Research Description

Auxin is a major plant hormone that plays instructive roles in almost every aspect of plant biology, including cell growth and fate. Depending on the context, auxin action can lead to different developmental outcomes. How this is achieved is not well understood. My research program explores how auxin signaling modules control diverse developmental processes in Arabidopsis. I am applying a variety of molecular approaches to these studies, including RNA-seq, Ribo-seq, proteomics and phenotyping. Such multi-scale integration will elucidate new aspects of auxin biology, including links between different aspects of gene regulation and identify novel regulators of plant development.
