Ellen worked in the Clemson Visual Perception and Performance Laboratory examining the factors contributing to the conspicuity of pedestrians and bicyclists in challenging road conditions, such as nighttime driving. She did her dissertation on “The Influence of Pedestrian Biological Motion on Time-To-Collision Estimates at Night”. Prior to entering the forensic field, Ellen planned and conducted experiments for a major bicycle manufacturer. She wrote and presented reports to stakeholders and product managers that improved and applied knowledge of bicycle conspicuity. She also conducted laser strike perception studies for the Department of Defense.
Ellen applies her experience in Human Factors to the analysis of crash investigations and other personal injury matters. These matters often include collisions involving vulnerable road users and drivers, driver distraction, and slips, trips, and falls. She utilizes her knowlegde of OSHA regulations, codes, and standards in her analysis of premises liability incidents and safety consulting.
