Falls Church resident Peter Fox-Penner is joining the faculty of the Questrom School of Business at Boston University, effective Friday, Jan. 1. In his new role of professor of practice, Fox-Penner will take the lead in establishing a new Institute for Sustainable Energy, focused on increasing energy research initiatives throughout Boston University.

Fox-Penner will maintain his association with Washington, D.C.-based The Brattle Group as an academic advisor, continuing his focus on network industry economics and policy.

“For 19 years, I have been privileged to work with some of the finest colleagues anyone could ever hope for, and to watch Brattle grow from a small regional firm to a leading global economic consultancy,” Fox-Penner wrote in an email to the News-Press. “As the firm celebrates its 25th year, and I assume my new roles, I look forward to staying connected.”
