Arda received his B.Eng. in Environmental Engineering from Istanbul University, Turkey in 2009. The title of the final thesis was ''Treatment of Pharmaceutical Waste Water by Membrane Bioreactor (MBR) Processes''. He completed his M.Sc. studies at the Technical University of Munich (TUM) in 2013 with merits, his thesis was entitled ''Adaptation Measures to Climate Change in the Eastern Mediterranean with a Focus on Water Resources'' supervised by Prof. Peter Wilderer. In his professional career, Arda has experience as a consultant, researcher and project engineer; including GFA Consulting Group (Hamburg, Germany), Rachel Carson Center (Munich, Germany) and Istanbul Water and Sewage Administration (Istanbul, Turkey). Between October 2013 and November 2016, Arda conducted his Ph.D. research at the Pollution Prevention and Resource Recovery (PPRR) chair group of Environmental Engineering Water Technology department, led by Prof. Piet Lens, at UNESCO-IHE (Delft, the Netherlands). Currently, he is employed at the electronics manufacturing industry as an environmental management expert.
