Biography

I am a Machine Learning Scientist at the Expedia Group, working with the content data science team. We work on development of platforms and models that handle curation, ranking, and recommendation of user generated content (text, images, tags, ratings, etc).

Previously, I was a Reserch Scientist at Nokia Bell labs, Cambridge UK, working with the social dynamics team, where I did blue sky research around ideas to quantify human processes from large scale data.

I am mainly interested in research problems that pertain to building strong representations of human behaviour from data, using methods from complex networks, machine learning, and computer vision.

I was a King's India scholar at King's College London, where I worked on my Ph.D. in computer science at the Department of Informatics, under the guidance of Dr. Nishanth Sastry.

I have graduated with a Masters of Science (M.S.) degree from University of California at Santa Barbara USA, majoring in signals processing and networks, and a Bachelors of Engineering (B.Eng) from University of Pune India, majoring in Electronics engineering .

Research Scientist

Nokia Bell Labs

Jun 2019 – Jul 2021 Cambridge, UK
As a member of the Bell labs social dynamics team, I have been working on questions that try to redefine our relationships with data. I primarily work on problems dealing with machine learning and statistical inference with a stress on impacts on healthcare and urbanism. The work generally involves mathematically modelling an off-line phenomenon through the online data that it generates.
