I am a postdoctoral researcher at Universität Bonn. My field of interest is algebraic geometry, especially on topics related to compact hyper-Kähler manifolds and their Lagrangian fibrations.

Sometimes I write my name as Yoonjoo Kim without a dash.

I completed my PhD degree at Stony Brook University under the guidance of Professor Radu Laza.

• Here is my dissertation: pdf.
  It summarizes some of my work on hyper-Kähler manifolds. It also provides a very brief survey on basic theory of Lagrangian fibered hyper-Kähler manifolds.
