About

Hi, I am Jian (James) Wang, currently a Staff Research Scientist at Snap Inc. I am now leading the Snap Research NYC team. I obtained my Ph.D. degree from Carnegie Mellon University, advised by Prof. Aswin Sankaranarayanan and Prof. Srinivasa Narasimhan.
I'm mainly interested in Computational Photography/Imaging, including image/video quality enhancement, image/video editing/manipulation, and generations. I was managed by Shree K. Nayar and Guru Krishnan in Snap. Shree gave a nice keynote about our (unpublished) work in ICCP 2022 which includes my works, see here video link.
I am looking for academic collaborations; if you are interested in working with me on academic research in Computational Imaging, Computational Photography and Computer Vision, please contact me via email by including your CV. 我可以给你提供学术指导和学术ideas.

News

  • I gave a keynote talk on CVPR 2024 MIPI workshop titled "Towards A Better Camera in the App and AR Glass".
  • I will serve as an Area Chair for NeurIPS 2024, ICLR 2025, CVPR 2025.
  • We are organizing ECCV 2024 workshop "3DVeComm", 3D Vision and Modeling Challenges in eCommerce link.
  • I gave a poster, Towards a Better Camera, to briefly introduce our work (of one year ago) in CVPR 2024 AC workshop; see here.
  • 🔥🔥 We have multiple openings for internship in 2024 (Summer, Fall or Spring), see flyer. If you are interested, please send me an email. For international students outside of the US, we can help them apply for J-1 visas.
    • Why intern with us? — We have exciting and real research problems from our product Snapchat App (a multimedia instant messaging app with 406 million daily active users, Q3, 2023) and future product Snap Spectacles, our industry-leading AR glasses. We are responsible for every intern by carefully designing each project to fulfill the intern's interest and expected outcome from the internship. The intern has a chance to have product impact, academic impact, or both. In the past five years, each intern had one first-author paper in top-tier conferences 🤗. Besides, interns will have a competitive salary and housing stipend, and have the opportunities to visit many internet celebrity check-in places in New York City 😀. The internship experience could also help students later find full-time jobs in the US.
    • In the past, our group were fortunate to host a group of talented students. They had great experiences and outcomes.
