He has joined CEGIS on 21 April, 2021. He has working experience on hydrodynamic modeling in software like HEC-RAS. He has conducted his undergraduate thesis titled “Flow and Salinity modeling of Kobadak-Sibsa River System by HEC-RAS”. Primary focuses of this study were to investigate the effect of sea level rise on salinity of the study area and scenario development to examine the impact of any future change in salinity condition. He has worked in a project in his undergraduate titled “Analysis on River Bank Erosion-Accretion and Bar Dynamics of Naf River”, where he analyzed bar dynamics of Naf River and calculated its bank erosion-accretion using multi-temporal satellite images.
