I'm an Postdoctoral Research Associate at Universidade Estadual de Campinas, under the BRIDGES collaboration. My research interests include, but are not limited to: geometric analysis, gauge theory, and Riemannian manifolds with special geometric structures. My collaborators past and present include Matt Turner (Bath), Daniel Fadel (UFRJ), Lorenzo Foscolo (Rome), Calum Ross (Edge Hill), and Derek Harland (Leeds). I finished my doctorate at University College London in 2022, under the supervision of Lorenzo Foscolo.
