Cal's search for a new athletic director could take almost a year, said Chancellor Nicholas Dirks, who will rely on significant input from the interim director he appointed two weeks ago.

In his first public comments since announcing June 27 that Sandy Barbour was out after a decade on the job, Dirks on Wednesday provided more details on his expected timeline and the process that will determine the next athletic director.

Cal alum Michael Williams will begin his assignment as interim A.D. on Tuesday, and is charged with running the department while providing Dirks with regular feedback on what he sees as priorities going forward.

Dirks said nothing tangible, including the hiring of a search firm or the assembling of a search committee, will begin until the Chancellor's Task Force on Academics and Athletics provides its recommendations. That report originally was scheduled to be delivered by late June, but now is expected in September. Dirks created that panel last fall to generate a plan to improve the academic standing of Cal's sports teams.

Because most candidates will be employed at other schools, Dirks said he doesn't expect to complete the process sooner than February or March, possibly not until June.

"We're going to pause for a minute. We don't have to rush," said Dirks.

Williams, retired from his career as an investment banker, has agreed to stay on for up to a year. He is being paid a salary, Dirks said, but will fold that into his philanthropic giving to his alma mater, meaning he is essentially a volunteer.

Dirks reiterated that Williams does not want to be a candidate for the permanent position.
