The political, social, and institutional environments in which contemporary universities operate have changed rather dramatically over the past two decades in ways that threaten the resilience of the academic core, both in its ability to map knowledge comprehensively and also to maintain a balance between the branches of the humanities, social sciences, and natural sciences. This paper traces historical changes (2003-2019) in the academic core of two "flagship" research-intensive universities located in Northern Europe. The results show that some branches of the academic core are undergoing dynamic processes of program churn that make them resilient. Furthermore, the data show that this resilience is enabled in large part by bridging different branches of knowledge by establishing what we term interbranch programs. In addition to the abovementioned findings, the paper links ongoing discussions regarding change in HE systems and institutions to the literature on organizational resilience, and it advances insights for a possible future theory of how adaptation plays out in the academic core over time.
