2003 – PhD, Weizmann Institute of Science (mentor: Prof. Robert Fluhr)

Research Summary

Our lab investigates fundamental aspects that regulate plant growth and development. Using both classical and state-of-art tools, we study the role of hormonal signaling, tissue identity and mechanical constraints, that together dictate a developmental output. In parallel, we investigate how these processes are tuned by distinct environmental conditions.
