Jackson specializes in the study of human-plant coevolution and anthropological genetics, especially African human genetics and population biological substructures in peoples of African descent. For example, genetic changes in human evolution due to cultural migrations. A significant portion of her research is dedicated to examining the properties of cassava, a starchy root similar to a potato. Jackson's studies reveal that individuals in Liberia, West Africa, who consume considerable quantities of cassava exhibit immunity against certain illnesses. Notably, they display reduced rates of
sickle cell anemia and a decreased susceptibility to
malaria compared to those with lower cassava consumption. Jackson is the Director and Curator of the Cobb Research Laboratory at Howard University where she conducts studies on African-American biological history with access to the largest collection of African-American skeletal and dental remains in the world. ==Honors and awards==
