Projects

Here are some of our current projects - mostly focusing on simulating genomic data, and Galapagos taxa.

Homoploid hybrid speciation
Homoploid hybrid speciation Argyranthemum from the Canary Islands

Using Pangenome and Ancestral Recombination Graph approaches to study how Argyranthemum evolved its two hybrid species.

Dating colonization of Tribulus
Dating colonization of Tribulus Are adaptive radiations predictable?

We are using Ancestral Recombination Graph approaches to determine the colonization of Tribulus. How long have the finches favourite species been on the islands?

Parallel evolution in Cabo Verde Diplotaxis
Parallel evolution in Cabo Verde Diplotaxis Cabo verde Diplotaxis

We are combining fieldwork, pangenome and ARG approaches to understand the repeated/parallel evolution of Diplotaxis to different climatic niches.

IslandParadox
IslandParadox Unraveling the Paradox of Genetic Diversity in Isolated Oceanic Lineages

We are exploring the adaptive radiation of Scalesia! Soon to expand to other projects.

Niche conservatism in adaptive radiation?
Niche conservatism in adaptive radiation? Are adaptive radiations predictable?

We are using mathematical modelling to understand how niche conservatism affects an adaptive radiation!

The tempo of hybridization
The tempo of hybridization Despeciation or diversification?

How does the tempo of hybridization affect the rates of despeciation or diversification?

Can we trust hybridization tests?
Can we trust hybridization tests? Simulation of ABBA-BABA and f4 statistics

How does the demographic history, number of samples and SNPs affect common hybridization tests?

Genetic load in an insular Heliconius
Genetic load in an insular Heliconius Does a putative hybrid species carry genetic load?

In collaboration with Camilo Salazar and others in U de Rosario we are analysing genetic load in an insular Heliconius species

GWAS your way through
GWAS your way through How many samples do we need for a GWAS?

We are simulating trait and genomic data to understand the number of samples required for a GWAS approach.
