Hire Dr. Ferenc Agoston B.

Hungary

Ph.D. Mathematician | Simulation, Dynamical Systems & Disease Modeling | Ex-Rice Univ.

Profile Summary

I am a Ph.D. Mathematician and Computational Scientist specializing in dynamical systems, modeling, and algorithmic simulation. With prior research experience at Rice University (USA), I bridge the gap between advanced theoretical mathematics and practical, code-based solutions for complex business problems. I specialize in scenarios where standard statistical tools fail and first-principles modeling (ODE/PDE/Agent-Based) is required to understand system behavior. Core Expertise: Dynamical Systems: Modeling complex, non-linear time-dependent systems (ODEs/PDEs/DDEs) to predict future states and bottlenecks. Epidemiology & Biology: Developing viral dynamics and population models to forecast spread and risk. Simulation Engines: Building custom stochastic simulations (Monte Carlo, Gillespie algorithms) to quantify uncertainty. Scientific Computing: Translating mathematical formulas into high-performance, production-ready code. Technical Stack: Languages: C++, Python, Java, Julia, MATLAB, Mathematica. Tools: Differential equation solvers, Agent-based modeling frameworks, Statistical analysis. Background: Currently based in Hungary, I work as an independent consultant for international clients. My experience at Rice University has given me a deep understanding of US research standards and communication expectations. I am available for freelance projects, from short-term mathematical problem solving to long-term simulation development. Deliverables I typically provide: Custom mathematical models formulated from your business questions. Python/C++ simulation scripts and source code. Technical reports explaining model limitations and predictive insights.
