Prof Manjula Ranagalage is a Professor in the Department of Environmental Management, Faculty of Social Science and Humanities of Rajarata University of Sri Lanka, Mihintale, Sri Lanka. He joined the Department of Social Sciences in 2008 as a permanent lecturer. Before joining the department, he was an Assistant Lecturer in the Department of Geography, University of Colombo. Currently, He is working as a Head of the Department of Environmental Management.

Prof. Ranagalage obtained his Bachelor of Arts degree with a Geography specialization and a First Class at the University of Colombo in 2006. Furthermore, he earned two master’s degrees in Geo-informatics and Geography at the Postgraduate Institute of Agriculture, the University of Peradeniya in 2010, and the University of Sri Jayewardenepura in 2013, respectively. He completed a PhD in Geo-Environmental Sciences at the Graduate School of Life and Environmental Sciences of the University of Tsukuba, Japan, in 2019.

Prof. Ranagalage has published more than 60 journal articles in SCI, SSCI, ESCI journals, and other peer-reviewed journals, more than 50 conference publications, and many books. His research disciplines include GIS & Remote Sensing, Geoscience, Geospatial Analysis, Urban Geography, Land change science, Urban Studies, Urban Sustainability, Urban Heat Island, Spatial Analysis, urban green volume and build-up volume, and disaster management. It is also noteworthy that the geographical area he has chosen for conducting research covers Sri Lanka and Japan, India, China, Indonesia, Iran, Nigeria, and some countries in the African continent and the Middle East of the Asian continent.

To advocate for further scholarship and disseminate research-based new knowledge, he has provided more than 30 Master of Science (MSc) students with academic advice and guidance for completing their theses. His recent most scholarly engagement involves working as a reviewer for more than 50 international peer-reviewed indexed journals.
