About

Hi, I am Jian (James) Wang, currently a Lead Research Scientist at Snap Inc. I obtained my Ph.D. degree from Carnegie Mellon University ECE department, advised by Prof. Aswin Sankaranarayanan and Prof. Srinivasa Narasimhan.
I'm mainly interested in Computational Photography (e.g., image/video restoration/enhancement, image/video generation, image matting and compositing, novel view synthesis, multimedia), Computational Imaging (e.g., novel cameras/sensors/wearables/displays for AR/VR/HCI, active 3d sensing, creative consumer imaging devices), and Computer Vision (e.g., physics-based vision, low-level vision, 3d vision).
I'm managed by Guru Krishnan and Shree K. Nayar in NYC research lab 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 Shree gave a nice keynote about our (unpublished) work in ICCP 2022 which includes my works, see here video link.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

  • 🔥🔥 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.
