Welcome to the repository of my research publications. This collection encompasses a wide range of topics in software engineering, machine learning, and artificial intelligence, reflecting the evolution of research interests over the years.
The early work explores two foundational ideas in software engineering: the π-calculus as a formal basis for component composition languages, and the Meta-Object Facility (MOF) as a meta-meta-model for language-independent meta-model interchange via XMI.
Later work applies machine learning (Gaussian Mixture Models, Hidden Markov Models, Support Vector Machines) to handwriting recognition and writer identification, contributing to the fields of document analysis and pattern recognition.
Recent research focuses on the design and formal verification of LLM Agentic systems, proposing new paradigms for agent interoperability and tool protocol semantics.
This repository serves as a comprehensive archive of these contributions, spanning from foundational software composition theories to cutting-edge AI agent research.
