Bio

Dr. Renjith S. Bhadran is a public health academic, behavioural systems researcher, theory developer, programme leader, and international mentor with more than twenty years of professional experience spanning healthcare administration, public health practice, research management, academic leadership, international collaborations, postgraduate education, and healthcare systems development.

He is the developer of Bhadran’s Point-of-Generation Segregation Theory (PGST), published in Scientific Reports (Nature Portfolio Q1 Journal), one of the world’s leading multidisciplinary scientific journals. His doctoral research generated a comprehensive scientific ecosystem consisting of original theories, behavioural frameworks, measurement systems, benchmarking indices, quality assessment tools, and implementation models designed to improve healthcare waste segregation, environmental sustainability, occupational safety, and healthcare quality.
His academic work integrates public health, behavioural science, environmental health, healthcare sustainability, implementation science, and healthcare systems research. Through his teaching, mentorship, international engagement, and translational research initiatives, he is contributing to the development of Behavioural Precision Science as an emerging area of scholarship within healthcare waste management and public health systems.

Original Scientific Contributions
  1. Introduced a behavioural precision framework for biomedical waste segregation, conceptualizing segregation as a measurable behavioural process rather than solely a regulatory compliance activity.
  2. Developed an Indian-origin theoretical framework for behavioural precision in biomedical waste management.
  3. Proposed a public health theory for biomedical waste segregation that was developed in Kerala and published in a Nature Portfolio journal.
  4. Developed a point-of-generation behavioural measurement architecture comprising:
    • Precision Behaviour Score (PBS)
    • Precision Change Score (PCS)
    • Point-of-Generation Segregation Accuracy (PGSA)
  5. Applied the concept of behavioural drift to biomedical waste segregation, providing a theoretical explanation for deterioration in segregation precision over time.
  6. Developed the Point-of-Generation Segregation Index (PGS Index) for behavioural assessment of segregation practices.
  7. Developed the Global Segregation Safety Scale (GSSS) as a framework for evaluating segregation safety performance.
