I am currently investigating applications of Blockchain technologies for Supply Chain, Freight and Logistics, Food Safety and Provenance, etc. Interesting challenges abound in operating infrastructure and efficiency, business value and financial incentives, organizational dynamics and behaviors in blockchains, data standards and interoperability,  in situ blockchain applications, and in enabling data to be born on the blockchain.

Till recently,  as the Chief Scientist and Senior Manager for IBM Commerce Research I was responsible for creating innovative and scalable solutions for key problems faced by omnichannel commerce businesses.  Examples of these include Contextual Customer Engagement, Real Time Personalization, Local Events Marketing Kit, and Demand Forecasting. I conceived and championed the IBM Commerce Advanced Solutions HUB (CASH) that is leveraged for big data commerce solutions such as Local Event Marketing Kit and IBM Watson Order Optimizer. Early prototypes of my work CLAsSIC (Contextual Location Analytics for Smarter Commerce) led the vision for IBM's Metropulse offering (recent announcement). I worked closely with the world wide IBM Research Labs and IBM product teams that deliver platforms, analytics, and industry specific solutions.

I like to innovate and try to deeply influence both the industry and the academic communites, and transitively our society, with my efforts. 

Earlier impacts of my work to IBM products include location services, coupon wallets, and REST enablement of IBM WebSphere Commerce (which allows new shopping models such as exposing products directly in an ad), XC10 data caching appliances, and enterprise mashups and visual analytics.

I helped launch and define the agenda for the IBM Korea Ubiquitous Computing Laboratory that is now part of a growing IBM Korea Software Solutions Lab.  We explored several aspects of Device Symbiosis as part of this agenda.

Earlier, I pioneered novel concepts in mobile computing such as -  the Linux Watch (aka WatchPad), SoulPad, and Personal Mobile Hub with focus on health monitoring, Inverted Browsers (essentially modern mobile app model where the browser is included in the app), Mobile Loyalty for on the spot in store offers, a navigation system that was the first to provide photographs along with route information (precursor to Google Street View).

I also worked on architectures for IBM graphics accelerators and was also one of the chief software and system architects for the OpenGL® programming interface on the IBM RS/6000 workstations. Our implementation of OpenGL® was one of the earliest in the industry in 1993. OpenGL ES is now the dominant graphics API in smartphones.  I was a member of the team that defined the graphics instructions for an IBM Graphics Floating Point Engine (GFPE) based on the PowerPC™ architecture. SIMD instructions are now available on the PowerPC™ processors and are exploited by several graphics and media applications.

I was twice named an IBM Master Inventor (less than 0.06% of IBMers are named each year) and hold 102 US Patents and 174 patents worldwide. I am named on several IBM Research Accomplishments. I served as the Associate Editor in Chief for IEEE Pervasive Computing and guest-edited issues on Pervasive Retail, Healthcare, Energy Harvesting, User Generated Content and Virtual Machines and served on the Editorial Board for IEEE Transactions on Mobile Computing.  I have published more than 50 scientific papers and served on 25+ Program Committees for several ACM and IEEE technical conferences.

I obtained my PhD in Computer and Systems Engineering from Rensselaer Polytechnic Institute and my BTech in Electrical Engineering from IIT, Bombay. I have also completed a year long Micro-MBA program at IBM Research. I was elected a Fellow of the IEEE in 2008 for my contributions to pervasive computing. I am also a member of the IBM Academy of Technology. I have been fortunate to have my work covered by the world’s leading newspapers and appear on the covers of several technical publications and in analyst reports.
