Tarun Kalluri

I am a fourth-year PhD student in the CSE department at UCSD advised by Prof. Manmohan Chandrakar. My research interests span the areas of computer vision and machine learning. I am interested in learning representations of images and videos from limited labeled data that are useful and transferable across a wide range of domains. Specifically, I work on problems in domain adaptation, transfer learning, few shot learning and open world learning.

Previously, I worked as a research assistant at Centre for Visual Information and Technology (CVIT), IIIT Hyderabad on various problems related to semantic understanding from large scale text and image data. I completed my undergraduate studies from IIT Guwahati in 2016, before working as a data scientist at Oracle Bangalore where I was part of team responsible for creating automated client-side cloud instance provisioning, upgrade and patching tools.
