Nadine Weidman is a senior research associate at the Council for Responsible Genetics, a nonprofit organization that monitors recent developments in biotechnology. Her research focuses on the histories of biology, psychology, and anthropology in twentieth-century America, and particularly on the ways that these sciences envision (and fight over) the concept of human nature. She is writing a book about the scientific claim that human beings possess an instinct for aggression, a claim made popular and hotly debated in the 1960s and 1970s. Her other interests include gender in science, science popularization, and the ethical questions raised by biotechnology. She is the author of Constructing Scientific Psychology, a biography of the American psychologist and brain researcher Karl Lashley, and the co-author of Race, Racism, and Science, a history of the idea of race in science from the eighteenth century to the present. In 2001, she received the Petra T. Shattuck Excellence in Teaching Award.
