About

Overview

I am a computational cognitive neuroscientist, working primarily in biological-based AI and, more in particular, in developing reinforcement learning models of the brain and on how such models can be applied to build AI technology and solve AI problems.

I am interested in learning processes, with emphasis on fundamental mechanisms shared across species and as applied to the development of AI algorithms and architectures. The theoretical core of my research is based on associative learning, a genuinely interdisciplinary framework able to offer new insights into a variety of topics, from neural connectivity to machine learning. My training as an experimental psychologist with near 15 years of experience in behavioural neuroscience allows me to synthesise natural and artificial approaches to cognition.

Currently my research is centred on using deep learning architectures and techniques to model associative learning as introduced in Mondragón, Alonso, & Kokkola (2017).

At City, University of London I have supervised to completion two PhD students: André Luzardo (The Rescorla-Wagner Drift-Diffusion Model, Oct 2017) and Niklas Kokkola (A Double-Error Correction Computational Model of Learning, Nov. 2017).

Starting May 2019, I am supervising Esther Mulwa (Building and Associative Model using Deep Neural Architectures).

New PhD students are welcome!

I direct the Centre for Computational and Animal Learning Research that aims at encouraging interdisciplinary research in learning and cognition by strengthening collaboration between learning theorists, biologists, neuroscientists, cognitive scientists, mathematicians, software developers and computer scientists.
