Ciao! I'm Pengsheng Guo.

I am a research scientist at Apple, collaborating with cross-functional teams to create captivating virtual reality experiences for Apple Vision Pro.

I conduct research in multiple domains, including generative model (image, video, 3D), neural rendering, multi-task learning, and efficient machine learning.

I worked with Professor David Held on Reinforcement Learning during my graduate studies at CMU Robotics Institute. I worked with Professor I-Ming Chen on Robotic Manipulation during undergrad at NTU, Singapore.
