Worked as Research Assistant in the field of Geotechnical and Geoenvironmental Engineering.The research area encompasses wide ranging effects on hydraulic, chemical, and relevant geotechnical properties of subsurface barrier and containment system.

Term: Fall, 2018/University of Massachusetts DartmouthCourse: CEN 305; Soil Mechanics (Recitation) Solved and clarified different mathematical and conceptual problems on core soil mechanics topics such as Grain Size Analysis, Soil Classification, Permeability, Atterberg Limits, Flow Net, Shear Stress, Effective stress, Mohr Circle, Unconfined Compression, Consolidation, and other relevant topics.

Worked as a Graduate Research Assistant with concentration on f Water Resource and Environmental Engineering, especially on Groundwater Hydrology. My work encompasses understanding transport mechanisms of colloidal particles in subsurface environment by employing mathematical modeling framework coded in MATLAB. The overarching goal of my research is to analyze how the mathematical models can predict the transport and retention of copper nanoparticles in saturated porous media under presences of natural organic matter.
