Bio: Justin Dimmel is associate dean for academics and student engagement in the University of Maine College of Education and Human Development, where he also serves as an associate professor of mathematics education and instructional technology in the School of Learning and Teaching. Dr. Dimmel has taught both undergraduate and graduate courses in teacher education. He is the founder and director of the Immersive Mathematics in Rendered Environments (IMRE) Lab, which designs virtual and augmented reality math and science learning environments, and investigates how VR and AR technologies can transform STEM education. In addition, he led a team that developed the SunRule, an interactive sculpture that harnesses the rays of the sun to help users explore multiplication and division. The project was chosen for UMaine’s MIRTA accelerator, a program designed to advance research along the path to commercialization, turning lab innovations into real-world products and services with public benefit. In 2022, Dimmel received a National Science Foundation CAREER Award, the organization’s most prestigious award for early career faculty.
