Evolution Research

Gainesville Campus

Main Research Goals

I am interested in how gene expression is regulated to pattern anatomical structures during vertebrate embryonic development.

By understanding the mechanism of regulation of gene expression, we can begin to understand how complex anatomical structures form in evolutionarily divergent species and how medical disorders occur in humans.

Potential Roles for Students

Students working with me will obtain experience in the following:

  • Bioinformatics-based programs (CLUSTAL, VISTA, etc.)
  • In situ hybridization for tissue-specific gene expression
  • Light microscopy
  • Embryo manipulation
  • DNA/RNA extraction
  • PCR
  • RT-PCR
  • Plasmid DNA production and transformation
  • Morphometric analysis of cellular and subcellular activities (e.g. cell shape, cell polarity)
  • Molecular phylogenetics
