Prajwal Paudyal


I am a Ph.D. Student in Computer Science at Arizona State University

The focus of my research is finding solutions and building systems for effective recognition of visual languages. Here is a small video back in 2016 for a system Sceptre I built. 

My interests are in Natural Language Processing, Computer Vision, Visual Languages and Machine Learning. Recently my work was features by a few magazines. (MIT Tech Review). I also received the Outstanding Research Award, and the Caulkins Communication Award for exemplary work in connecting graduate students. 

I am pursuing my Ph.D. under the supervision of Dr. Sandeep Gupta and the main focus is solving the main problems for Sign Language Recognition. For this I focus on American Sign Language(ASL) and have started to learn a bit of ASL myself. Now that is fun! 

Currently the research work I am actively involved in are:

  • Learn2Sign: A interactive tutor for Sign Language Learning
  • SignType: A novel HCI method for interacting with computers. 
  • GRUSI: Recognizing human actions and gestures using representative Images. 

These projects are still in the pipeline for publishing, so more details on them soon. 


Contact me for research collaborations and/or job internship opportunities specially if you have something going relating Sign Language Recognition and engagement with the Deaf community.

I’ll pull my publications here soon, but meanwhile here is a link to my Google Scholar’s page. It is pretty up to date except for a latest Journal published at TiiS
