Contact Information

Here's some quick pointers on how to reach me. Basically, I prefer email over unscheduled phone calls or paper mail, but I do very much like scheduled calls and meetings. Unfortunately, I'm sometimes slow in responding to my correspondence. If it's urgent, text me or message my assistant (in a professional context), to call attention to your email. Other types of messaging - eg Twitter DM, Skype chat, Slack, Linkedin, etc - rarely get to me.

Email — Main — with asst.

Goes to me and my assistant. Use this (not my main email) for web forms -- e.g. for reference letters. My assistant does not handle personal matters or my schedule (so write me directly about these).



For public chat, but not DMs.

Phone, Cell, Text, & Fax

203 718-6559 — for "public" texts

My listed text number, best for calling attention to an email (via subject & sender), viz: Look for the email with subject "sending you check for $15M."

-x508 — for texts & calls

I have other numbers for texts and phone calls. 203 xxx-x508 is my main one. Use sparingly. Also, avoid calling or texting other numbers as I probably won't get your message. (More.)

mark.gerstein — for skype & zoom

Please don't try to "chat" with me here when not on an arranged call. (More.)

203 432 6105 — for nothing!

My official phone, which I rarely answer unless I'm expecting a call. Don't try; instead, contact my assistant or arrange a phone call with me over email.

x861 — for FAX

Still maintain. Email me if you want to send one.

Physical Location & Paper Mail

Bass 432A — office

If you want to meet in person (which I do like!), this is my office location. (See here for details.) You sometimes need authorization to get in the building after 6 PM. If so, arrange to call/text me, so I can meet you. Also, please announce yourself.

M Gerstein, Bass 432a, MBB, Yale U, New Haven, CT 06520

My correct paper mail address. I much prefer email to paper mail, so this will get a very slow response.
