I am a first year PhD student in the department of Computer Science at Georgia Tech advised by Prof. Dhruv Batra and Prof. Zsolt Kira. Prior to this, I completed my Masters in CS at Georgia Tech advised by Prof. Dhruv Batra and Abhishek Das. I also closely collaborate with Erik Wijmans and Eric Undersander during my time as a MS student.

Broadly, I am interested at the intersection of Computer Vision, Robotics and Reinforcement Learning. My long-term research goal is to develop general scalable algorithms and efficient systems to train embodied agents that exhibit emergent intelligent behavior to accomplish goals in diverse real-world environments.

During my MS, I was fortunate to intern at Allen Institute of AI (AI2) in Summer 2023 with Luca Weihs and Kuo-Hao Zheng on common-sense and context-based reasoning for embodied agents. At Mitsubishi Electric Research Laborateries (MERL) in Summer 2022 with Anoop Cherian on building embodied agents for navigation and interaction in simulated environments that leverage 3D scene graphs for effective scene understanding.

Previously, I spent a year working as a Research Intern in Computer Vision and Machine Learning Perception Lab at Georgia Tech advised by Prof. Dhruv Batra and Prof. Devi Parikh. I also lead an open source organization, CloudCV, where we are building several open-source softwares for reproducible AI research.

Leading open source platform for evaluating and benchmarking AI models. We have hosted 200+ AI challenges with 18,000+ users, who have created 180,000+ submissions. More than 30 organizations from industry and academia use it for hosting their AI challenges. The project is open source with 130+ contributors, and 2M+ yearly pageviews. Some of the organizations using it are Google Research, Facebook AI Research, DeepMind, Amazon, eBay Research, Mapillary Research, etc. and research labs from MIT, Stanford, Carnegie Mellon University, Georgia Tech, Virginia Tech, UMBC, University of Pittsburg, Draper, University of Adelaide, IIT-Madras, Nankai University, etc. also use it to host large AI challenges like AlexaPrize on it. It's forked versions are used by large organizations such as World Health Organization, Forschungszentrum J├╝lich (one of the largest interdisciplinary research centres in Europe), etc. for hosting their challenges instead of reinventing the wheel.


Fabrik is an online collaborative platform to build, visualize and train deep learning models via a simple drag-and-drop interface. It allows researchers to collectively develop and debug models using a web GUI that supports importing, editing and exporting networks to popular frameworks like Caffe, Keras, and TensorFlow.
