Leanne Hirshfield is an Associate Research Professor and Co-Principal Investigator for iSAT. Dr. Hirshfield’s research explores the use of non-invasive brain measurement to passively classify users’ social, cognitive, and affective states in order to enhance usability testing and adaptive system design. In addition to her work at iSAT, she works with functional near-infrared spectroscopy (fNIRS), a relatively new non-invasive brain imaging device that is safe, portable, robust to noise, which can be implemented wirelessly; making it ideal for research in human-computer interaction.She received her Ph.D.in Computer Science from Tufts University in 2009, having completed her undergraduate and M.S. degrees in Computer Science at Hamilton College and the Colorado School of Mines, respectively.
