I am an associate professor in the
Department of Computer Science at
Binghamton University.
My research areas include Internet immersive streaming, multimedia systems,
mobile computing, and edge/cloud computing.
My current work addresses system-level challenges in future immersive streaming
technologies such as 360-degree and volumetric video delivery.
I am looking for motivated PhD students. If your research interests
are aligned with mine, please feel free to send me your CV.
News: My PhD student, Chao Zhou, is a
winner of the
Graduate School Distinguished Dissertation Award. Congratulations Chao!

Code
ffmpeg360 is a tool for rendering 360-degree videos and converting
between projection types. Operations are performed on the GPU within a fork of
the FFmpeg utility. Check it out on GitHub at: ffmpeg360
360projection renders 360-degree images and converts
these images among equirectangular, cubic, and offset cubic projections. Check it out on GitHub at: 360projection
