I build simulations and learning experiments, then test what their comparisons actually establish: strong baselines, held-out evaluation and explicit controls.
My direction is the evaluation and fidelity of language-model systems: whether a model, an agent or a policy behaves the way its results say it does. The projects below are where I practise that method, on reinforcement learning, recurrent networks and human-behaviour data.
| Project | What I did |
|---|---|
| SCRES reinforcement learning · simulation |
With Alexander Garrido: supply-chain simulation and Gymnasium/PPO experiments judged against matched comparators. Start with the same-contract comparison. |
| Motor-RNN connectivity computational neuroscience |
Neuromatch team project, then my independent equal-plasticity control, which separates structural density from trainable connections. Start with the control note. |
| Spectral analysis of cognitive labor human coordination |
My reanalysis of Andrade-Lotero and Goldstone's human-search experiment, with a past-only temporal audit. Predictive advantage is not established. Start with the temporal audit. |
- HeliOS: a collaborative educational RISC-V kernel in C, to which I contributed; architecture notes and QEMU smoke tests.
- ContratIA Abierta: open-procurement data pipelines, APIs and traceable signals for human review, not automated allegations.
- ChaosLab: double-pendulum dynamics with numerical checks and an interactive explanation.
Read the question and the stated limitations, inspect a saved result and its method, then follow the documented test path. The existing evidence can be inspected without refitting any model.
Private work is described in the CV and is not published: a retrieval prototype for LLM support routing, numerical-analysis coursework, and a model audit of marmot social networks with Adriana Maldonado-Chaparro.
