The spring 2015 semester has started at UNIST!
This semester, Prof. Katherine A. Kim is teaching a newly-established graduate course on power systems (based on the previous Special Topics course).
ECE560: Power Systems [전력시스템]
Level: Masters Course
Description: Power Systems is a graduate level course where you will learn the basics of the electric power grid and present-day research challenges in power systems. The primary goal of the course is for students to gain a clear understanding of how the power grid and power systems functions and to be able to communicate that understanding to their peers.
Also, two new M.S. students have joined the PEARS Lab:
