Visiting Students


Erik Choueri

Erik is an ecologist who graduated from Universidade Estadual Paulista (UNESP Rio Claro-São Paulo/Brazil), and has Masters degree in Ecology from Instituto Nacional de Pesquisas da Amazônia (INPA-Manaus/Brazil). He is currently a Ph.D. student in the Genetics, Conservation, and Evolutionary Biology program at INPA and a visiting student at The City College of New York.


In his graduation project, he used molecular tools to understand the population dynamics of gray dolphins in an estuarine region in southeastern Brazil. During his Masters, he investigated the phylogeographic patterns of Antbirds that occupy riverine islands in the Amazon Basin. Currently, he is using a phylogeographic endemism approach to identify areas with an accumulation of lineages of small vertebrates (rodents, marsupials, and lizards) in the Amazon, and identifying the historical drivers responsible for these patterns. He is interested in biogeography, phylogeography, population genetics, and the evolution of neotropical organisms.


Lidia Martins

Lidia graduated with a Bachelor degree from Pontifícia Universidade Católica do Rio Grande do Sul (PUC-RS/Brazil) and has her Master degree in Animal Biology from Federal University of Rio Grande do Sul (UFRGS/Brazil). In her Master's she used population ecology to evaluate the conservation status of a lizard species endemic to the coastal zone of Rio Grande do Sul (Brazil) by monitoring three of the four known native populations using mark-recapture models.

Now, she is a PhD candidate in Ecology at the National Institute of Amazonian Research (INPA-Manaus/Brazil). She is interest in understand how natural populations have responded to past climate change and refine models to infer species extinction risks and adaptive potentials due to future global climate change. Lidia joined the Carnaval Lab with a Fulbright Fellowship to work on her PhD project for 9 months (2019-2020).
