During his career in academe, he founded the modern high-energy physics group at the University of Nebraska-Lincoln. He was promoted to full professor in 2008. He also helped establish the Cosmic Ray Observatory Project in Nebraska high schools and was a leader of education, outreach, and public relations for the Pierre Auger Project in Argentina. Greg made a significant contribution to the field of particle physics. He was a contributing member of collaborations that made key discoveries, including the search for the Higgs boson particle. The discovery led to theorists being awarded the 2013 Nobel Prize.
