Heinrich Winkelmann Fellowship

Since 2014, the Deutsches Bergbau-Museum Bochum has offered two research fellowships per year in the areas of mining history and mining archaeology. The three-month research visits to the DBM offer PhD holders in history and archaeology an excellent opportunity to carry out their own project in mining history, mining archaeology or material science, at a respected research museum belonging to the Leibniz Association. The Heinrich Winkelmann Fellowship comprises three months’ funding, a total of 6000€. Applications from outside Germany are encouraged. Current calls for applications are published on this page.

Our fellows

Mai Lin Tjoa-Bonatz, art historian and archaeologist (Ph.D. 2001, Technische Universität Darmstadt), is teaching on Southeast Asia’s culture and history at several German universities. She has joined excavations in Syria and Indonesia. She was formerly a Visiting Research Fellow in Singapore. In 2018, she was appointed as visiting professor at the National University of the Philippines. Curating exhibitions her interest also addresses missionary history and maritime cultural heritage of Southeast Asia. At the Technische Universität Darmstadt she joined research projects on “Housing of Historic City Centers” and “The Global History of Technology, 1850-2000” focusing on goldworking and -mining in colonial-period Indonesia. As curator she has published on art historical and archaeometric aspects of ancient Javanese gold jewelry.

History of Goldmining and Goldworking in Southeast Asia, 1850-1945

As part of  the research project GLOBAL-Hot at the Technical University Darmstadt the study aims to analyze the global history of technology by investigating artefacts and technological systems of gold mining and goldworking in insular Southeast Asia of the late colonial period. The focus lies on island Indonesia, which was described as the fabulous ancient „goldland“. In the first millennium CE Indian goldsmiths came. Later, in the seventeenth century saxon miners worked on the island of Sumatra. In the nineteenth century Chinese, American or European mining workers, companies, geologists or entrepreneurs engaged in the quest for the islands‘ precious metals.

With this research I want to highlight rather dynamic instances on transcultural transfer, circulation and encounter. The study is promising in evaluating primary written sources, ethnographic writing together with so far unpublished museum artefacts and other visual material. Not only the instances of transcultural transfer of technologies, resources or tools used by acteurs from different ethnic groups or origin but also the cross-breading and co-existence of local and transcultural notions as well as recycling or tinkering resulting in hybrid technological systems or artefacts  contradict to the assumption of a continuous history of development and the one-sided perspective of a Western-influenced modernisation paradigm. The thematically wide-ranging academic environment of the Deutsches Bergbau-Museum Bochum offers valuable reading on the research subject and provides transformative experiences.

From June – August 2019, Tracy carried out research dedicated to the development of low-molecular weight cyclohexanone-based polymeric varnishes for paintings conservation with improved chemical properties. Under the leadership of Dr. Elena Gómez-Sánchez, Tracy’s research capitalized on her background in synthetic organic chemistry to establish a route towards tailor-making an analog of MS2A, a popular varnish currently used by paintings conservators, with chemical modifications to make the final varnish more resistant to yellowing.

Prior to arriving in Bochum, Tracy obtained a B.S. in Chemistry from the University of California at Berkeley (2006 – 2010) and a Ph.D. in Organic Synthesis at Princeton University in the MacMillan Group (2012 – 2017). Given her life-long appreciation for easel paintings, Tracy elected to apply her knowledge and skills in chemistry to the conservation of easel paintings and continued basic research towards the development of improved materials tailor made for paintings conservation. After completing her Ph.D., Tracy began training in Paintings Conservation in the Winterthur/University of Delaware Program in Art Conservation, where she is currently entering her final year of study.

Immediately following her departure from the Deutsches Bergbau-Museum Bochum, Tracy will begin a one year internship in Paintings Conservation at the Rijksmuseum in Amsterdam as part of her final year curriculum towards obtaining her Masters in Art Conservation (degree expected August 2020).

Nicolas Gailhard (Ph.D. 2007, Université de Paris I -Panthéon-Sorbonne, Paris) was a member of the “Mines” ANR project directed by Catherine Marro (CNRS) and Thomas Stöllner (Ruhr-Universität Bochum). He has worked in Europe, Syria, Turkey, and the Caucasus for more than 15 years. His main area of research is archaeometallurgy and experimental archaeology in the Mediterranean and the Near East from the Chalcolithic to the Bronze Age. In 2010, he conducted a research programme on Iron metallurgy in Turkey at the Koç University's Research Center for Anatolian Civilizations. He is now Research Associate in the team “From Village to State in Ancient Near-East”, Department National Center for Scientific Research (CNRS), Nanterre, France and Director of Arkeoservice.

Regine Müller, Dr. des. – graduated in 2003 with Magister Artium in Early and Prehistorical Archaeology at the Justus Liebig University of Gießen, with the archaeological analysis of an early medieval graveyard. PhD thesis in Archaeology and History of the Roman Provinces at the University of Frankfurt about the archaeological-archaeometrical analysis of lead finds from the Roman republican site of Sanisera, Menorca, finished in 2014. The thesis was based upon a preliminary material study within the context of the international, European Union sponsored project „Rome’s Conquest of Europe: Military aggression, native response and the European public today“, during 2005/2006.

Subsequent research in provenance studies of lead sling bullets, momentarily focused upon material from Germany and Scotland, in cooperation with Prof. S. Klein (Deutsches Bergbau Museum, Bochum); J. H. Reid (Trimontium Trust, Scotland) and Dr. A. Posluschny (Research Centre Keltenwelt am Glauberg).

Since 2005 volunteer work within the non-profit organization “Archäologie im Gleiberger Land e.V.”; head archaeologist there since 2009, researching and undertaking rescue excavations at the late La Tène period oppidum of the Dünsberg (Biebertal) and its surrounding burial sites.

Extensive experience in field archaeology (excavation and surveying) within research programs, rescue excavations and field schools in Germany, Spain (Menorca) and Portugal, ranging from neolithic to modern times. Sites excavated include settlement sites, military forts, medieval castles, graveyards and urban archaeology.

Since 2015 employed at Sascha Piffko – Archäologische Untersuchungen (SPAU) as archaeologist, working as field director and technician, responsibilities including on-site documentation (digital and analogue), preparing reports, research and lectures (Justus-Liebig-Universität Gießen).
