Siobhan Brady

Siobhan Mary Brady is a Canadian molecular biologist who is a professor of Plant Biology at the University of California, Davis. Her research considers how plant roots experience their surrounding environment, with a focus on understanding the impact of climate change. Brady was elected Fellow of the American Association for the Advancement of Science in 2024.

Early life and education

Brady grew up in Ontario. She has said that she was surrounded with plants from a young age. Her high school English teacher and chemistry teacher encouraged her to pursue her curiosity. She had originally intended to creative writing, but settled on science, and became interested in plant biology. She studied molecular biology at the University of Toronto. She remained there for her doctoral research, and earned her doctorate in 2005. She studied how hormonal cues are integrated in root initiation. She used suppressor screens and mutant analysis to investigate genetic relationships. Her doctoral research considered the abscisic acid insensitive3 (ABI3) gene. She moved to Duke University as a postdoctoral researcher, where she studied gene expression patterns using microarrays of cells. She studied the COBRA gene family. She was named as one of the most outstanding postdoctoral researchers at Duke University.

Research and career

In 2009, Brady joined the University of California, Davis as an assistant professor. Her research has focussed on roots – specifically the Arabidopsis root – as a model for plant development.
