There, there.

Hi there! I am Zhou Xian, a final-year PhD student in the Robotics Institute at Carnegie Mellon University, advised by Katerina Fragkiadaki. I am broadly interested in robotics, computer vision and world model learning. Prior to CMU, I completed my Bachelor's degree at Nanyang Technological University in Singapore, working with Pham Quang Cuong and I-Ming Chen. I have also spent wonderful summers as a research intern at Meta AI with Akshara Rai, and at MIT-IBM AI Lab with Chuang Gan.

My current research focuses on building unified neural policies and simulation infrastructures for scalable robot learning.

I am also an independent landscape photographer, with a special interest in aerial and celestial photography. I was affiliated with the Visual China Group (视觉中国) and was one of the top 10 contributors on My images have received tens of millions of views and near a million downloads across platforms like Unsplash, Notion, Trello, Medium, etc. Here are some of my personal favorite photos of all time.

I get emotional watching the Milky Way dance, every single time.
