Shixiang (Shane) Gu, 顾世翔

I started PhD in Machine Learning under Cambridge-Tübingen PhD Fellowship in the fall 2014, where I am co-supervised by Richard E. Turner and Zoubin Ghahramani at University of Cambridge, and Bernhard Schölkopf at the Max Planck Institute for Intelligent Systems in Tübingen. I also collaborate closely with Sergey Levine at UC Berkeley/Google Brain and Timothy Lillicrap at DeepMind. I completed my B.ASc. in Engineering Science from the University of Toronto, where I did my thesis with Prof. Geoffrey Hinton in distributed training of neural networks using evolutionary algorithms. I also had a great fortune and fun time working with Prof. Steve Mann, developing real-time HDR capture for wearable cameras/displays. I previously interned at Google Brain hosted by Ilya Sutskever and Vincent Vanhoucke. My PhD is also funded by NSERC and Google Focused Research Award. I am a member of Jesus College, Cambridge.

I am a Lab Scientist at Creative Destruction Lab, one of the leading tech-startup incubators in Canada.

My expected graduation date is June-August, 2018.
