In 2000, Waldthausen worked as research fellow at the Centre de Recherché sur le Conservation des Collections (CRCC) where she performed research on the autochrome process. Her work was published in the ICOM-CC Triennial Meeting Preprints 2003. Von Waldthausen has since published and lectured on various topics international and nationally, in the field of photograph conservation and preservation.


    In 2001, Waldthausen established the Fotorestauratie Atelier VOF, conservation lab for photograph conservation and digitization of fragile materials of which she is Director. In this setting she has worked as consultant and conservator for all major Dutch Institutions and abroad. In 2011 she was asked to assist in writing a research proposal for, "Photographs and Preservation. How to Save Photographic Works of Art for the Future?",  which received funding from the Netherlands Organisation for Scientific Research (NWO), Science4 Arts. Von Waldthausen is currently external expert for this project. Prior to this von Waldthausen was advisor in the European SEPIA project and in the COST Action G8.


    Von Waldthausen taught the Specialist Certificate Program in Photograph Conservation at the University of Melbourne School of Conservation from 2006 until 2011 and has been guest lecturer in photograph conservation at the University of Amsterdam and other Universities since 2007. She has taught an extensive amount of workshops throughout Europe. Von Waldthausen was the Working Group Coordinator of the Photograph Materials Working Group of ICOM-CC from 2005 - 2011 and President of the Dutch Association of Conservators from 2010 until 2013.
