Renjith Seela Bhadran, developer of Bhadran’s Point of Generation Segregation Theory (PGST), is an Indian academic and public health researcher whose work integrates behavioral science with public health to address systemic challenges in healthcare waste management. He is an Assistant Professor in the Department of Public Health at Amrita School of Medicine, Amrita Vishwa Vidyapeetham, Kochi, India, where he primarily teaches Social and Behavioral Science to healthcare students.
Bhadran holds a Master of Science in Public Health (MSc PH) from the University of Bedfordshire and an MBA from the University of Nottingham, United Kingdom. His academic work reflects a multidisciplinary perspective that combines public health systems analysis, behavioral science, and environmental sustainability. His research initially focused on onsite biomedical waste segregation challenges in healthcare facilities and later expanded to investigate the cognitive and behavioral determinants influencing segregation practices at the point of generation.
During his doctoral research at Amrita School of Medicine, Bhadran developed Point of Generation Segregation Theory (PGST), a behavioral–systems framework conceptualizing biomedical waste segregation as a precision-dependent behavioral process occurring at the moment of waste generation. The theory introduces analytical constructs such as the Precision Behavior Score (PBS) and Moment-Based Precision Behavioral Fidelity (MBPBF) to evaluate segregation accuracy at the point of disposal, along with behavioral drift analysis for monitoring system performance and improvement over time.
PGST also proposes the Global Segregation Safety Scale (GSSS), a structured benchmarking framework designed to classify institutional segregation performance and support international comparisons in biomedical waste management practices. By reframing waste segregation as a behavioral decision-making process rather than solely an operational activity, the framework provides a new interdisciplinary perspective linking healthcare worker behavior, environmental sustainability, and public health safety.
Bhadran’s research sits at the intersection of behavioral systems research, public health impact assessment, health education, and environmental health management. His work is increasingly gaining international academic attention for its potential to strengthen training systems, institutional audits, and evidence-based policy development in biomedical waste management.
