Peter Tseronis, the Department of Energy’s CTO and associate CIO for technology and innovation, is leaving his post at the end of October.
Tseronis has been a federal employee for more than 24 years across three departments, including most recently as the Energy Department’s chief technology officer, DOE said in a statement to FCW.
Tseronis announced his plans to leave late last week, but didn’t say where he was going next. “Effective November 1, 2015, I will begin a new chapter in my professional life as a member of the private sector,” he wrote in a LinkedIn notice.
Tseronis is a three-time Federal 100 honoree, winning in 2008, 2011 and 2012.
