I served on the WMF Board of Trustees for a decade (2015-2025). Over the years, I've also been a steward, as well as an administrator, bureaucrat, or checkuser, and mediator on Polish Wikipedia. I'm sporadically present as a regular user also on Wikimedia and commons. 2011-2012 I served on the Ombudsman commission for Wikimedia projects. I stepped down from OC in 2012, when I was elected to be a steward of Wikimedia (I stepped down in 2016). 2012-2015 I was on the Funds Dissemination Committee (and I have been its elected chair for three consecutive terms).
קום בחור עצל וצא לעבודה I have been around this mortal coil for about 1574145268 seconds. I am a tenured full professor of management. My interests include action research, organization studies, knowledge intensive work, open collaboration communities, professional culture, ethnography. I am a constructivist doing qualitative research. Years 2004-2005 I spent as a Fulbright scholar at Cornell University. In 2007 I spent a semester as a visiting scholar at Harvard University. In 2008 I spent a semester as a visiting scholar at University of California Berkeley. 2011-2012 I'm spending as a visiting scholar at Harvard Law School. For five years I practiced aikido, which I had to drop because of knee problems. Since 1995 very irregularly I've been practicing karate, alternating Gosoku-ryu, shotokan, Wado-ryu and, sporadically, Enshin. Later I turned to krav maga, became an instructor, and eventually in 2019 received a black belt (Expert 1 grade from Krav Maga Global organization). Since 2021 I've turned to Brazilian Jiu Jitsu, which I train regularly 3-4 times a week.
