NU is all about fresh perspectives. So is our website.
Dr Swakangkha Ghosh
- Assistant Professor
- Geographic Information Systems
Dr. Swakangkha Ghosh earned her PhD degree in active tectonics and paleoseismology from the Indian Institute of Technology (ISM), Dhanbad. However, majority of the work related to her Ph.D. was completed from Wadia Institute of Himalayan Geology, Dehradun where she was working as a research scholar in an ISRO funded project. She has competed her master’s in Applied Geology from Dibrugarh University, Assam and her bachelors in Geology (Hons.) from North Eastern Hill University, Meghalaya.
Prior to joining NU, Dr. Ghosh worked as a Research Scientist at the North-Eastern Region node for Disaster Risk Reduction (NER-DRR) of the North-Eastern Space Applications Centre (NESAC), Department of Space, Meghalaya. Her research mainly focussed on applying remote sensing and GIS techniques for the comprehensive analysis and management of various natural hazards in north-eastern states of India. At NESAC, she was also actively engaged in various outreach and capacity building activities.
Her current research focuses on assessing earthquake hazards, especially in the Himalayan region. She believes in taking up an interdisciplinary approach using remote sensing, geophysical techniques, and geochronology to assess the paleoseismic scenario of any region.
Dr. Ghosh has to her credit several peer-reviewed research publications in various national and international journals.
