Research Interest:
The Shedlock Lab promotes integration of field biology with experimental advances in molecular medicine and genomics to test hypotheses about organismal genotype-phenotype relationships and to address complex applied problems in the environmental sciences.   Recent areas of research include: 1) the evolutionary dynamics of mobile DNA and its role in shaping eukaryotic genome architecture; 2) the use of interspersed genomic repeats as powerful biomarkers; and 3) the conservation genetics and geographic structure of legally protected and commercially important wild populations.  Our taxonomic focus is comparative vertebrate biology, especially globally distributed marine species and incorporation of fossil data.  New projects employ de novo genome mapping and molecular evolutionary analysis of global repeat content in all major clades of amniotes.  Reference genome assemblies are used to guide parallel cDNA and bisulfite methylation sequencing efforts to investigate tissue- and condition-specific differential gene expression and vertebrate transcriptome evolution.  These projects target locus-specific importance of mobile elements as agents of new gene function and novel regulatory pathways in the genomic neighborhoods of marine tetrapods.  They also provide insight into the systems biology of ecological communities being impacted by human activities and promote a more predictive vs. reactive approach to environmental management upon which we ultimately depend for our sustained public health.
