I have a degree in Biological Sciences from the Federal University of Rio de Janeiro (UFRJ), a Master's degree in Biological Sciences (Botany) from the National Museum/UFRJ and a PhD in Botany/Plant Anatomy from the University of São Paulo (USP). I am an Associate Professor at the Federal University of Mato Grosso do Sul where I work in undergraduate teaching, research and extension activities. I am currently responsible for the administration of the Botany Laboratory. I am currently part of the permanent faculty of the Master's Program in Plant Biology (Campo Grande Campus) and the PPG in Frontier Studies (Pantanal Campus) at UFMS. I collaborate with PPG in Horticulture (Horticultura- UNESP/Campus Botucatu) in anatomical studies of agronomic varieties of hops. I also collaborate in research and extension projects at the Laboratory of Environmental Biotechnology/Institute of Biological Sciences/UERJ on plants from the Atlantic Forest. I have experience in Plant Anatomy, with an emphasis on species from the Pantanal, Cerrado and Chaco, medicinal and phytoremediating plants, addressing functional, taxonomic/systematic aspects. I work as a reviewer of articles in national and international scientific journals, and also as a volunteer member of the editorial board.

Graduated in Biological Sciences from the Federal University of Rio de Janeiro (1977), Master's in Biological Sciences (Botany) from the Federal University of Rio de Janeiro (1984) and PhD in Biological Sciences (Botany) from the University of São Paulo (2001 ). He is currently adjunct professor iii at the Federal Rural University of Rio de Janeiro, associate professor i at the Federal Rural University of Rio de Janeiro, deputy head of the botany department at the Federal Rural University of Rio de Janeiro, associate professor iii at the Federal Rural University of Rio de Janeiro. Rio de Janeiro, associate professor i at the Rio de Janeiro Botanical Garden Research Institute, collaborating professor - National Museum and associate professor iii at the Federal University of Goiás. He has experience in Botany, with emphasis on Phanerogamous Taxonomy, working mainly on the following topics: sapindaceae, plant taxonomy, floristics, Atlantic forest and marambaia.
Paullinia is a monophyletic genus of lianas with a neotropical distribution, encompassing approximately 220 species. In Brazil, there are 102 species occurring mainly in the phytogeographic domains of the Atlantic Forest and Amazonia. The species of this genus have diverse uses as psychotropics, bactericides, antioxidants, fish poisons, stimulants and for ritualistic purposes. The genus is nevertheless insufficiently studied from the anatomical and histochemical standpoints. In the present study, morphoanatomical and histochemical investigations were made of the leaves of Paullinia dasygonia Radlk., P. micrantha Cambess. and P. trigonia Vell. The species studied have very similar leaf characters which makes their identification difficult. The leaves have dorsiventral structure, collateral vascular bundles and both non glandular and glandular trichomes which vary in the species as regards shape, length and distribution. The glandular trichomes have neutral polysaccharides and phenolic compounds. In addition, laticifers were observed containing lipid droplets, alkaloids, proteins and phenolic compounds in diverse regions of the leaf. Saponins, which are characteristic of the family, were observed in the secretory trichomes and generally in the mesophyll and midrib. The results obtained provide evidence justifying further pharmacological investigation of these three species, as well as others in the genus.
