**Zicong Fan (Alex)** ![ ](./assets/zfan.jpg width="50%") I am a doctoral student at ETH supervised by Professor [Otmar Hilliges](https://ait.ethz.ch/people/hilliges/) and MPI Director [Michael J. Black](https://ps.is.mpg.de/~black). My main research interests lie in computer vision and machine learning. These include topics such as hand pose estimation and modelling the interaction of human-objects and human-scene. I am also interested in egocentric computer vision. Before starting my Ph.D., I finished my B.Sc. (2018) and M.Sc. (2020) in Computer Science at The University of British Columbia, Vancouver, Canada. In my bachelor, I worked with Professor [Ian M. Mitchell](https://www.cs.ubc.ca/~mitchell/) in robotics. In my Masters, I worked in vision + language problems with Professor [Leonid Sigal](https://www.cs.ubc.ca/~lsigal/) and Professor [Jim Little](https://www.cs.ubc.ca/~little/).
