Shlok Mishra

I am a Ph.D. student at University of Maryland in the department of Computer Science. I am advised by Prof. David Jacobs working on problems in Computer Vision and Machine Learning. I also obtained an MS in Computer Science from University of Maryland, College Park.

I primarily work in Self-Supervised Learning and Generative models in Computer Vision. I have done multiple internships at Google. In Summer of 2022, I worked with Dilip Krishnan on Self-Supervised learning. In Summer 2021 I worked with Christian Haene and Hossam Isack on Generative models. In Summer 2020, I worked with Kuntal Sengupta, Vincent Chu and Sofien Bouaziz on Spoof Detection. I have also done 4 student research internships and have been working in Google for last 2.5 years.

Research

I am interested in computer vision, machine learning. Specifically, my current research interests are in Self-Supervised learning, Generative models and building models which can do learn both generative and discriminative features.

Service

Serving as reviewer for major machine learning and computer vision conferences (CVPR, Neurips, ICLR, AAAI, ECCV, ICCV, etc) and journals (TMLR, TIP , CVIU, IJCV). In the past I have also served in NLP conferences (ACL, EMNLP).
