In his teaching, Greg Gangi conveys a complex understanding of environmental challenges and explores innovative solutions. His teaching extends beyond the classroom as he leads students to many countries to learn firsthand about global change and innovation. He organized several educational trips to Germany, the Netherlands and the Nordic nations. Given the role that South Korea and China play in shaping the future of technology, he plans to guide students in learning from these two nations during the summer of 2019.

Gangi received various awards at UNC and a national award for his advising and mentoring of students. In 2014, he was awarded the NACADA Award for Outstanding Faculty Advisor. He received the Tanner Award for Teaching Excellence in 2010 and the University recognized him with the Massey Award for Outstanding Service in 2018.

In addition to his teaching, Gangi works to create networks in North Carolina between industry, academia, and government to help strengthen innovation. He also seeks to foster international networks that connect companies in the Clean Tech sector with North Carolina. He defines clean technology broadly to include companies in clean energy, smart cities, water technologies, innovations to make transportation more sustainable, building technologies and solutions that improve food security and agricultural sustainability. He is the lead organizer of the annual UNC Clean Tech Summit, which represents the largest event of its kind in the southeastern region of the United States.
