Dr Juan C. Garcia-R BSc, MSc, PhD

Research Officer

School of Veterinary Science

I am an evolutionary ecologist interested in macro- and micro-evolutionary studies to help understand the modes of diversification in different eukaryote groups. My research experience has focused on working at or across any level of ecological organization ranging from molecules to ecosystems in broad areas of interest including, but not limited to, phylogenetics, population genetics, phylogeography, community ecology, macroecology, and bioinformatics.
