Because my job at the University of Washington makes me a government employee, I try to follow state rules to use my UW email and mailing address for, but only for, correspondence related to my work as a UW faculty member (e.g., teaching and UW-supported research). Please don't just email both of my email addresses in an attempt to get my attention. If you think I have missed your message, go ahead and email me again. I miss things sometimes and I don't mind reminders.


Physical Addresses:

Please realize that I travel extensively so physical mail can be unreliable.

I currently live in Extraordinary Least Squares. Please visit that home webpage for details and directions. If you want to send postal mail, our address is:

2408 Delmar Dr E
Seattle, WA, 98102

My office is in the Community Data Science Lab in the Communications (CMU) building at the University of Washington in room CMU 306:

Community Data Science Lab
Communications Building (CMU), Room 306
University of Washington
Seattle, WA, 98195

The room can be tricky to find so please follow these step-by-step directions if you are coming to visit. If nobody is in the room, there's a chance I might be in the Community Data Science Meeting Room in CMU 333.

However, if you are going to send any postal mail or packages, please send to this to my UW mailing address:

University of Washington
Dept. of Communication, Box 353740
Seattle, WA, 98195

Communicating Securely

Whenever possible, I recommend that everyone communicating with me use encryption for authentication and to ensure that our conversations stay between us. For email, I use the GNU Privacy Guard (GPG).

GPG Keys:
