Jinhwa has spent majority of her childhood in a small, isolated island called Koje Island in Korea. She moved on to Seoul to study materials science and engineering from scarcely populated island where such things were almost impossible. After finishing her M.S degree in Advanced Material and Chemical Engineering from Hanyang University, Jinhwa had worked at Samsung Electronics. She has studied the devices and processes with inorganic materials and she had developed lots of unit module processes such as isolation, plasma nitridation, and plasma oxidation processes at Samsung. Jinhwa began her doctorate study in the Materials department with Professor Craig Hawker in the fall of 2008.
Jinhwa is currently interested in the preparation of polymer-coated inorganic nanoparticles and their use in the fabrication of well controlled architectures using soft imprint lithography. These devices with well defined structures can be used in various electronic applications such as battery and semiconducting devices.
