Dariusz Jemielniak is a Wikipedian, Full Professor of Management at Kozminski University, and an entrepreneur (having established the largest online dictionary in Poland, ling.pl, among others). 

Dariusz currently serves on Wikimedia Foundation Board of Trustees. In his academic life, he studies open collaboration movement (in 2014 he published ""Common Knowledge? An Ethnography of Wikipedia"" with Stanford University Press), media files sharing practices (among lawyers and free knowledge activists), as well as political memes' communities. 

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. Przegalinska), a phenomenon of technology radically enhancing a natural trend of people to cooperate, visible in peer-to-peer production, uberization, online cooperatives, but also in meme culture, and better explaining the emerging change than the buzzword ""sharing economy"".

He is also continuously interested in combining qualitative and quantitative methods in digital society research (2020, ""Thick Big Data"", Oxford University Press).

He is currently a PI in three projects, totalling to ~2.5 million USD, and focused on vaccine misinformation online, climate change denialism online, and bot detection. 

He also is a co-founder and CEO of InstaLing, a free platform supporting language teachers currently used by 220k people, and a chief community strategist at Foap, a platform making photo and video creators get a fair share of royalties from marketing campaigns, with a community of over 3 million users.
