Gov. Brad Henry named Pettit to the job last month. Pettit is scheduled to appear at a meeting of the House Government Modernization Committee Monday — his first day on the job.
Pettit was selected following passage of legislation last year authorizing the governor to appoint a chief information officer to oversee state computer information and technology operations.
Pettit was formerly a technology consultant in Denton, Texas, and a project manager for Brown University. He is working on a doctorate in information sciences at the University of North Texas in Denton.
Pettit will be paid $160,000 a year.
