01About

Hi, I'm Diego.

I am a data science student at ESCOM – Instituto Politécnico Nacional, now on an academic exchange in Bogotá, Colombia. An internship at Infosys Limited, where I worked on trust analytics for AI agents, left me with a question standard tools do not answer: how should a system infer, step by step, whether an agent can still be trusted? Sequential inference is also how brains and animals decide under uncertainty, so I am moving towards computational neuroscience. My first research note asks whether hidden engagement states explain what tiny recurrent networks predict.

  1. 01AI Engineering Intern · Infosys · 2026

    Trust analytics for AI agents

    When software agents act on their own, how do you tell from their behaviour whether they can still be trusted?

    • Built the trust-analytics layer of a team-built Agent Governance Framework: feature engineering, supervised and unsupervised adversarial detection, and PSI drift monitoring, with Streamlit and Dash dashboards
    • Built 'Attack Day', an adversarial simulation with synthetic attacker agents that stress-tests the framework's trust scoring
    • Python
    • Anomaly detection
    • Drift monitoring
    • Dashboards

03ResearchWhat I'm exploring

Why can someone know what to do, want to do it, and still not start?

Notes from computational neuroscience, published while they are still plans.

  1. Fig. 1The line is the model's belief, trial by trial, that the simulated participant is engaged. The grey 90% band shows where that belief falls in 90% of 200 re-runs of the same session. The bars underneath mark the stretches where the participant was truly disengaged.

    Strategy or state?

    Research note

    A planned test of whether engaged and disengaged states, rather than new learning rules, explain why very small recurrent networks predict choices better than standard reinforcement-learning models.

Where it started

That question pulled me from AI systems towards computational models of engagement and choice.
