About Me + My Interests

Currently I am the director of data science in XBOX/Surface/Studios marketing working on consumer intelligence for games, entertainment and devices.

I have worked on a variety of problem spaces involving Big Data. Engineered intelligent solutions using machine learning in various domains - cloud services such as OneDrive/Sharepoint, search, recommendations, social experiences, online advertisements, knowledge bases, text mining and speech/speaker recognition, in the following roles:

Recent Keynote Speech "Machine Learning & Data Science for XBOX" at Predictive Analytics Innovation Summit, Feb 18-19th, San Diego.

Some recent projects for which I managed the applied research team:

Much of this work was on "finding connections that interest you". It is about helping people discover things that interest and delight them & help them make better decisions. For this, I have used data mining, machine learning, semantics & recommendations. I have worked extensively in various aspects of this space:


  • Interest Graphs.  One simple example of what we have enabled is if you search on Bing for "meat dress costume" we connect you in the Sidebar to Facebook friends who like Lady Gaga.

Bing for meat dress costume, find Facebook friends who like Lady Gaga


  • In the Knowledge Web team, we built the very first large scale knowledge graph in Microsoft, which has become the seed for Bing's own knowledge graph. On top of this, we built experiences for discovery of knowledge. The example here also shows ads that are semantic.

  • Our first knowledge base was in personal finance, and was the primary driver for Bing Finance. One example of what we did was to provide alternate recommendations when searching for a stock - other "higher dividend paying", "top buy rated in the same sector", "having similar PE ratio" etc. which helped people make better stock picking decisions

  • We also built recommendation apps that advanced a "push" paradigm (restaurant recommendation on a mobile phone & video recommendation on tablet). They had well-integrated social experience (Facebook friends), worked on "context genomes" and "taste mash-ups"
