Indian scientists in NYC was initiated by Anirban Banerjee (Rockefeller U) and a bunch of other Indian grad students/ post-docs in the NYC area. The formation of this group was an outcome of meeting at Anuradha Lohia's presentation in NY where she discussed Wellcome Trust DBT fellowship opportunities. This group meets once a month or so in informal settings. You can join by emailing the owner for an invitation: http://groups.google.com/group/indian-scientists-in-nyc/
