Carleen Basler, an assistant professor of American studies and sociology at Amherst College, resigned last week after senior faculty members discovered that she had plagiarized some of her scholarly work. The plagiarism was found as Basler was being evaluated for tenure, officials said. “She accepted responsibility and decided to resign,” said Gregory Call, the dean of faculty at Amherst and a mathematics professor. Biddy Martin, president of the college, said that Basler had worked at Amherst since 2003. When asked about the extent of plagiarism, Martin said it was "extensive." An automatic reply to an e-mail sent to Basler’s college e-mail account said: “Carleen Basler is no longer with Amherst College.” Basler did not reply by deadline to an e-mail sent to her private address.
