Katie A. Hemer joined the Institute of Archaeology in January 2022 after a number of years as a Lecturer and Senior Lecturer at the University of Sheffield. Katie specialises in the study of human skeletal remains excavated from early medieval (5th-11th century AD) cemetery sites in Britain. She combines osteological analysis with skeletal histology and biomolecular techniques (e.g. stable isotope analysis) to explore past population health, dietary reconstruction, migration, and childhood in the past. She has excavated a number of sites in the UK, and currently co-directs the St Patrick's Chapel Excavation Project in collaboration with Dyfed Archaeological Trust. She is a strong advocate and speaker of the Welsh language, and has presented her work through the Welsh language channel, S4C, on a number of occasions. A central element of Katie's research is the archaeology of childhood; she co-authored a book, Medieval Childhood: Archaeological Approaches, and is President of the Society for the Study of Childhood in the Past (SSCIP).
