As a boy, JesÚs Pineda traveled each summer from his home in Mexico City to his grandmother’s ranch in central Mexico, where he fished for catfish from a local river. That interest spurred a biology and oceanography career, and he quickly found barnacles, sea anemones, clams, and other creatures without backbones more intriguing than fish. After earning degrees in biological oceanography and marine ecology at Escuela Superior de Ciencias Marinas and at Centro de InvestigatiÓn Cientifica y de EducaciÓn Superior de Ensenada in Mexico, he completed doctoral studies in oceanography at the Scripps Institution of Oceanography. He joined WHOI as a postdoctoral scholar before becoming an associate scientist in 1998. For his research, he has explored coastlines in the United States, as well as Mexico, Chile, and Panama.
