The primary desired skill is ability to run computational simulations, and to collect and analyze data from them. The available funding would pay for four semesters of full-ride Masters tuition, plus 15-20 hours/week of a work-study job during the academic year. The American University Game Lab offers three Masters-level degrees: the MS in Computer Science's Game & Computational Media track, the MA in Game Design, and the MFA in Games and Interactive Media.
The successful applicant would be funded on the National Science Foundation grant Characterizing Algorithm-Relative Difficulty of Agent Benchmarks. This does not have any citizenship/nationality requirements.
Anyone interested should both apply for the desired Masters program through the official application linked above (deadline July 1, though earlier is better), and email me to indicate that they would like to be considered for this scholarship. It's also fine to email me with inquiries before applying.
