Dr. David Houle is currently recruiting new graduate students for Fall 2016.
Research and Professional Interests:
I am an evolutionary geneticist, currently studying the evolution of development and how it affects morphology. The biggest unknowns in biology are the paths through which genetic variation affects the phenotype, and in turn how the phenotype affects organismal fitness. I believe that we need to greatly increase our ability to measure phenotypic characteristics, the phenome, before we can understand this genotype-phenotype-fitness map. We use phenomic approaches in Drosophila melanogaster, the fruit fly, to get at these questions, using a combination of molecular, genetic, and whole-organism techniques. Our current projects characterize the variation produced by particular genes and developmental mechanisms, characterize the genetic variation in natural populations, and seek to explain how that variation can be used to produce evolutionary responses. I have undertaken a wide variety of other projects in the past, and I am still interested in mutation, sexual selection, life history evolution, fluctuating asymmetry and measurement theory.Selected Publications:
