About

Overview

www.pinotsislab.com Dr Dimitris Pinotsis is a Senior Lecturer (Associate Professor I) at the Centre for Mathematical Neuroscience and Psychology and the Department of Psychology at City, University of London.

He is also a Research Affiliate at the Picower Institute for Learning and Memory and the Department of Brain and Cognitive Sciences at the Massachusetts Institute of Technology (MIT), where he worked between 2016 and 2018.

Dimitris has also been a Senior Research Fellow at UCL’s Wellcome Trust Center for Neuroimaging where he worked with Karl Friston and a senior Scientist at MIT where he worked with Earl Miller. He holds a PhD in Mathematics and an MSc in Theoretical Physics from the Department of Applied Mathematics and Theoretical Physics (DAMTP) of the University of Cambridge, UK.

Dimitris' research has been funded by UKRI, US Air Force Office of Scientific Research, EPSRC and the Wellcome Trust. It spans diverse areas including machine learning, the analysis of big data in neuroimaging, theoretical neurobiology and nonlinear systems in mathematical physics.

In recent work, Dimitris exploits deep neural networks and hierarchical Bayesian inference to understand the causes of neurological and psychiatric disorders. He also exploits brain recordings to build better artificial intelligence algorithms.

Dimitris is an Expert Reviewer for US Air Force Office of Scientific Research, the Austrian Science Fund and the Italian Ministry of Health. He tweets at @dimitrispp and shares his work at researchgate.net

Interested students please get in touch. There are opportunities for theoretical and experimental projects in collaboration with colleagues at MIT, Harvard, UCSF, Toronto, UCL, King's and elsewhere.
