My main research interests are in geometric group theory and probability (esp. intersection of those two fields). You can find my publications and more about my academic interests on research page.
I'm active in education of gifted children and organizing various interesting events. More on education & events page.
I'm also interested in many non-academic things, including books, music, drawing, mountains, improv, dreams, Japanese mahjong etc. Find out more on personal page.
