Tianqi WANG

I am a Gibbs Assistant Professor at Yale University since 2024 fall.

I obtained my PhD in mathematics at National University of Singapore. I was also co-trained by École Normale Supérieure - PSL during my PhD. My advisors were Tengren Zhang and Nicolas Tholozan. I was previously an undergraduate at Tsinghua University and a master student at Sorbonne Université. I am interested in geometric group theory and higher Teichmüller theory.
