My research focuses on how the interactions of mitochondrial and nuclear genes shape the evolution of eukaryotes.  I am particularly interested in the role of mitonuclear interactions in the processes of sexual selection and speciation.  For many years, carotenoid coloration has been a focused interest in my lab group, and we are currently studying the connections between the female mate choice, carotenoid metabolism, cellular respiration, and mitonuclear compatibility.

Subject areas:

  • Evolutionary Genetics & Systematics,
  • Behavior, Ecology, Evolution, and Conservation,
  • Physiological Adaptations and Functional Genomics, Host-Microbial Interactions.

Trained as an evolutionary and behavioral ecologist, Geoff leads an integrative research program investigating the function and evolution of animal ornamentation.

His current research interest is the co-adaptation and co-evolution of mitonuclear elements within eukaryotes.

My focal interest is the evolution of ornamental traits in animals. My attempts to explain colorful feathers in birds have guided me to studies of mate choice, carotenoid biochemistry, cell biology, mitonuclear genomic interactions, free radical biology, and, most recently, speciation.

Research in the Hill lab:

  • Carotenoid Coloration & Color Genetics
  • Sexual Selection Theory and Mitonuclear Mate Choice
  • Mitonuclear Compatibility Species Concept
  • Individual condition and mitochodnrial function
  • Habitat Use and Conservation
  • Ivory-billed Woodpeckers
  • AU MitoMobile.

The Hill lab has a growing interest in the performance of mitochondria.
