Hi

I am a researcher with strong passion for neuroscience, biologically-inspired artificial intelligence and robotics. I currently work both at Emotech and the Wellcome Centre for Human Neuroimaging in UCL. I recently left (after 8 years) from department of Computing of Imperial College London where I was mainly working with Prof. Murray Shanahan (and some other amazing people) and, at some point, as the principal investigator of the six-partner EU project TimeStorm. I received my PhD in computational neuroscience under the supervision of Prof. Shanahan, where I investigated the relation between brain oscillations, our ability to select actions and Parkinsonian tremor. In this website I share some information about my work, my interests and my thoughts. If you find anything interesting, feel free to drop me a line :)

My research

A general theme of my work has been to investigate how human-like aspects of cognition can emerge from computational models and test hypotheses via software or physical embodied agents (such as neuromorphic robots). I've worked on both bottom-up models (e.g. spiking neural networks), top-down models, or the combination of the two (e.g. the robot Olly). Some cognitive abilities of the brain that have been bothering me, include the brain's ability to:

  • select between different salient actions (with emphasis on cortical oscillations and the basal ganglia),
  • perceive time,
  • remember particular events (episodes) and use them to learn the world,
  • globally access and process information concurrently,
  • simulate potential future scenarios and generate predictions to drive decisions,
  • implement Bayesian inference via predictive coding.

In my PhD, I focused on how action selection occurs in the brain, when the latter is viewed as an oscillatory dynamical system, how important are the dynamics of individual neurons for this purpose, as opposed to those of neural circuits, as well as how the action selection mechanism of the brain might be responsible for the basic motor symptoms of Parkinson's disease, such as the resting tremor.
