Xuan Nguyen (Hampton City Schools) and Matthew Carter (Gloucester County Public Schools) were invited to speak recently before the Association of Energy Engineers (AEE) at their monthly meeting in Williamsburg.  As part of Senior mentorship experience, and sponsored by the Center for Entrepreneurial Innovation at Old Dominion University, Xuan and Matt have been performing research forecasting the trajectories of advanced energy efficiency technologies aboard ships for a local company.  Researchers with the company who were members of the AEE found the results so intriguing and compelling, they asked the students to present their work at their monthly meeting.  The students were guided in their research by their teacher-mentor, Steven R. Walk, whose research career has included the use of quantitative methods to model the growth and diffusion of technology and technological change.
