Yingying Sun

I am a Research Associate in the Integrable Systems Group headed by Prof Nalini Joshi at the University of Sydney. Currently I am interested in integrable systems and Painlevé equations.

In 2017 I completed my PhD in Applied Mathematics under the supervision of Professor Da-jun Zhang at Shanghai University, P.R. China. In my thesis I mainly studied the applications of the theory of elliptic functions and elliptic curves in integrable systems. During my PhD I spent one year (2016-2017) at the University of Sydney studying discrete integrable systems, supervised by Professor Nalini Joshi, and supported by the China Scholarship Council.

Recently, I have been working on discrete integrable systems, which involves studying some special functions, and understanding the relations between different classes of integrable systems.
