Hak Yong Lee

Design Optimization Development Engineer, Divergent Technologies


My name is Hak Yong Lee. I have studied in Yonsei university for my bachelors and masters. While I was taking an undergraduate class, I got interested in machine/structure design and improving designs with different design methods. That interest led me to this path, and I am currently studying in Johns Hopkins.
