Laurie Dyke, a financial investigator in Marietta, will become the newest member of a citizens oversight panel in Cobb County.

Dyke, who was appointed by Commissioner JoAnn Birrell, replaces Chuck Casto, a deputy regional administrator with the Nuclear Regulatory Commission who is leading the United State’s assistance efforts in Japan.

The oversight committee is tasked with reviewing Cobb’s management structure and to provide recommendations on solutions for the 2012 and 2013 budgets. The committee’s recommendations are due to county commission on June 28.
