He had visiting appointments at Cornell University (2004-2005), Harvard (2007, 2011-2012, 2015-2016, 2019-2020), MIT (2015-2016, 2019-2020), and University of California, Berkeley (2008), where he studied software engineers' workplace culture.
His current work is focused on collaborative society (2020, "Collaborative Society", MIT Press, co-author A.
