Christian Lezcano

I am based in San Lorenzo, Paraguay. My work evolves from a background in Discrete Optimization and Bioinformatics toward current interests in Geometric Deep Learning, Agentic AI, and RAG systems.

I teach Algorithms II and ICT (Information and Communication Technologies) at the Columbia University of Paraguay.
