Gregoire has worked in the field of road and rail safety since 2007. In this time, his research is at the intersection of engineering, mathematics and human factors to improve the safety of road users. His main areas of expertise and interest include the modelling of driver behaviour in driving simulators and on roads, particularly when impaired. He has successfully led numerous research projects, particularly for the transport government and the rail industry.
Gregoire’s current research is focused on the development of new technology using Artificial Intelligence to automatically detect impaired driving. His current projects seek to understand the effects of alcohol or medicinal cannabis on driving performance in a driving simulator. These projects are stepping stones toward the automatic detection of alcohol and cannabis impairment using in-vehicle or roadside technology.
