Cell-to-cell information at a feedback-induced bifurcation point
Amir Erez, Tommy A. Byrd, Michael Vennettilli +1
A ubiquitous way that cells share information is by exchanging molecules. Yet, the fundamental ways that this information exchange is influenced by intracellular dynamics remain un…

Biochemical feedback and its application to immune cells II: dynamics and critical slowing down
Tommy A. Byrd, Amir Erez, Robert M. Vogel +4
Near a bifurcation point, the response time of a system is expected to diverge due to the phenomenon of critical slowing down. We investigate critical slowing down in well-mixed st…

Nutrient levels and trade-offs control diversity in a serial dilution ecosystem
Amir Erez, Jaime G. Lopez, Benjamin Weiner +2
Microbial communities feature an immense diversity of species and this diversity is linked with outcomes ranging from ecosystem stability to medical prognoses. Yet the mechanisms u…
