Simulation & Modeling Expert

Ph.D. candidate in Chemical Engineering (Texas A&M University) building CFD and kinetic Monte Carlo models that turn transport theory into reproducible, high-impact code.


Who am I here?

  • Computational fluid engineer with a bias for validated simulations and clean data
  • C++/Python modeler crafting adaptive kMC and multiscale solvers for crystallization, fermentation and catalysis
  • HPC-ready workflows (MPI, OpenMP, CUDA) to shorten iteration cycles without losing accuracy
  • Fluent with ANSYS, OpenFOAM, COMSOL, LIGGGHTS for coupled physics

How I Work?

  • Lean, testable models; benchmark early against experiments or literature baselines.
  • Performance-aware code (profiling and parallelism) without sacrificing readability.
  • Communicate results with clear visuals and concise engineering narratives.

 Some Tools I Have Used and Learned

vscode vscode python pytorch MATLAB bash jupyter ansys gcc spyder blender git

  • CFD / Multiphysics: ANSYS Fluent, OpenFOAM, COMSOL, Basilisk, LIGGGHTS
  • Numerics & HPC: MPI, OpenMP, CUDA; coarse time-stepping and multiscale coupling
  • Data & Viz: NumPy, Pandas, Matplotlib, Seaborn, Gnuplot, SciPy
  • CAD & Prep: SolidWorks, AutoCAD, Blender for geometry/meshing workflows

Code-Driven Projects

  • Adaptive kMC for Crystal Morphology (C++) — Physics-informed, thermodynamics-aware kMC across growth regimes; captured dual roles of crystal modifiers for better morphology prediction.
  • Multiscale DRM Catalyst Deactivation (C++/Python + HPC) — Coupled kMC, mesoscopic, and macroscopic solvers; coarse time-stepping cut runtime from 17 days to 6 hours while preserving coke formation fidelity.
  • CFD–PBM Bubble Column Solver (OpenFOAM) — Coupled CFD with population balance modeling to reach ~99% accuracy on bubble size distribution; evaluated breakage/coalescence kernels.
  • CFD–DEM Tablet Coater (OpenFOAM + LIGGGHTS) — Simulated heat and mixing in rotating drums; quantified drum speed and air temperature effects to guide pharmaceutical coating settings.
  • Slug Flow in Annular Micro-Pipes (ANSYS Fluent) — Modeled multiphase slug flow to study contact angle and velocity impacts on regime stability for micro-reactor designs.
  • Direct Air Capture Module for Aviation (COMSOL) — Designed and simulated a DAC prototype integrated with aircraft flow; optimized skin friction and module placement under flight conditions.
  • Photo-Catalytic Micro-Reactor (COMSOL) — Modeled continuous-flow micro-reactors to boost photo-catalytic degradation yields via ALD-informed surface design.
