Looking for a PhD student to help uncover whether our arms and legs, and those of insects, share the same core gene-regulatory network. The work will be performed in the appendages of butterflies in collaboration with Suriya Murugesan and Tom Carney, working on zebrafish fin development. The goal of the project is to try to identify (functionally) homologous regulatory sequences from shared appendage genes across the two species. If interested, please contact me (antonia.monteiro@nus.edu.sg). Graduate Program application deadline is 15 Nov 2026 (https://www.dbs.nus.edu.sg/education/graduates/doctor-of-philosophy/) . An interest in evo-devo, especially in deep questions about body plan evolution is essential, as well as some undergraduate training in genetics, evolution, and developmental biology.
