Research Interests
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.
My work primarily focused on diverse mollusc groups, but I also explore the wider realm of marine invertebrates to address my research questions (I 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 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.
I welcome new students who are passionate about invertebrate evolutionary genomics! Contact me: sarah.lemer@gmail.com
I am part of the NSF funded Guam Ecosystems Collaboratorium. Learn more about what we do here: Guam EPSCoR
Current Projects
Bleaching Resistance
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.
Bivalve Phylogenomics
Phylogenetic relationships among bivalves still show areas of uncertainty, especially within the Imparidentia group. We sequenced and are analyzing over 100 transcriptomes of bivalves to shed light on the phylogeny of this diverse group of molluscs.
Coral Population Genomics
We are exploring the genetic connectivity, diversity and structure of multiple coral species around the island of Guam using a RAD-Seq approach.
Micronesian Reef Fish Phylogeography
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.
