Tianyi Hao


My name is Tianyi Hao (郝天一, hǎo·tiān·yī). Welcome to my home page!

I received my Ph.D. degree on computer science from the Institute for Interdisciplinary Information Sciences (IIIS) at Tsinghua University in 2021. I was working as an intern in Big Data Lab, Baidu Research from 2015 to 2017.

Before that, I have finished my undergraduate study in Yao class at Tsinghua, and received my B.S. degree in 2014.
