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.
