​PhD Mathematician | High-Performance CFD & Molecular Simulation | AI-Driven Data Analysis

Profile Summary

I am an Applied Mathematician specializing in the intersection of Physics-Informed Machine Learning (PINNs), Computational Fluid Dynamics (CFD), and Chemical Process Modeling. What sets my service apart is my expertise on high-performance clusters, allowing me to execute complex, high-fidelity simulations in a fraction of the time required by standard consultants. Core Expertise: Computational Mathematics: Solving complex PDEs and ODEs for chemical kinetics and fluid flow. Simulation & Modeling: CFD (aerodynamics, heat transfer) and Chemical process validation. AI/ML & Data Analysis: Building surrogate models to accelerate R&D and analyzing large-scale experimental datasets. End-to-End Solutions: From mathematical formulation to high-throughput computation and professional reporting. I provide rapid, research-grade results for startups and engineering firms needing deep technical insight and massive computational power without the overhead of enterprise cloud costs.
