Sandra Marshall

Dr. Sandra Marshall is the Chief Science Officer at EyeTracking LLC. She founded EyeTracking, Inc. (ETI) in 1999 and served as CEO and CSO until ETI became EyeTracking LLC in 2019.

For over three decades, Dr. Marshall has carried out groundbreaking research that examines patterns of individuals’ eye movements and changes in pupil size over extended periods of time. In so doing, she developed and patented several new measures of cognitive activity and engagement. She continues her research efforts today—often in collaborative work with EyeTracking clients who are implementing these measures in applied, real-world settings.

Dr. Marshall also was Professor of Psychology at San Diego State University for more than 20 years, during which time she taught graduate statistics and managed more than 25 government research projects, primarily under DoD support.
