Georgia Tech's Plasma and Dielectrics Lab recently hosted its annual PURPLE poster session on November 9, 2023. During the event, the lab spotlighted the research endeavors of its accomplished undergraduate students across various research domains.

The PURPLE program, designed to foster research, learning, and professional development among undergraduate students, serves as a platform for emerging scholars to delve into inventive ideas and contribute to impactful projects.

The Plasma and Dielectrics lab is actively involved in researching gas, liquid, and solid dielectrics for diverse applications, including aerospace systems, naval systems, super grid, and switchgear. Under the leadership of Associate Professor Lukas Graber in the School of Electrical and Computer Engineering (ECE), the lab's team includes ECE research engineers Zhiyang Jin and Alfonso Cruz Feliciano, as well as six graduate students.
