IISc and its alumni started this series of conferences with the first one in Santa Clara, California, in 2007 (Flickr pics) -- just a year before, and possibly as a prelude to, the Institute's Centenary Celebrations. The second edition followed in due course in 2013, this time in Chicago, Illinois.
The third edition of this Conference is coming home to the Institute. The dates are: 26-28 June 2015.
It is a sign of the times that this Conference gets announced on social media well before the conference website is ready. Much as I hate to send you to any of these time sinks, here are the links to the community / group pages:
If Twitter is your social media poison of choice, the relevant hashtag is #IIScAGC.
