My first contact with research was as a second year undergraduate student at Dr. Sergio Vanin's lab in USP (Brazil), where my main task was to organize the lab beetles collection. The huge diversity of shapes among beetles groups surprised me and, since then, I have paid attention to relationships between form and function in organisms and to evolutionary patterns. In my masters dissertation work I studied the phylogenetic relationships of species of harvestmen belonging to the family Gonyleptidae (Opiliones). For that I built a phylogeny using only behavioral, ecological, and chemical characters. This project was a great opportunity to experience how shared ancestrality can shape both ecology and morphology and its influence on comparative studies. Recently I've joined Dr. Luke Harmon's lab at the University of Idaho as a PhD. Student. My main research interests are comparative methods, trait evolution, and patterns of diversification.
