I am a herpetologist and biogeographer. Currently, I am a Professor at the São Paulo State University (UNESP, campus of Rio Claro) where I coordinate a Young Researcher FAPESP project and I am also an Associate Researcher at the Gothenburg Global Biodiversity Center at the University of Gothenburg (GGBC; Sweden). I am interested in to understand the patterns of distribution of biodiversity and how these patterns changed along time and space. I investigate these subjects on global, regional and local scales by integrating species distribution datasets with phylogenies and traits of the biota, with implications for conservation. Thus, my studies include analysis of biodiversity (patterns of richness, phylogenetic diversity and endemism, functional diversity), biogeography (mapping species distribution, regionalization, history and conservation), macroecology and modelling of species distribution (niche evolution, changes of species distribution under climate change scenarios). I also investigate topics related to natural history, taxonomy, reproductive biology and behaviour. I use mainly amphibians and reptiles (herpetofauna) as models in my studies. In 2021, I became the author of the List of Reptiles of Brazil, published periodically by the Brazilian Society of Herpetology. Part of the editorial board: Frontiers in Ecology and Evolution (Biogeography and Macroecology), Journal of Herpetology and Systematics and Biodiversity.

Trans-disciplinary biogeography is the ideal science to understand patterns and processes that generated and maintain groups of highly complex and diverse organisms, such as amphibians and reptiles (herpetofauna), especially those that inhabit tropical regions of the globe. Advances in recent decades allowed for the huge accumulation of data on herpetofauna and important discoveries. Howe…
Biogeography focuses on recognizing the processes and patterns that promote biodiversity distribution. On a large scale, these patterns are relatively well established, however, intracontinentally, there are still gaps in neotropical regions. Thus, there are new opportunities for studies that search to understand the processes that influence species distributions. Among the important proc…
Sleep biology in snakes as well as its ecological and behavioral aspects is unknown for most species, especially for the Neotropical species. The fact that snakes present a state similar to what is considered "sleep" has been demonstrated by behavioral observations, but the pattern of brain activity of snakes during the inactive state is almost absent. Furthermore, the place where snakes …
Identifying knowledge gaps is an important factor in designing effective conservation strategies. These scientific shortfalls can be indicated by deficits known to science as Wallacean (i.e., geographic distribution), Darwinian (i.e., evolutionary relationships), Linnean (i.e., taxonomic knowledge), among others. Such gaps are caused by sampling biases that can be explained by some aspect…
The so-called Mid-North region of Brazil, located mainly in the state of Maranhão, extends from the 6 degrees south, 42 to the 46 west and is limited by the Atlantic Ocean to the North. The region has a complex landscape, due to the contact between the Caatinga, Amazon and Cerrado biomes, the latter a biodiversity hotspot. It brings together unique phytogeographic and climatological chara…
The emergence of the "Alphonse Richard Hoge" snake collection is intertwined with the history of the founding of the Butantan Institute itself, in 1901. Since its inception, it has been an active and continually growing collection. For a long time it was considered one of the most prominent collections in the world and certainly the most significant in the Neotropical region, with around …

Sleep is a fundamental state observed in the animal kingdom and characterized by distinct physiological and behavioral changes. Despite the dangers associated with sleep (e.g., predation), the benefits, such as improved cognitive function and physical performance, outweigh the risks. Defining sleep in snakes is particularly challenging because traditional sleep interpretations are establi…
Identifying and highlighting gaps in knowledge is an important aspect in understanding macroecological processes and in to designing effective conservation strategies. One of the major impediments to assessing the conservation status of species and making conservation decisions is the lack of data regarding geographical distribution of species, scientifically known as Wallacean shortfall.…
The identification of natural biogeographical regions is fundamental for comparisons in broad-scale ecological and evolutionary studies, and constitutes an essential tool for conservation planning. Several recent ecological and biogeographical studies have attempted to delimit bioregions at both global and local scales, and there is a long history of regionalization schemes proposed for t…
