National and International Recognition
Fellowship from NRF Singapore for Post-doctoral study: 2012 to 2015.

Scholarship from MHRD India for Master’s study: 2002-2004.
Executive Summary
Dr. Behera has post-doctoral experience of more than 4 years, and his research focuses on the broad area of “Air Quality and Atmospheric Chemistry”. He has been immensely involved in practical research problems on societal issues in mega cities, including methodology for policy making process to reduce pollution levels, and assessment of human health risks due to existing pollution scenarios. His post-doctoral research problem at NUS Singapore was related to occurrence, characterization, source apportionment and assessment of human health risk of urban particulate matter during haze episodes in megacities like Singapore and Shanghai. His Ph.D. research problem at IIT Kanpur was based on two aspects of atmospheric chemistry as follows: (1) control environmental chamber study to examine the kinetics and equilibrium of secondary inorganic aerosol formation at laboratory scale, and (2) investigation into formation of atmospheric organic and ammonia-based inorganic secondary aerosols in fine mode in ambient air based on field measurement experiments.

His current research and teaching interest are based on cutting-edge interdisciplinary research related to air pollution and its control, specifically on monitoring and modelling of air pollutants, source apportionment of urban aerosols, policy evaluation for reduction of air pollutants, application of GIS in air quality management, and human health risk assessment due to environmental pollution.
