Enrique Crespo Fernández

AI Researcher specializing in the intersection of Deep Learning and Formal Reasoning. Currently a PhD candidate developing neuro-symbolic methods that leverage program synthesis to enable online learning and logical inference. I hold a strong mathematical foundation in Mathematics and Theoretical Physics, which informs my work on interpretability and generalization beyond statistical correlation through program synthesis. Proficient in logic programming, I am dedicated to moving beyond "black box" models by integrating structured knowledge representations into autonomous agents. Outside my main research area, I have experience in deep learning, particularly in sequence modeling and physics-informed neural networks. I am seeking a research role that demands rigorous theoretical understanding and the ability to innovate at the fundamental architectural level.

Experience

University of Bristol
Teaching Assistant
2024-2025
Bristol, UK
  • Data Science Project Unit - Supervised and mentored postgraduate Data Science students on industry-sponsored group projects, guiding research design, experimentation, and reporting. Acted as the primary liaison between student teams and corporate partners, ensuring timely delivery of project milestones and clear communication of technical findings.
  • Machine Learning Unit - Assisted in delivering lectures and practical sessions on machine learning topics to undergraduate Computer Science students. Provided one-on-one support during lab sessions, helping students understand complex concepts and debug code.
  • Artificial Intelligence Unit - Supported the teaching of symbolic AI fundamentals as well as multi-agent systems to third-year Computer Science undergraduates.
Lukkap
Data Scientist Intern
2021-2022
Madrid, Spain
  • Built an end-to-end machine-learning pipeline to process and analyse open-ended survey responses, integrating clustering, tree-based models, and NLP sentiment analysis; cut analysis time from days to minutes.
  • Developed a psicometric model and analysis pipeline from the ground up to extract personality traits from employee survey data, enabling HR teams to better understand workforce dynamics. Opening a new revenue stream for the company.
  • Presented insights to stakeholders and delivered training sessions enabling non-technical colleagues to use the analysis tools independently.
