Dr Karen Stephan is a Senior Research Fellow at the Monash University Accident Research Centre. She has over 20 years of research experience and has qualifications and skills in a number of disciplines: psychology, human factors, public health, epidemiology and biostatistics. Karen has been involved in research across a range of areas in injury prevention, predominantly in road safety. She has extensive experience with conducting research using a variety of methods, from controlled experiments designed to understand behaviour (e.g. using the driving simulator), to on-road field trials of technology, to large-scale evaluations of treatments and policy changes using pre-existing datasets. She has particular interest in how the design of the environment influences human behaviour and, consequently, safety. She is also interested in human perceptual abilities and the design of safe and efficient systems.
