Research in the Lemer lab focuses on understanding how biodiversity arises and is maintained in marine invertebrates, at the species, population and individual levels, in the context of a changing environment.
Our work primarily focused on diverse mollusc groups, but we also explore the wider realm of marine invertebrates to address our research questions (We even sometimes venture into the vertebrate world!).
In the Lemer lab we mainly use a combination of field work, experiments in controlled environments, Next Generation Sequencing approaches (RNA-Seq, RAD-Seq, Tag-Seq and Genome sequencing) and bioinformatics to answer questions about population genetics, phylogeny and gene expression in various taxa such as Annelids, Bivalves, Cephalopods and Scleractinian corals.
The Lemer Lab stands for justice and equal treatment of people regardless of race, origin, gender or sexual orientation. As such we promote inclusive, anti-racist, anti-sexist and anti-discriminatory practices. The PI is committed to actively work towards advancing women, people of color and pacific islanders in the lab and the classroom with opportunities such as science education, lab experience, conference attendance and outreach. We welcome new students and postdocs who share our values and are passionate about invertebrate evolutionary genomics, contact me: firstname.lastname@example.org

We are using in aquaria experiments to reproduce the extreme environmental conditions that lead to coral bleaching. The goal is to identify and characterize the molecular processes that allow some corals to adapt to and survive extreme environmental conditions when others usually bleach and/or die.
Phylogenetic relationships among bivalves still show areas of uncertainty, especially within the Imparidentia group. We sequence and analyze bivalve transcriptomes and genomes to shed light on the phylogeny of this diverse group of molluscs.
Species and population resilience to changing environmental conditions depend on genetic diversity and connectivity. Generally, genetic diversity and connectivity of reef-building and reef-associated taxa (e.g., corals, crustaceans, algae, mollusks) remain poorly understood in the western Pacific, an issue we will address. Being the arguably most diverse reef ecosystem within US jurisdiction, Guam and the CNMI represent a unique opportunity to study reef connectivity and resilience in a changing climate. Recovery of benthic communities following disturbance relies on connectivity but is also dependent on ecological processes like the recruitment of larvae from nearby populations. We are exploring the genetic connectivity, diversity and structure of multiple coral species in the Micronesia using a RAD-Seq or Shallow Whole Genome Sequencing approaches.
Studied species: Trapezia crabs, Tridacna clams, Drupella snails, COTs, Acropora surculosa, Leptastrea purpurea, etc...
In Micronesia, the fishing industry is a local source for food and economic development, yet movement of fish between Micronesian islands remains unknown. We hope to better understand genetic structure and diversity patterns of the fish families Acanthuridae, Lutjanidae, Scaridae and Lethrinidae across islands.

BI546 is a 4-credit graduate level course that will introduce you to the major (and not-so-major) marine invertebrate phyla. Lectures will address topics of higher-level phylogeny, anatomical and morphological diversity, life history, ecology, anatomy and physiology of each group. Laboratories will provide hands-on experience with representatives of the groups we cover in lecture. We will go to field sites as well, so that you can get experience identifying invertebrates in the field. The class will meet for two lectures per week on Tuesdays and Thursdays 2:00-3:20 PM and one laboratory on Friday 1:00-3:50 PM.
BI691 is a 1-credit graduate level course that will introduce you to the ecological and historical processes that affect distributions of organisms. The following topics are adressed through scientific paper presentation and discussion: plate tectonics and earth history, vicariance and dispersal, endemism, conservation biogepgraphy, latitudinal gradients in species richness, and the theory of island biogeography.
