I am not on Facebook, Twitter, Google+, LinkedIn, or similar things
(and emails with those words are filtered to trash).
I do not blog (but I freely share my opinions with anyone who feigns
interest).
I am rarely available by telephone.
Currently I am not accepting any new graduate students.
I try to check my email frequently. Sometimes, especially when traveling, it is not easy and I may be offline for a day or two.
