Profile Summary

PhD in Physics with strong expertise in computational materials science, molecular dynamics simulations, and high-performance computing (HPC). I have extensive experience working with Fortran, Python, MPI, and GPU/CUDA to develop and optimise scientific simulation codes. My research at Research Centre For Green House Gases Innovation (RCGI) focuses on applying molecular simulations and machine learning techniques to materials science problems, including interfacial phenomena, transport properties, and predictive modelling. I am currently integrating local/open-source large language models (such as Qwen and Hermes) into research workflows to create intelligent tools for materials modelling and data analysis, with an emphasis on on-premise and privacy-preserving solutions. I have authored peer-reviewed publications and developed registered scientific software (INPI). In addition to academic research, I run Multiscale, a research and innovation company, where I work as a researcher and consultant on scientific computing and AI applications for materials. I am available for collaborative research projects, computational modelling, code modernisation (Fortran to modern Python/HPC), and the development of custom AI-assisted tools for scientific applications.
