Sian Leah Beilock is exploring the science behind why people “choke” in pressure-packed situations. Specifically, she examines factors in the brain and body that influence performance, in stressful situations ranging from test taking, to public speaking, to sporting events. Using a variety of research methods, including assessing test performance to neuroimaging techniques, Sian’s work is aimed at better understanding how our cognition and reasoning skills change when we are under stress. Sian’s research is routinely covered in the media, including CNN, NPR, The New York Times, and The Wall Street Journal. In 2017, the National Academy of Sciences honored Sian with the Troland Award, in recognition of her pioneering work in experimental psychology. Sian has published two books and over 100 papers though her research. After serving as Executive Vice Provost of the University of Chicago, Sian was recently appointed as the eighth President of Barnard College.
