Devendra Singh Chaplot

I am a Research Scientist at Mistral AI working on building the next generation of AI models. Earlier I was a Reasearch Scientist at Facebook AI Research where I worked at the intersection of Computer Vision and Robotics. I received my Ph.D. at the Machine Learning Department, School of Computer Science, Carnegie Mellon University. During my Ph.D., I worked with Prof. Ruslan Salakhutdinov on Building Intelligent Autonomous Navigation Agents. I also worked closely with Abhinav Gupta and Saurabh Gupta. Prior to joining CMU, I graduated from IIT Bombay, India with a B.Tech in Computer Science & Engineering and a minor in Applied Statistics in August 2014, where I worked with Prof. Pushpak Bhattacharyya. I also worked for about a year at Samsung Electronics HQ in South Korea.
