  • April 2022 - Our work on Snooping neural network is featured in a CACM news article!
    Our prototype shows it is possible to extract both the high-level network topology and detailed hyperparameters. Read the blog here.
  • March 2022 - Our Audio-driven Gesture Animation paper was accepted to CVPR 2022!
    Synthesize high-quality videos via reenactment from novel video motion graph.
  • Feb 2022 — I am promoted to Senior Research Scientist!
    This would not be possible without my interns, collaborators, and Adobe colleagues! Thank you all!
  • Jan 2022 - I hosted a panel discussion with Adobe Researchers on how to work with interns and what makes for a great internship.
    Watch it here!

Internship and collaboration at Adobe Research (flexible schedule in 2023): if you are a PhD student interested in a research internship on audio/video understanding and its applications, please send me an email with your CV and a summary of your research interests.


I am a Senior Research Scientist at Adobe Research. I got my PhD in Computer Science from Columbia University and BEng from HKUST.

I am interested in audiovisual cross-modal analysis and synthesis for accessibility. Leveraging tools from computer vision, graphics, deep learning, and HCI, I focus on novel creative authoring/editing experiences for everyone. My past research and engineering has been recognized by an Emmy Award 🏆 for Technology and Engineering (2020), two Adobe MAX Sneaks Demos ✨(2019 , 2020), an ACM UIST Best Paper Award 🏅 (2017), an Adobe Research Fellowship 🎓 (2017), a NVIDIA PhD Fellowship Finalist (2017), a Shapeways Educational Grant 🧧 (2016), and an HKUST academic achievement medal 🥇 (2013). I have served as international program committee members for Eurographics 2020/2021, Graphics Interface 2020, and ACM Multimedia 2019, and as reviewers for various academic conferences including SIGGRAPH, CVPR, ICCV, UIST, CHI, etc. I am also serving as the Adobe Fellowship program co-chair with Valentina Shin, recognizing outstanding PhD students conducting exceptional research.

I’m always looking for interns and collaborators to work on research projects leading to publications/patents/product features. Please feel free to reach out to learn more.
