Dr. Ignacio Chapela, whose research revealed contamination of native Mexican corn with genetically engineered DNA, taught his last class at University of California, Berkeley. Chapela was denied tenure at Berkeley, despite "overwhelming support from his own department and from his academic peers," GM Watch founder Jonathan Matthews writes. Chapela had also been a critic of a $25 million research deal between UC Berkeley and the Swiss biotechnology company Novartis (now Syngenta).
