Curriculum Vitae

Abelardo Carlos Martinez Lorenzo

Lead AI Scientist · AI for Good (Development Economics)

AI researcher and applied machine learning scientist working at the intersection of natural language processing and development economics. Builds systems that help researchers and policymakers retrieve, structure, and synthesize evidence from scientific literature. I currently work on AI systems that make development research more accessible through evidence synthesis, structured extraction, and domain-specialized language models.
