collect meteorites, and managed the development and installation of the Smithsonian’s new Antarctic Meteorite cleanroom storage facility. She currently serves on the Nomenclature Committee of the Meteoritical Society.
