Profile

Biography

Dr Dimitri Ognibene obtained his PhD in Robotics from the University of Genoa in 2009. Before joining the University of Essex, he has been performing experimental studies and developing formal methods for active social perception at UPF, Barcelona, as a Marie Sk?odowska-Curie COFUND Fellow; developing algorithms for active vision in industrial robotic tasks as a Research Associate (RA) at Centre for Robotics Research, Kings College London; devising Bayesian methods and robotic models for attention in social and dynamic environments as a RA at the Personal Robotics Laboratory in Imperial College London; studying interaction between active vision and autonomous learning in neuro-robotic models as a RA at Institute of Cognitive Science and Technologies of the Italian Research Council (ISTC CNR). He also collaborated with Wellcome Trust Centre for Neuroimaging (UCL) to address the exploration issue in the currently dominant neurocomputational modelling paradigm. Dr Ognibene has also been Visiting Researcher at Bounded Resource Reasoning Laboratory in UMass and at University of Reykjavik (Iceland) exploring the symmetries between active sensor control and active computation or metareasoning. Dr Ognibene presented his work in several international conferences on artificial intelligence, adaptation, and development and published on international peer-reviewed journals. Dr Ognibene was invited to speak at the International Symposium for Attention in Cognitive Systems (2013 and 2014) as well as in other various neuroscience, robotics and machine-learning international venues. Dr Ognibene is Associate Editor of Paladyn, Journal of Behavioral Robotics, and has been part of the Program Committee of several conferences and symposiums.

Research interests

Artificial Intelligence (Ognibene & Demiris 2013, Nivel et al 2014)

Cognitive Neuroscience (Ognibene et al 2017, Friston et al 2015, Pezzulo & Ognibene 2013)

Proactive Social Robotics (Ognibene & Mirante, 2018; Ognibene & Demiris 2013, Ognibene et al 2013, Petit et al 2013)

My research interests entail the principles underlying adaptive social behaviour in complex conditions with particular attention to anticipative skills and exploration in unknonwn environemnts. My research covers both biological and artificial agents as well as physical (visual and multimodal) and virtual environments as social media and virtual reality. I use machine learning methods, both (deep) neural and probabilistic models, to create agents as well as to study and predict their behaviours.
