The Cauchy Process on Phylogenies: a Tractable Model for Pulsed Evolution

This paper introduces the Cauchy Process as a tractable model for pulsed evolution on phylogenies, showing it can accurately reconstruct ancestral traits and capture complex evolutionary patterns.

Distributions of extinction times from fossil ages and tree topologies: the example of mid-Permian synapsid extinctions

The paper presents a method to estimate extinction times using phylogenetic trees and fossil data, showing improved accuracy for mid-Permian synapsid extinctions.

Exact distribution of divergence times from fossil ages and tree topologies

The paper computes the exact probability distribution of divergence times using fossil ages and tree topologies under the Fossilized-Birth-Death model, finding an older age for the Amniota divergence than previously assumed.

Probabilities of tree topologies with temporal constraints and diversification shifts

This paper develops a method to compute probabilities of undated phylogenetic trees with temporal constraints and diversification shifts, demonstrating its applications through three examples.

Testing for correlation between traits under directional evolution

The paper introduces a method to test for correlation between traits under directional evolution by correcting bias through multiple regression, outperforming existing methods in simulations and applied to hominin data.

Time-dependent-asymmetric-linear-parsimonious ancestral state reconstruction

This paper introduces a time-dependent asymmetric linear parsimony method for ancestral state reconstruction and demonstrates its application to cetacean body size evolution.

Detecting Molecular Basis Of Phenotypic Convergence

The paper develops a method to detect molecular basis of phenotypic convergence by improving site-level measures and applying them to echolocation convergence in dolphins and bats.
