Sean Hwang.
I'm a professor of chemical engineering at Inha University and the CEO of CEPiEL. I work on digital twins and AI for chemical processes — the kind that have to actually run a real plant, not just look good in a paper.
This site is where I write about that work, and post the occasional interactive demo.
Two homes
This site sits between my two day-to-day homes — the lab at Inha and the company. Pick a side; both doors are open.

Why digital twins for chemical processes are different
A digital twin of a refinery is not a digital twin of a wind turbine. The differences matter.
