Theoretical Physicist | Scientific Modeling & Simulation | AI & Quantitative Analysis Expert

プロフィール概要

I am an Assistant Professor of Theoretical Physics with a strong background in mathematical modeling, complex systems, and computational analysis. I specialize in translating advanced physical theories into practical, implementable models for research and industry applications. My expertise includes: * Physics-based modeling and simulation (deterministic and stochastic systems) * Numerical methods and scientific computing (Python) * Statistical physics and complex systems * AI model evaluation and reasoning validation (LLMs) * Semiconductor and graphene-based systems (emerging technologies) I have contributed to peer-reviewed research and worked as a STEM expert in AI training, focusing on evaluating and improving model reasoning in mathematics and physics. I am particularly interested in collaborating with startups, R&D teams, and organizations that require rigorous scientific thinking, high-level modeling, or technical validation of complex ideas. I bring a combination of theoretical depth, computational skill, and practical problem-solving. I am open to long-term collaborations and advisory roles for deep-tech and R&D projects.
