I am a professor at the University of Warsaw. I am an expert in Discrete mathematics, Algorithmic game theory and Social choice, and most of my edits concern this topic. As an employee of a public university, popularisation of science is a part of my job, and in this sense my edits are paid. However, the topics and content of my editing here is not influenced by any organisation whatsoever, and I do not participate in paid edits for specific articles or specific content. I am also not evaluated nor paid based on the content that I contribute to Wikipedia. In order to avoid my assessment based on such contributions, I write the articles anonymously and do not disclose my identity.
