Dr. Monica Tromp

Department of Archaeology

Main Focus

Monica is an archaeological scientist with bioarchaeological training and experience in a variety of microscope and chemical analyses. She is especially interested in how people have interacted with plants in the past. Plants provide breathable air, nutrition, textiles and medicine—without them we would not be able to exist. Understanding our shared history with plants is extremely important as our environment continues to change at an accelerated pace today.

The majority of Monica’s research career has consisted of examining microscopic plant and animal skeletons to figure out what people put in their mouths in the past. She uses this information to understand how people were interacting with their environments by comparing what she finds in their mouths to what was found in their environments. So far her research has helped to refine when the sweet potato was introduced into Polynesia, when bananas first entered Remote Oceania (specifically Vanuatu), and examined how drinking water was collected in Rapa Nui, an area with almost no accessible freshwater sources. Another highlight of her career was being involved in the discovery of lapis lazuli within the dental calculus of a medieval woman, which was listed as one of the top ten archaeological discoveries of 2019.


Curriculum Vitae

Monica received her B.A. (2010) and M.S. (2012) in Anthropology from Idaho State University and her PhD in Anatomy from the University of Otago (2017). She completed her doctoral thesis, “Lapita plants, people and pigs” in 2016, which was placed on the list of exceptional PhD theses in the Division of Health Sciences. Monica took a position as a postdoctoral researcher at MPI-SHH between 2016 – 2018. Monica is currently the Senior Laboratory Analyst with Southern Pacific Archaeological Research (SPAR), a research unit based in the Archaeology Programme at the University of Otago in New Zealand. Monica oversees several laboratory services for post-excavation analysis including zooarchaeological, microparticle, geochemical, lithic, aDNA and textile analyses. The majority of SPAR’s projects are in the wider Pacific region.
