I am a sociologist of the Internet, a graduate of the University of Pittsburgh, and a professor in Korea at Hanyang University.

I am most active at English Wikipedia - please see my user page there. I registered my account there c. 2004, and as of 20 years later, I am in that project's Top 200 most active editors, with 200k edits and 2k+ articles created, including hundreds featured on the Main Page as Did You Knows and dozens Good and Featured Articles. I am also reasonably active on Polish Wikipedia, where I've created few hundred articles as well.

I have published many academic papers on Wikipedia () and I am one of the pioneers of teaching with Wikipedia activity at universities (, ). My students contribute numerous articles to English, Korean and Chinese Wikipedia (see w:User:Piotrus/Educational_project_results for details).

I am an inclusionist.

My favourite part of meta: Research Committee (serious) and How to deal with Poles (fun)
