<p>Hi!! I'm Dingxi (Kristen) Zhang, a computer science Master student at ETH Zurich.
Before that, I was studying at the University of Chinese Academy of Sciences (UCAS). My research focus on 3D vision,
computer graphics and generative models.
I'm fortunate to be working with <a
href="http://geometrylearning.com/lin/">Prof. Lin
Gao</a> and <a
href="https://people.ucas.edu.cn/~sgshan?language=en">Prof.
Shiguang Shan</a> at Institute of Computing Technology, Chinese Academy of Sciences.
I'm also currently an intern at <a href="https://www.tripo3d.ai/">VAST</a>.
</p>
<p>
In my spare time, I love playing basketball, skiing, strumming the guitar, and constructing some Lego creations.
