Fundamental identifiability limits in molecular epidemiology

This study identifies fundamental limits in phylodynamic inference, showing that epidemiological parameters cannot be uniquely determined from viral phylogenetic data alone.

Why extinction estimates from extant phylogenies are so often zero

The paper explains why extinction rate estimates from extant phylogenies often show zero, due to congruent diversification scenarios and model constraints.

A General Birth-Death-Sampling Model for Epidemiology and Macroevolution

The paper unifies various birth-death-sampling models into a general framework, showing they are special cases of a more general model and provides a method to derive likelihoods for complex scenarios.

Phylogenies of extant species are consistent with an infinite array of diversification histories

The paper shows that extant timetrees cannot uniquely determine diversification scenarios, as infinitely many scenarios can generate the same tree.

Microbial metabolite fluxes in a model marine anoxic ecosystem

The paper develops a computational method to estimate microbial metabolite fluxes in the Cariaco Basin, revealing higher diffusivity of reductants than previously thought.
