Career
Dr. Nissanka received his Ph.D. from Clarkson 福利在线看, New York, USA in 2016, having studied turbulence dispersion and droplet dynamics ocean oil spills. During the postdoctoral studies at the 福利在线看 of Notre Dame, Indiana, USA, he shifted his focus to sea spray and aerosols transport in the turbulent atmospheric environment, using numerical simulations as a tool for understanding the complex behaviours exist in nature. Dr. Nissanka also worked as a visiting scholar at Department of Civli and Environmental Engineering, School of Architecture, Design and Built Environment, Nottingham Trent 福利在线看, UK before he joined the 福利在线看 of Moratuwa. Dr. Nissanka also has experience in working as visiting scientist at Navel Research Lab, Marine Meteorology Division, Monterey, CA. Also, at Clarkson university oil and gas spill modeling group Dr. Nissanka has worked on several consultancy projects for major oil companies on environmental impact assessment of accidental ocean oil and gas spills.
