My email is     yluan      @impan.pl

My older email   yuzluan      @ucdavis.edu    will soon be outdated. 

My office is 317 at IMPAN.

Please don't hesitate to send me an email to talk to me about math. I'm also happy to meet either in person or over zoom. Usually I'm not busy unless I'm traveling, and I should be able to find an one hour slot for you within the next day or two once I see your email.
