Cognitive and Information Sciences (CIS) is flourishing at UC Merced, and worldwide as an interdisciplinary growth area for science and engineering.  We propose to build on our track record of excellence in research and education.  We plan to maintain the steady pace of growth in CIS that has built our cohesive unit, while also fostering numerous connections to other groups on campus and within the UC system.  We also outline how these connections could be expanded through an initiative in computation and data science, with an emphasis on human activity in its many forms, across many scales, and in its many environments.  In this document, we provide rationale in the context of campus-wide goals and national trends, and outline plans and resource needs for realizing this vision.
