Cedric William's lab is involved in creating novel behavioral and cognitive protocols to train standard laboratory rodents and African Gambian rats to detect target scents associated with explosive odorants using automated methods. They design computer-automated instrumental learning techniques in training rodent species to become efficient bio-detectors of explosives odorants or a wide range of hazardous chemical agents. The objective of this work is to create proven behavioral strategies that reduce the time frame for training rodents to reliably search for, identify and distinguish explosive and other harmful odorants from a number of distractor odors.
