Short Bio

Ruohan Gao is a Ph.D. student under the supervision of Prof. Kristen Grauman in the Department of Computer Science at The University of Texas at Austin. Ruohan's research interests are in computer vision, machine learning and data mining. Particularly, he is currently interesed in unsupervised learning from unlabeled images and videos.

Ruohan received his B.Eng. degree from the Department of Information Engineering at The Chinese University of Hong Kong (CUHK) in 2015 with First Class Honours. At CUHK, Ruohan conducted research on large graph mining through graph sampling under the supervision of Prof. Wing Cheong Lau.


  • [March, 2016] I started to work on computer vision and joined UT-Austin Computer Vision Group. I am luckily advised by Prof. Kristen Grauman.
  • [July, 2015] I graduated from CUHK with First Class Honours and I am going to UT Austin this fall to pursue my Ph.D. degree in Computer Science. I look forward to the challenges and opportunities that await.
