Electrical Engineering student Ms. Jana Gonzalez completed a summer research fellowship at Lawrence Berkeley National Laboratory (LBNL)

Recent electrical engineering graduate Jana Gonzalez was awarded a 10-week, paid, research fellowship at LBNL during the summer of 2024. She worked in the Applied Numerical Algorithms Group (ANAG), which develops advanced numerical algorithms and high-performance computing (HPC) software for solving partial differential equations, with a primary focus of high-resolution and adaptive finite difference methods for simulating porous media flows. Jana developed a predictive adaptive mesh refinement approach in the Chombo-Crunch reactive transport framework that infers regions for refinement using Gaussian Process regression (GPR) models. She developed code that predicts the location of refinement boxes using GPR and evaluated the performance of several stationary and non-stationary kernels. Jana tested her approach by simulating single component species advection test cases that model cross-sectional flow within cm-scale fractures at different axial flow velocities.
