My user name is mpj and my domain is cs.pdx.edu. Join the two of these together with an at sign, and you will have my email address. (And perhaps, by writing my address in this cryptic form, I will not get quite so much spam!)

I receive a lot of email, and I'm always very busy. So, while I always try to reply as promptly as I can, please be aware that there might be some delay.
