I'm interested in discovering and learning about the world around (and in) us, irrespective of discipline.
Currently, my research interests are in incorporating ecological and social considerations into macroeconomic models, using techniques like stock flow consistency, input-output tables, and system dynamics. I also maintain my earlier interests in the areas of learning in the brain and in artificial neural networks, specifically online and local learning rules, reinforcement learning and system identification.
My publications and related code page has my articles classified by subject area. However, my Google Scholar page typically has a more up-to-date list of my publications.
Since July 2026, I'm a Researcher at the Institute for Ecological Economics, Department of Socio-Economics, Vienna University of Economics and Business -- see my official page. I also continue my association with the University of Sheffield as a Visiting Academic.
