About Me

Ignacio Vellido Expósito

I'm a Data Scientist and Machine Learning Engineer with a passion for research in Reinforcement Learning, Computer Vision, Game Theory, and Robotics.

Career

Quantitative Model Risk Analyst, Santander Group

As a member of the Internal Validation Department, I am responsible for conducting validation, challenge and risk assessments of non-financial models, including Economic Research forecasts, Operational Risk, Compliance, and Anti-Money Laundering, with a focus in AI an ML. Additionally, I am advancing the department's software initiatives by contributing to the design of probabilistic models and financial algorithms, automating processes, and developing LLMs for decision-making.

Apr. 2023 - Present
Quantitative Model Risk Analyst

AI & ML Researcher, University of Granada

Started working at the beginning my bachelor's third year with the Intelligent Systems group, and full time afterwards. Most projects revolved around applications of AI and ML for transportation and video games, sometimes in collaboration with other industrial companies. I also contributed to the Unified Planning library under the AIPLAN4EU project, and won the Partial Order track in the 2020 International Planning Competition.
