Mobile: +358 40 754 5660 Skype: kallemik (skype being "on" does not mean that I'm there, but you may try) Email: Kalle.Mikkola@iki.fiwww: https://www.math.aalto.fi/~kmikkola/
Email and mobile phone are the best
ways to reach me (call+SMS+email is quicker than just 1 of them, in the average). Most of my old email addresses work as well, too (including aalto.fi).
Please, resend your message if I do not react quickly enough.
If you leave the subject field empty (or use typical spam words or many links with little text), my anti-spam robot might catch your email.
