Sancy Sebastian received her Master’s in Urban and Regional Planning with a specialisation in Infrastructure Planning  from CEPT University, Ahmedabad, India. Her research interests are in water, sanitation, sustainable wastewater management and geospatial data analysis. Sancy’s dissertation thesis was titled ‘Development induced tribal transformation: Case study of Muthuvan and Malayarayan tribe Idukki district’ and it received the best thesis award. She undertook a socio-economic survey of the tribal groups, and the study revealed the level of transformation of the two tribes over a period of three decades. This led to a clearer understanding and better recommendations for tribe-specific development programmes and schemes. She has also worked on a research study focusing on wastewater irrigation in Maharashtra on how wastewater is utilised in irrigation and associated health aspects.
