Biography

Dr. Nissanka received his Ph.D. from Clarkson University, New York, USA in 2016, having studied turbulent dispersion and droplet dynamics in 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 the nature. Dr. Nissanka also worked as a visiting scholar at School of Architecture, Design and Built Environment, Nottingham Trent University, UK, before he joined the University of Moratuwa. Dr. Nissanka also has experience in working as visiting scientist at Naval Research Lab, Marine Meteorology Division, Monterey, California, USA. As a member of 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.

Research Activities : 

Dr. Nissanka is interested in computational techniques for turbulent dispersion including Lagrangian-Eulerian methods for studying pollutant transport in the atmospher and ocean. In particular, ocean oil spill modeling and particulate emmision in the atmosphere, which are critical for accurate prediction and evauation of environmental pollution and its' impacts. Dr. Nissanka is also interested in developing tools for simulating multi-phase flow systems that can be applied to wide variety of flow systems, including industrial fluid flow systems, geophysical flows. Further, Dr. Nissanka's research interests extends to study the climate change impacts, future projections of power requiremnts and sustainable future cities.
