Welcome to Kyung-Han Choi's webpage

Hello, I am a postdoctoral research fellow under the supervision of Dr. Hao Wang and Dr. Thomas Hillen at ILMEE(Interdisciplinary Lab for Mathematical Ecology & Epidemiology) in University of Alberta.

My research interest primarily lies in biological diffusion on the heterogeneous environment. I received my PhD degree from the Department of Mathematical Sciences at KAIST, where I studied under the guidance of Dr. Yong Jung Kim.

Here is my CV.

Research Interest

I am mainly interested in the heterogeneous diffusion and its applications to various areas.

- Chemotaxis models
- Nonlocal population models based on heterogeneous cognitive map
- Traveling wave solutions of nonlinear diffusion models
- Epidemic models and dispersal strategies
