"The truth always turns out to be simpler than you thought."
Yu Lei

Hi! I'm Yu Lei (雷 宇), a first-year PhD student at UT Austin, advised by Prof. Yuke Zhu.

Previously, I was fortunate to collaborate with Dr. Zhengyi Luo, Prof. Kris Kitani at Carnegie Mellon University, and Prof. Zhuowen Tu at UC San Diego. I obtained B.Eng. in Electrical Engineering from Shanghai Jiao Tong University, where I worked with Prof. Bingbing Ni and Prof. Zhijie Deng.

My research interests span robot learning, generative modelling, and representation learning.
I am also broadly interested in cognitive and neuroscience.
Feel free to drop me an email if you want to collaborate or just chat!
