This position will join the Network Modeling Group at the UW, an active interdisciplinary team of faculty, research scientists and graduate students, with ties to team members at other institutions, and close working relationships with public health departments at the local, state and national levels. Our research software is open source and designed to establish a reproducible research pathway for the larger scientific community. We publish and maintain a large number of packages on CRAN, including the statnet suite for statistical network analysis, and the EpiModel package for network modeling of epidemics and other diffusion processes. The position will be responsible for helping to maintain, improve and extend the existing software and develop new R packages when appropriate. The job requires a mix of excellent programming skills (in R and C), understanding of core statistical concepts and algorithms, solid math background (linear algegbra, multivariate calculus, probability), a well-organized and documented development process, effective communication with other developers and end users and a commitment to open source reproducible research tools.
