Industrial Collaborations:

SlipStream Data: In April 2000, I co-founded a technology company called SlipStream Data which deals with acceleration of content delivery to internet applications such as email, web browsing, e-commerce, B2B (business to business) systems on low bandwidth networks such as dial, wireless, and satellite networks even under poor RF conditions. SlipStream received multiple rounds of venture funding and was profitable within three years from its inception. The company grew from size zero to about seventy employees in 2005 when its acceleration products were being used in about 40 countries at about 2000 Telcos and ISPs such as AOL US, Netzero, AOL Canada, Bell Canada, Telus, Alliant, Wannadoo (France), Bharati Telecom(India), CCPower (China), Telefornica (Latin America). A significant portion of my research finds its dissemination through SlipStream. In 2006, SlipStream was acquired by Research in Motion, the makers of Blackberry smart phones. SlipStream currently operates as a subsidiary of Research in Motion. My involvement with SlipStream and RIM is continuing.

In the past, I have provided consulting services to several large technology companys such as IBM Canada, ISOPIA (acquired by Sun Microsystems), Bell Canada, Nortel, Research in Motion.
