Xinqi Liu | 刘鑫琦

I am currently an Assistant Professor at School of Robotics and National Engineering Research Center of Robot Visual Perception and Control Technology, Hunan University (HNU) . Previously, I worked at Department of Computer Vision Technology (VIS), Baidu Inc. I obtained my Ph.D. degree from School of Mechanical Engineering, Zhejiang University , advised by Prof. Jituo Li.

My research focuses on 3D digital humans, 3D vision, and embodied intelligence.

We are looking for students and research assistants. Please do not hesitate to email us if you are interested in working with us.

本课题组目前正在招收硕士研究生、研究助理和访问学生，同时欢迎有志向的本科生提前参与科研工作。

本课题组注重平等交流，沟通融洽，与浙江大学机械学院、浙江大学机器人研究院、湖南大学机器人学院的其他导师团队、以及百度视觉技术部算法团队具有紧密合作，能够提供共同学习讨论，科研交流，和企业合作的机会。

如果您对Computer Vision, 3D Digital Human, Embodied Intelligence感兴趣，请发送邮件至邮箱。

另外，欢迎各位老师、学生和企业与我们联系开展科研合作！
