My research interests are in the field of evolutionary genetics, especially in processes occurring at or influenced by the genome. Active research projects in the lab are primarily concerned with using the fly species Drosophila americana to understand the factors influencing chromosomal change and...

The Logsdon lab works on a variety of related topics in molecular evolutionary genetics: SEX & MEIOSIS: Exploring the origin and evolution of meiotic genes in diverse eukaryotes. Molecular evolution and phylogeny of meiotic genes. Isolation of meiosis-related genes from protists and other eukaryotes...

Transcriptional enhancers are DNA sequences that specify inducible, spatiotemporal patterns of gene expression at most gene loci. Several complementary results from genomic studies have shown that the majority of functional sites in a genome correspond to transcriptional enhancer sequences, thus...

We apply a multidisciplinary approach-combining empirical work to obtain sequence data, large-scale genomic analyses, and the development of theoretical, analytical and computational tools-to investigate: 1) variation in the efficacy of natural selection among species and across genomes, 2) the...
