    Alere Inc. disclosed earlier in the week that the Waltham medical diagnostic products company had named chief operating officer Namal Nawana interim CEO and president following the resignation of Ron Zwanziger.
    Jerry McAleer, senior vice president of R&D and a company director, and Dave Scott, chief scientific officer, have also resigned, Alere said. The company said its board will now start a search for a permanent chief executive.
