Ms Iresha Atthanayake?s research interests lie in the general area of fluid mechanics and heat transfer. She is a senior lecturer in the Department of Mechanical Engineering. She graduated from University of Peradeniya- Sri Lanka in 2003 and she has completed her MPhil at University of Moratuwa in 2013. Ms Atthanayake has 9 years of teaching experience and currently she teaches DMX3401 ? Fluid Mechanics and Thermodynamics for higher diploma level and DMX5836 – management for Engineers, DMX6204 ? Computational Fluid Mechanics for undergraduate students. Ms Atthanayake is also contributing to the facilitation of the Worldwide M Sc in Sustainable Energy Engineering Program (SEE World MSc), conducted by the Royal Institute of Technology and the University of Galve, Sweden, for which OUSL is the facilitating University in Sri Lanka. Her work in this program includes supervision of student group projects and thesis projects.
