Jiemin Fang (方杰民)¶

I am a senior researcher and assistant chief expert at Huawei of the TopMinds program, leading a small group that mainly works on 3D/4D reconstruction and generation. My research interests also include neural rendering, representation learning, neural architecture design/search and AutoML.

I obtained my PhD and BE degree from Huazhong University of Science and Technology (HUST) in 2023 and 2018 respectively, supervised by Prof. Wenyu Liu and Prof. Xinggang Wang.

If you are interested in intern/full-time positions of our group or any other collaboration with me, welcome to contact me via email.
