Research

My research focuses on understanding the mechanisms through which organisms and machines learn to construct representations of the world. With a background in physics, I employ methodologies and frameworks from neuroscience, mathematics, and machine learning to address these issues, prioritizing biological realism and intuitive insight. I am presently a senior Ph.D. candidate in Joseph Paton's lab and have also engaged in multiple artistic collaborations that have allowed me to explore alternative means for articulating these intuitions.


Selected Publications

"Representation learning over latent state policies" - Gonçalo Guiomar, Joseph J. Paton, Daniel McNamee (In Progress)

This project aims at understanding how acting in the world leads to a change in perception and how this could be adapted to a Reinforcement Learning framework based on Variational Inference.

"Action suppression reveals opponent parallel control via striatal circuits" - Bruno F. Cruz, Gonçalo Guiomar, Sofia Soares, Asma Motiwala, Christian K. Machens, Joseph J. Paton (2022). Nature, 607, 521-526

Built a multi-agent Reinforcement Learning model that is able to reproduce behavioral and neurophysiological data of mice in a time interval discrimination task and provide predictions for future experiments.

"Astrophysical Constraints on the Bumblebee Model" - Gonçalo Guiomar, Jorge Páramos (2014). Phys. Rev. D, D 90, 082002

Derived the strongest constraints for the existence of Dark Matter in the Sun using a symmetry breaking perturbation of Einstein's field equations.


Artistic Works

"Atavic Forest" within Latent Spaces (2022) and in collaboration with Jonathan Saldanha and Lunaring Art Colective (Tübigen).

This forest has been fully dreamt by Artificial Intelligence using state-of-the-art Generative Neural Networks trained with over 180,000 images in order to create a transversable space of visuals generated in real-time.
