PNNL

Laurentiu Dan Marinovici joined Pacific Northwest National Laboratory in August 2011 as a postdoctoral research associate. Before joining PNNL, Dr. Marinovici had an extensive experience as a teaching assistant while pursuing his master and Ph.D. degrees at both “Gh. Asachi” Technical University of Iasi, Romania and Louisiana State University in Baton Rouge, Louisiana. He guided students in getting knowledge about fundamentals of circuits theory and control system design. He conducted hands-on lab sessions for undergraduate students’ projects regarding classic and modern control of inverted pendulum and magnetic levitator. Dr. Marinovici is currently involved in projects related to power system stability and control using modern control theory and algorithms.
