PhD Student

Carnegie Mellon University


I am a first year PhD student in Robotics Student at Carnegie Mellon University working with Prof. Katerina Fragkiadaki. Previously, I received M.S. in Robotics from Carnegie Mellon University advised by Prof. Katerina Fragkiadaki and B.E. in Computer Science from BITS Pilani, Pilani Campus where I spent one year working with Prof. Katerina Fragkiadaki as a research assistant in Machine Learning Department, Carnegie Mellon University.

I am interested in Computer Vision and its application to embodied learning. Lately, I have been interested in relationship between various visual modalities: how are 2D, 3D and video modalities connected together? How can one benefit the other? In my free time, I love listening to podcasts and lectures related to philosophy and ethics (My recent favourite). I also like reading fiction, watching (and playing) cricket and travelling.

Virtual MLC office hours (open to everyone): I dedicate two hours every week to mentoring newcomers in the fields of robotics, computer vision, and machine learning. If you're new to these areas and need help with research, grad school applications, or anything else, please feel free to book a slot.

Research Intern


May 2022 – August 2022 Cupertino, California, USA

Graduate Research Assistant

Carnegie Mellon University

Aug 2021 – Present Pittsburgh, Pennsylvania, USA
With Prof. Katerina Fragkiadaki, I am working on language grounding in static 2D and 3D scenes, robot manipultation following language instructions, and instruction following in indoor household environment.

Research Associate

Carnegie Mellon University

May 2020 – Jul 2021 Pittsburgh, Pennsylvania, USA
Under the supervision of Prof. Katerina Fragkiadaki, I worked on enabling an embodied agent to learn about objects without ground truth supervision in an unseen 3D environment just by moving around.

Research Assistant


Aug 2019 – Apr 2020 Rajasthan, India
As a research assistant, I worked under the guidance of Prof. Pratik Narang in computer vision. My team and I proposed a novel architectural design that improved the performance of previous methods by a substantial margin.
