Abigail Marsh is an associate professor of psychology, neuroscience, and cognitive science at Georgetown University. She received her PhD from Harvard University and conducted her post-doctoral research at the National Institute of Mental Health. Her research is aimed at answering the questions: How do we understand what others think and feel? What drives us to help other people? What prevents us from harming them? She addresses these questions using functional and structural brain imaging in adolescents and adults, as well as behavioral, cognitive, genetic, and pharmacological techniques. Her work has been funded by the NIH, NSF, and John Templeton Foundation and includes over 70 publications, including her award-winning book The Fear Factor (2017, Hachette) about her research on the neuroscience of empathy, altruism, and aggression. She has also written for popular media outlets including NPR and The Washington Post.
