About Me

Ignacio Vellido Expósito

I am a specialist in Artificial Intelligence and Data Science with experience in finance and academic research. My personal interests lie in the Reinforcement Learning, Ethics, Computer Vision, and Robotics areas of AI.

Career

Model Risk Data Scientist, Santander Group

Validating and challenging machine learning, statistical, and stochastic models across fraud, compliance, macroeconomic forecasting, and operational risk. Focused on model governance, performance, and regulatory compliance (EU AI Act, GDPR, ICAAP, IFRS9), while developing AI-driven tools, automated validation pipelines, and LLM-based systems for decision support.
