Calabasas-based network testing equipment and software developer Ixia said late Thursday that the firm's CEO, Vic Alston, has resigned, after the company's audit committee determined that Alston had mis-stated his academic credentials. According to Ixia, Alston had incorrectly claimed to have received a B.S. and a M.S. in Computer Science from Stanford, and had misstated his age and early employment history. Ixia said it has named founder Errol Ginsberg as acting CEO, and appointed Alex Pepe, the company's Senior Vice President, Strategy, as Chief Operating Officer. Alston had been at Ixia for the last nine years. Alston is not the first CEO to lose his position over a fabricated resume; Internet giant Yahoo faced a similar executive turnover last year, deposing new CEO Scott Thompson, after Yahoo uncovered a similar resume issue.
