Sangeeta Mahajan
Ph.D. student

Sangeeta Mahajan was a practicing dentist and oral surgeon for 30 years. She received her Masters in Ancient Indian History and Culture from Tilak Maharashtra Vidyapeeth (Pune, India) in 2015 and an MPhil in Archaeology from Deccan College Post-Graduate Research Institute (Pune, India) in 2019. She is a dental anthropologist, interested in applying her knowledge of dental biology, anatomy, and histology to archaeological questions about diet, migration, and human health. Her Master's thesis in Archaeology was the first successful analysis of human dental enamel isotopes from the site of Inamgaon in India. She used these data to make inferences about paleodiet, paleoclimate, and age of weaning that have been completely inaccessible until she undertook this project. Sangeeta is a member of the Isomemo Initiative (funded by Max Planck Institute, Jena, Germany) and serves as the administrator of the Iso-India subdivision. She has published four  pathbreaking publications in International journals. In addition to her interests in bioarchaeology, Sangeeta completed a diploma in Urdu, a certificate in Prkrut, an advanced course in Persian, and is currently taking classes in Japanese and pursuing the third level (HSK3) in Mandarin Chinese. She has completed courses in Modi, Newari, Brahmi, and Old Persian Cuneiform. She is a high altitude trekker and has hiked in the Himalayas and the Sahyahdri Range. Her dissertation will focus on the influence of climate and environmental change on human migration and dietary choices during the Bronze Age. Sangeeta is beginning her Doctoral work in Fall, 2023.
