Career
Dr. Nissanka received his Ph.D. from Clarkson University, New York, USA in 2016, having studied turbulence dispersion and droplet dynamics ocean oil spills. During the postdoctoral studies at the University 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 University, UK before he joined the 成人头条. 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.
