Sheri Stickley of Edmond on Tuesday was appointed interim executive director of the Oklahoma Center for the Advancement of Science and Technology.
Her appointment was made after OCAST's board of directors accepted the resignation of William A. Sibley, who has held the position nearly five years.
In early June, Sibley was charged in Oklahoma County District Court with 22 felony counts of making false claims against the state.
Sibley, 71, was indicted by a multicounty grand jury for allegedly approving false time sheets submitted by former OCAST employee Geneva Faye Worthen. The indictments naming Sibley were unsealed before Judge Vicki Robertson.
Worthen, 56, was indicted by the grand jury in April for submitting claims totaling more than $28,000 for 885.5 hours of work she allegedly did not perform.
According to the indictments unsealed June 1, Sibley was Worthen's direct supervisor and knowingly, willfully and feloniously approved her bogus time sheets. Each charge carries a penalty of up to two years in prison and a fine of up to $10,000.
Sibley entered a plea of not guilty. A preliminary hearing conference is scheduled for 1:30 p.m. on July 22 before Judge Fred Doak.

Stickley most recently served as director, technology development programs division at OCAST. …
