About

    Kyung Won (K-Won) Chang


"I am with you and will watch over you wherever you go, and I will bring you back to this land. I will not leave you until I have done what I have promised you (Genesis 28:15)."


Kyung Won (K-Won) aims to understand the dynamics of multiphase flow and solute transport in deformable geological porous media. He started his academic career with engineering minds, a B.Sc. in geotechnical engineering and a M.S. in petroleum engineering. He achieved his Ph.D. in geological sciences. Kyung Won believes that his multidiscipline background will allow him be a smart bridge between geo-engineers and geo-scientists.
