EXPERIENCE

• I'm currently an applied scientist at Amazon Go, on the algorithms team for the Dash Cart. We recently had a public launch, and you can see a nice video about it here.


• I completed my Master's in Computer Science at UMass, Amherst in 2019.


• In Summer, 2018, I had the opportunity to work with Bob Price in the Interaction and Analytics Lab at Xerox Parc, where I investigated techniques few-shot learning and training object detectors with less labeled data.


• As an intern at Intel, Bangalore, I worked with Anbumani Subramanian and Subramanian Chidambaram on real-time classification and segmention of hyperspectral images.


• As a part of the Aspiring Researcher Program, I worked with Prof. James Davis at UC Santa Cruz and Rajan Vaish, on analyzing crowdsourcing techniques for machine learning related data collection:
