Ayush Gupta

I am a Ph.D. student at Johns Hopkins University in the department of Computer Science. I am advised by Prof. Rama Chellappa working on problems in Computer Vision and Machine Learning. I am supported by an IARPA grant, BRIAR. I am currently working on problems related to fine-grained computer vision and metric learning.

Previously I obtained a B.E. in Computer Science from Birla Institute of Technology and Science (BITS), Pilani. At BITS Pilani I was working under the guidance of Prof. Poonam Goyal on generating natural language descriptions of videos, and Dr. Yogesh S Rawat on Gait Recognition.

Research

I am interested in all things computer vision and machine learning. Specifically, my current research interests are in Gait Recognition and Person Re-ID, where I am working on identifying people for long-range, turbulent in-the-wild data.
