BACKGROUND

Kathryn Johnson received the B.S. degree in electrical engineering from Clarkson University in 2000, and the M.S. and Ph.D. degrees in electrical engineering from the University of Colorado in 2002 and 2004, respectively. In 2005, she completed a postdoctoral research assignment studying adaptive control of variable-speed wind turbines at the National Renewable Energy Laboratory's National Wind Technology Center. In October 2005, she was appointed Clare Boothe Luce Asst. Prof. at the Colorado School of Mines in the Division of Engineering. Her research interests are in control systems and control applications, specifically wind energy. Her funded research projects have included modeling and control of a small wind turbine with a continuously-variable transmission and increasing the energy capture of a wind farm using coordinated turbine control.

RESEARCH AREAS

Control of wind energy systems, control systems applications, engineering education.
