We study the cellular and molecular mechanisms of plant regeneration, adventitious root formation, and transcriptional regulation.

Our research examines how cells acquire organ identity and establish tissue patterns during regeneration and de novo organ formation. We combine developmental genetics, microscopy, and genomic analysis in Arabidopsis and tomato.
We investigate how intercellular signaling, plasmodesmatal connectivity, and sugar transport regulate root tip regeneration. Our work examines the coordination of cell identity transitions, tissue repatterning, and metabolic resource allocation after injury.
We study the specification of root founder cells and the initiation of shoot-borne roots in tomato. We examine the conserved genetic programs that regulate above- and belowground root initiation.
We identify conserved noncoding sequences across plant genomes and investigate their roles in developmental gene regulation. Our work combines comparative genomics and functional analysis of cis-regulatory elements, with an interest in synthetic promoter design.
