Roisin McGarry

Research Assistant Professor

Roisin McGarry has a 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 national scholarship from the Natural Sciences and Engineering Research Council of Canada. She conducted post-doctoral research at the University of North Texas, and was a visiting scholar 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 with the goal of enhancing crop productivity.

CURRENT RESEARCH INTERESTS

Using non-model, woody perennials, McGarry's research aims to:

  • Develop tools to elucidate and manipulate architecture regulation

  • Investigate meristematic signals regulating patterns of indeterminate and determinate growth

  • Explore the genetic networks regulating meristem size and fate
