Spring 2015 Update

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:

Hyunji Lee (이현지) – M.S.

Hyunji Lee received the B.S. and M.S. degrees in electrical engineering from the Ulsan National Institute of Science and Technology, Ulsan, South Korea, in 2015 and 2017, respectively. She is working as an Assistant Engineer with Fine Inc., Seoul, South Korea. Her research interests include design and analysis of differential power processing systems for photovoltaic applications.

Fall 2014 Update

Katherine A. Kim (김예린) has officially started as an Assistant Professor in the School of Electrical and Computer Engineering at Ulsan National Institute of Science and Technology (UNIST). In Fall 2014, she will be starting up her research lab and teaching the following courses:

EE313: Introduction to Control [자동제어공학개론]
Level: Undergraduate 3rd-year course
Description: This course introduces fundamentals of linear systems control: mathematical modeling, analysis, and design of systems, transfer function, root locus, bode diagram, Nyquist method, and state space method.

ECE637: Special Topics: Power Systems [전자회로설계및응용특수토픽III]
Level: Masters Course
Description: This special topic course on Power Systems is a graduate level course where you will learn the basics of the electric power grid and the challenges of moving towards a more intelligent grid.
