Marcos is a first year PhD student in the Lanier Lab at the Sam Noble Oklahoma Museum of Natural History at the University Of Oklahoma in Norman. He is interested in phylogenetics, species delimitation, population genetics, genomics, bioinformatics, phylogeography and molecular evolution. 

Marcos received a Bachelor degree in Biology from Universidade Federal do Estado do Rio de Janeiro (UNIRIO) in 2014. During his time as a Biology undergraduate, he studied the genetic diversity of the rodent species Euryoryzomys macconelliusing DNA barcodes to verify whether populations separated by rivers in the amazon rainforest presented signs of genetic divergence. After finishing his undergraduate studies, he started applying species delimitation methods to better understand the potential biodiversity of the species within the genus Oligoryzomys, simultaneously testing how priors for branching patterns impact the results of species delimitation methods. During this same period between 2015–2017, he also worked at the Museu Nacional da Universidade Federal do Rio de Janeiro as a research assistant cataloging and organizing tissue samples stored in the mammalogy department under the supervision of Dr Marcelo Weksler who was also his academic supervisor between 2013–2019. In 2017, he started his masters in Evolutionary Biology and Biodiversity at the Universidade Federal do Rio de Janeiro (UFRJ) receiving his master degree in 2019. During this period, he assembled mitochondrial genomes to apply them in phylogenetic analysis to infer evolutionary relationships between subfamilies within the rodent Family Cricetidae and to test how different approaches of data partitioning affect the statistical support and topology of phylogenetic trees. Since August of 2019, he has been enrolled in the PhD program of Ecology and Evolutionary Biology at the University of Oklahoma as a student in Lanier lab at the Sam Noble Oklahoma Museum of Natural History. He has been working on a project to understand how demographic history shape the current genomic diversity that might be associated with adaptation of Collared Pikas (Ochotona collaris) to changes in environmental conditions.
