Welcome to my home page!

I am a Principal Research Scientist at the Center for Collective Intelligence, a Research Scientist at the University of Zurich, and a Visiting Professor at the Nagoya Institute of Technology.

I do research on collective intelligence (also known as social or human-centered computing). I have over 200 publications in this area, with 7000 citations and an h-index of 40 on Google Scholar, in addition to over 7000 downloads on ResearchGate and 6000 downloads on SSRN.

I'm on the editorial boards for CERA, AI EDAM, JSMO, CSCW and Knowledge Management and e-Learning, journals, and have served on the program committees for numerous conferences on artificial intelligence and collective intelligence

I am deeply committed to solving real-world problems, especially in the sustainability and participatory democracy realms.

I also have a long-standing commitment to engagement with the international research community: I've hosted many international visitors in my lab at MIT, and have done extended research visits in Japan, Hong Kong, France, Italy, Spain, Brazil, Switzerland, and New Zealand.
