Feel free to slide under my door any routine paper that requires my signature -- DO NOT knock on the door or enter. Unless you find it very difficult, place a small explanatory covering note with your emailid somewhere. Do NOT send email in such cases.

1. If you are a person with IIT affiliation,

   • If there is something that takes less than 2 minutes, and I know you, please walk in -- feel free to push the door in and walk; as a courtesy, knock a couple of times before pushing the door. Do NOT send email in such cases.

   • If I do NOT know you, please see me during office hours.
   • If you are my (BTP, DDP, MTP, seminar, Ph.D, summer) student, or project staff, then you know you can contact me at any time. The best bet is to pick up the phone and call me. Feel free to call me at home. That said, you should see my collaborator schedule and meet me during those hours.
     • Above points also applicable to any senior TA assigned to me but use the course schedule.
   • If you are taking my class, please see me during class office hours.
2. If you are outside IIT,
   • and we have never exchanged email before, write to me by affixing the domain name acm dot org after sharat (something like ) (you might want to check out this page first though). There is no guarantee that I will reply your email although I usually do.
   • and we have exchanged emails before, please do send me mail at my work (IIT) address to proceed further.

I am usually in one of two places. (See directions)

• I am usually in room A-202 Rekhi Building
• Otherwise I am in the lab (aka ViGIL, Phone x4709). This lab is on the 4th floor of the new CSE department building -- also called -- -- saracastically as Taj Mahal (next to KR Building)
