Garrett Johnson

Associate Professor, Marketing

Prof. Johnson researches digital marketing: measuring its effectiveness and examining its privacy issues. His ad effectiveness research uses large-scale experiments to measure how and how much ads work. His privacy research both examines the impact of Europe’s GDPR and studies the economics of identity in online advertising.

For his work, Prof. Johnson has been awarded the Paul Green Award, the Weitz-Winer-O’Dell Award, and the John D. C. Little Award, and has been a finalist for the John D. C. Little Award and Gary Lilien Marketing Science Practice Prize. For current and complete information on research, visit garjoh.com.
