Dr. Roos van Oosten began her academic career studying medieval history after which she began her archaeological degree that culminated in a thesis on urban archaeology. Her PhD dissertation at the University of Groningen focused on sanitation management, which she successfully defended in 2014. In 2011 she was appointed as university lecturer in urban archaeology at Leiden University. In addition to undergraduate and graduate teaching responsibilities, Roos is working on her VENI-funded project entitled 'Challenging the paradigm of filthy and unhealthy medieval towns'. Dr. Rachel Schats studied archaeology with a specialisation in osteoarchaeology at Leiden University and University College London after which she was appointed as a research and teaching assistant for the Laboratory of Human Osteoarchaeology in Leiden. Her PhD (defended November 2016) aimed at gaining a better understanding of the physical consequences of medieval developments, such as urbanisation and commercialisation, by comparing rural and urban skeletal populations. Concurrently, Rachel taught numerous undergraduate and graduate courses on human skeletal material at Leiden University, VU University Amsterdam, University of Groningen, and Saxion School for Applied Sciences. In January 2016 she was appointed lecturer in Human Osteoarchaeology at the Faculty of Archaeology, Leiden University. Dr. Kerry Fast holds a PhD from the Centre for the Study of Religion at the University of Toronto. Her doctoral research was a historical-anthropological study of Canadian women's religious lives. In more recent years, she has focused her research attention on traditional, distinct Mennonite groups, which has taken her to Bolivia, Mexico, and across Canada where she has conducted ethnographic research in Mennonite communities. She has published several articles on aspects of Mennonite religious life and is co-editor of Mothering Mennonite. Kerry is also a full-time language and copy editor, specialising in academic editing in the humanities and social sciences. She lives in Toronto, Canada. Nico Arts MA studied cultural and physical anthropology at Leiden University and pre- and proto-history at the University of Amsterdam. Since 1989, he has been employed as the urban archaeologist for the city of Eindhoven. Nico has published many studies concerning the Stone Age in the south of The Netherlands and medieval and early modern archaeology in Eindhoven. He has edited several volumes focusing on the urban archaeology of Eindhoven; most recently he was responsible for a major publication concerning the results of the excavation and analysis of the Catharina graveyard. Currently, Nico is writing up an archaeological synthesis of town and country in the Northern Kempen region between AD 1000 and 1650. Since 2009, Jeroen Bouwmeester MA has been employed by the Cultural Heritage Agency as a senior researcher of medieval and early-modern cities. He studied the archaeology of Northwest Europe at VU University in Amsterdam. After his graduation in 1997, he worked as a senior archaeologist at BAAC and as director of Synthegra. During this period, Jeroen directed large-scale excavations near Zutphen (Bronze Age-Middle Ages). His research at the Cultural Heritage Agency focuses on the development of expectation models of (sub)urban areas by combining historical, geographical, archaeological, and building historical data. He devotes special attention to the development of houses and other buildings in relation to urban planning, a topic which is being developed further in his PhD research.
