A spatial epidemic model with a moving boundary
Infectious Disease Modelling, 2021 We present a new mathematical model to investigate the spatial spread of an infectious disease. The model consists of a nonlinear PDE system with an unknown velocity field, defined on an epidemic domain that changes with time.

Confronting Mathematical Pseudo-Community: A Domain-specific Analysis of a Middle School Mathematics Department [PDF]
EURASIA Journal of Mathematics, Science and Technology Education, 2019 Teacher professional community refers to the extent to which teachers collaborate to further their own and their students’ learning. Peck (1995) drew distinctions between pseudo-community and professional community, where pseudo-communities rely on suppression of conflict and the tacit understandings that it is “against the rules” to challenge others ...

Journal of Numerical Cognition, 2017 Many children struggle to successfully acquire early mathematics skills. Theoretical and empirical evidence has pointed to deficits in domain-specific skills (e.g., non-symbolic mathematics skills) or domain-general skills (e.g., executive functioning and language) as underlying low mathematical performance.
