Senior Lecturer (Grade II)

Department of Civil Engineering Faculty of Engineering Technology

Dr. Ganila N. Paranavithana has obtained his primary education from Kadugannawana Primary School and his secondary and tertiary education from St/Sylvester’s College Kandy. After the G.C.E Advanced Level examination, he entered the Faculty of Engineering of the University of Peradeniya, which led him to obtain his degree in Bachelors of Sciences in Civil Engineering. After completing his degree, he has worked in several local and international institutions before getting his post-graduate qualifications. Dr. Paranavithana obtained his Master degree in Environmental Pollution Control Engineering from the Faculty of Engineering, University of Peradeniya in 2012, which led him to apply for a Ph.D. As soon as he completed his MSc, he won the Japanese government Scholarship to read for his Ph.D. at Saitama University, Japan. He has specialized in Geoenvironmental Engineering, which is a highly developing field in the world. Dr. Paranavithana is currently working as a Senior Lecturer attached to the Department of Civil Engineering of the Open University of Sri Lanka.
