We are computational chemistry lab at POSTECH Chemistry.

We use molecular simulations to solve problems that are critical in energy/bio applications. We use/develop statistical mechanics / molecular dynamics / coarse-grained methods / machine-learning / big data analysis to understand the mechanisms of chemical processes and help designing new functional materials.

We welcome motivated grad/undergrad/postdocs who loves coding / physical thinking / finding and solving new problems that are relevant to energy / biological applications. Interested should email me to changyunson@postech.ac.kr.

More details of my research interest can be found in the Research section.
