The research which Ondetti worked on was also improved. Instead of sending samples to the United States from Argentina, he brought them down the hall. Ondetti was placed in the peptide synthesis research group. As opposed to his initial reaction to carbohydrate chemistry, he was pleased because he enjoyed contact with biologists. Over the next nine years, Ondetti gained recognition in peptide synthesis and the position as peptide chemistry chair. After this promotion, Miguel and his wife, Josephine, definitely decided to stay in America after considering the possibility of moving back during the original move.
