Expertise

My main focus was about wastewater load allocation (WLA) approaches and I worked as a project assistant that is supported by TUBITAK (The Scientific and Technological Research Council of Türkiye). I was interested in both stochastic and deterministic optimization methods like DE, PSO, LM, HS, GA, CG coding with Matlab. After 2019, I continued my PhD degree and I focused on calibration and validation of mHM (mesoscale hydrological model) for Susurluk Basin.
