RESEARCH EXPERIENCE

Texas Tech University Lubbock, TX

Present Position 1: Graduate Research Assistant, Soft Matter and Complex Fluids Group, Texas Tech University 2016-present

Identified a key hydrodynamic contribution responsible for the self-assembly of emulsion suspensions in shear driven flow by:

oFormulating a physical model for multi-particle interactions.

oDeveloping a CFD code to implement the model and perform simulations in a periodic system by means of numerical schemes (e.g., Euler, RK4, RK adaptive, Ewald Sums).

Generated relevant statistical data (Particle Density Functions, Pair Correlation Functions) in MATLAB for dense and sparse systems to highlight key differences by utilizing the High-Performance Computing Centre (Linux, BASH scripting).
