The Island Evolution Lab at the UOG Marine Lab is a group of researchers and students interested in basic and applied evolutionary question in island settings. We are using genetic and genomic approaches (RAD-Seq, RNA-Seq and Genome sequencing) in combination with field work, observations, collections, museums, specimens and experimental manipulations to address original questions in population genetics, phylogenetics, phylogeography, molecular ecology and genomics.
The Island Evolution Lab is partially funded by the NSF EPSCoR Guam Ecosystems Collaboratorium.
We are always looking for graduate and undergraduate students who are interested and passionate about evolution, genomics and population genetics!

Karim received his Bachelor’s degree in Marine and Atmospheric Science at the University of Miami, majoring in Marine Science and Biology and minoring in chemistry. He is currently studying the population genetic structure of the scleractinian coral Porites lutea around Guam. His major research interests include population genetics and invertebrate zoology.

We are exploring the genetic connectivity, diversity and structure of multiple coral species around Guam and throughout Micronesia using an in-house RAD-Seq approach.
This is a major focus of our lab and both Dareon and Karim MS thesis are focussing on coral population genomics for their thesis research (see team).
The main phylogenetic relationships among corals have been highly controversial for years. Recently genome-sclae datasets have started to clarify many of these important relationships. We are currently assembling on one of the largest genomic dataset to study the deep relationships in the coral tree of life.
We are using experiments to induce coral bleaching in aquaria experiment to characterize the molecular processes that allow corals to survive and adapt to stressful environmental conditions. Most of these projects are conducted in collaboration with the Lemer Lab.
The Nautilus is one of the most iconic marine invertebrates and an important model system for evolutionary biologist and paleontologists, among others. We are using genomic tools to analyze the evolution and phylogeography of Nautilus across the species distribution range.
Coral reporudciton is of major interest, not only to improve our understanding of the basic biology of reef corals but also for their management and restoration. We are studying the reproductive characteristics of several coral species, using aquarium experiments and genetic tools.
