hi, Bruce,
thank you for your feedback, it seems he has published many papers in Economics, however, we haven't covered Economic yet, so most of the Economic papers don't contribute to the "research area" calculation, and only his work
published in "ELearn" greatly influenced the result, which is Computer Education.
such problem will go away as we cover more domains, we're in the process of doing so.
thanks.
