Roisin McGarry

Research Assistant Professor

Roisin McGarry is a Research Assistant Professor in the BioDiscovery Institute at the University of North Texas. She earned her BSc from the University of Lethbridge, Canada, MSc from the University of Alberta, Canada, and PhD from Cornell University. Her doctoral research was awarded a prestigious national scholarship from the Natural Sciences and Engineering Research Council of Canada. She conducted post-doctoral research at the University of North Texas, and carried out professional development leaves at the Max Planck Institute of Molecular Plant Physiology, Germany, and the University of Georgia. McGarry's research in plant development is focused on architecture regulation in crop plants, including cotton, with the goal of enhancing productivity.


  • Developing tools for gene functional analysis in non-model plants
  • Understanding plant architecture regulation to enhance and optimize crop productivity in region-specific contexts
  • Exploring signaling networks specifying architectures using transcriptomic and genetic approaches
