My office is in PSY (64 Cummington Mall), Room 228C. It isn’t the easiest place to find, but follow these directions to get to Dr. Sullivan’s office and then look to your right — I’m the next door over.

The quickest way to get in touch is by either email or IM to If it’s urgent, give me a ring at 202-567-7362; note that my phone’s ringer is often not on (especially during lectures), but you can leave a message.

A note about privacy. If you IM or use voice on my 202-567-7362 number, you should be aware that this is a Google Voice number, and Google will both scan the text or voice message and store that information for an indefinite period of time, according to their terms of service. If you want to communicate with me securely, please use Signal (see the Privacy tab under About, above).

Here are my office hours for Fall 2018. No appointment is needed, just drop by. You also can speak with your TF during discussion sections.

Tuesday 11:00am – 12:00pm
Wednesday 1:00pm – 2:30pm
