First snow in Aachen, Germany

Jiao Sun

master student @ IIIS, lead by Andrew Chi-Chih Yao in Tsinghua University under the supervision of Prof. Wei Xu. I was top 1% in the computer science department when graduated and was awarded the highest award for bachelors in Shandong University. I was sixteen when I started my undergraduate.

My research interest currently lies in using human computer interaction, especially data visualization techniques to understand and assist machine learning algorithms. I am also interested using HCI in the natural language processing, social computing, crowdsourcing and education technology settings.

I want to thank all of the people who have supported me through this journey.
I was so lucky to have Professor Wei Xu as my advisor, my friend, and my idol during my master's study! His attitude toward research and family will guide me all my life. I still remember the day when we stayed all night together to revise papers. He is also the one who inspires me to do a Ph.D. My career ambition is to be a professor, and I hope my students will also love me as much as we love him! I hope one day, I will also make him proud. 😇
Dr. Ling Huang, CEO of Fintech. Inc in China gave me the unique opportunity to work with industry giants, which makes me work on real-world problems.
Thank you all as well as my family and friends. There is no way I would be who I am right now without you.
