Raj Ratwani is an affiliate faculty member and a senior research scientist at Perceptronics Solutions Inc. After receiving his Ph.D. in 2008, he was a National Academies post-doctoral fellow at the Naval Research Laboratory before joining Perceptronics. His research work has focused on applying low-level theories of cognition and perception to complex applied problems with the goal of understanding how cognition unfolds under these circumstances. This approach allows for the development of stronger theories as well as for the development of technologies that facilitate cognition. His primary research areas are in human error, task interruption and resumption, supervisory control, and the cognition of complex graphs and visualizations. He is currently working towards developing eye-movement based real-time technology to facilitate human performance which can be applied in several different domains (e.g. error prediction and prevention, operator situation awareness).
