LEP - December - 2014


Daniel J. G. Lahr (DL)



Dan is the lead P.I. He is interested in an array of questions regarding protistan evolution and diversity. Dan has worked on protistology since his 1st undergraduate year, has done a masters in taxonomy of testate amoebae and his PhD in evolutionary biology, focusing on the amoebozoans as a study system.  He is currently trying to setup a laboratory of evolutionary eukaryotic microbiology, so better not ask about research. Seen here enjoying the company of fellow amoebologists in Poland, at the 7th ISTA.

Anush Kosakyan (AK)


Anush is a postdoc researcher at IB-USP. She is interested in general questions of taxonomy, systematics, phylogeny and evolution of testate amoebae. During her PhD she focused on taxonomy, phylogeny and ecology of arcellinid testate amoebae particularly focusing on family Hyalospheniidae. Her current objective is to investigate arcellinid diversity, and to reconstruct solid and precise phylogeny combining comprehensive taxon sampling, multiple genes and well documented morphological characters, which will lead to the discovery of new arcellinid taxa (lineages) and may be of crucial importance for understanding deep evolution of eukaryotes.



Alfredo P. Sousa (APS)

Alfredo is an undergraduate student at IB-USP. He is interested in evolution and morphometry of testate amoebae. He is working with natural populations and clonal cultures of Arcella vulgaris to analyze the temporal morphometric variability of these protists. He expects to determine range of morphometric variability temporally and evaluate how culturing impacts on variability within this species of testate amoebae.

Daniel Máximo (DMA) - TT3


Giulia Magri (GM)


Giulia is an undergraduate student IB-USP. She is interested in evolution, ecology and microbiology. She is currently trying to understand population distribution patterns in microorganisms, under the current microbiological paradigm – “Everything is everywhere”. She is testing hypothesis under this paradigm using a morphotype of testate amoebae to connect molecular evolution with population dynamics.

Luana Morais



Luana is a PhD student in the Geosciences Institute. She is interested in the evolution and of testate amoebae in the Neoproterozoic.  She is using modern tools to analyze microfossils found in the Corumba and Jacadigo groups (Paraguay belt, Brazil).  She hopes to be able to gain insights into the paleoecology at the end of the Precambrian.

Paulo Gonzalez Hofstatter - PhD student

PhD student investigating the evolution of meiosis and sex in testate amoebae and other Amoebozoans. Paulo has worked with taxonomy of Apicomplexan protozoa since his 3rd undergraduate year and during his MSc. He is interested in evolution and phylogeny of eukaryotic lineages using bioinformatics and molecular data.

Former Visitors


Quentin Blandenier (QB) - visiting Masters Student

Quentin was a visiting student coming from the University of Neuchâtel (Switzerland).  He is undertook a sandwich period at IB-USP from September-DEcember 2014 to achieve his Masters in Science degree.  He is interested in testate amoebae and general protistology. He comes to LEP-USP to learn about evolution and genomics. The Amoebozoa is one of the most poorly understood major eukaryotic and the main reason is the lack of « cheap and easy » molecular markers. The aim of his project is to survey mitochondrial markers for this group, to allow a deeper comprehension of taxonomy, phylogeny and evolution.
