Nov. 16, 2004 – Zyomyx Inc. (News, Web) tapped its chief technology officer to take over as chief executive as it scales back its business. Peter Wagner, a founder who has led the firm’s technology efforts since 1998, succeeds Robert Monaghan as CEO. Wagner co-founded the Hayward, Calif.-based biochip developer to commercialize protein analysis tools.

The restructuring has included layoffs and an auction of production and research equipment. The company said in a news release this week that it’s focusing on development and marketing partnerships to leverage its existing technological assets and intellectual property.
