For the last 30 years Dr. Mora's research has focused on documenting the impacts of persistent organic pollutants, agricultural pesticides, metals, and other contaminants of emergent concern on avian species. Dr. Mora's work has focused on the southwestern United States, along the U.S.-Mexico border, and in various other regions of Texas, California, and Arizona. In the southwestern U.S., Dr. Mora investigated the accumulation and impacts of environmental contaminants in raptors, particularly aplomado falcons (Falco femoralis) and peregrine falcons (Falco peregrinus), and various other endangered species of the U.S.-Mexico border. He has also conducted various research projects in Mexico.
