Personal profile


I am originally from Brazil, where I did my Bachelor of Science and my Master of Science degrees. I moved to Perth to start my PhD at the Centre for Evolutionary Biology (University of Western Australia) in 2009. I finished that degree in 2013, and started working as a Postdoc Research Associate at the same university. Below the details of my education and employment:


2013 – present — Postdoctoral Research Associate at the Centre for Evolutionary Biology; School of Animal Biology


2009 – 2013 —PhD in Animal Science (Centre for Evolutionary Biology), School of Animal Biology, University of Western Australia, Perth - Australia. Thesis title: “The evolution of male dimorphism in arthropods” Supervisors: Leigh W. Simmons and Joseph L. Tomkins.

2006 - 2008 — MSc in Ecology, Institute of Biology, Campinas State University (Unicamp), Campinas - Brazil. Thesis title: “Reproductive biology of the harvestman Acutisoma proximum (Arachnida: Opiliones): alternative mating strategies among males and maternal care by females” Supervisor: Glauco Machado.

2001 – 2005 — Licentiate in Biological Sciences, Campinas State University (Unicamp), Campinas - Brazil.

2001 – 2005 — Bachelor in Biological Sciences, Campinas State University (Unicamp), Campinas - Brazil.

Currently, my main research interest is male dimorphism, a phenomenon that often reflects alternative reproductive tactics among males: the large male morphs typically guard females or reproductive territories and have more elaborate weaponry; the small male morphs sneak copulations and have reduced weaponry. Male dimorphism is particularly common among arthropods, and usually results from a polyphenism: the differential expression of alternative phenotypes from a single genotype depending upon environmental conditions. I have been investigating several questions about polyphenic male dimorphism with experiments using mites, harvestmen, and dung beetles.
My interest in the evolution of alternative mating tactics and male dimorphism led me into the topic of phenotypic plasticity. Therefore, in the last 5 years, part of my research has focused on threshold traits (polyphenisms), usually from a quantitative genetics perspective.
Moreover, I am also interested in the behavioral ecology of insects and arachnids, especially their reproductive biology. My research includes the evolution of parental care, mating systems, sperm competition, and social behavior.
