Quidel said this week that John Radak will be stepping down from his role as CFO, and that Randy Steward will be taking his place effective Oct. 31.
Steward previously served as CFO for medical device company Navilyst. He has also served as COO for SeQual Technologies in San Diego, and executive vice president and CFO at Spectrum Brands.
Bernd Brust has resigned as president of molecular medicine at Life Technologies to pursue other opportunities, the company said in a filing with the US Securities and Exchange Commission this week.
Brust has led the molecular medicine business unit since January, when it was created to help the company transition next-gen sequencing into the clinic. He previously served as Life Tech's president of commercial operations.
Life Tech said that Brust will continue to serve as a consultant through Dec. 31 "to assist the company with various endeavors."
