Igor Schneider

Associate Professor


Igor Schneider received a BS degree in Biological Sciences from the Federal University of Para (Brazil) in 2003. He received a PhD degree in Genetics from the University of Iowa (USA) in 2009, and was a postdoctoral scholar at the University of Chicago (2009-2011).

Daniele Salgado de Sousa

(Advisor: Patricia Schneider)


Daniele Salgado obtained her technical degree in Fisheries at Federal Institute of Education, Science and Technology of Pará - IFPA (Bragança - 2012). She also graduated from Pará State University (Bragança - 2014) with a Natural Sciences degree in Biology. Later, she earned her master’s in Biotechnology at Federal University of Pará (UFPA, Belém - 2017); during this period, she developed research activities in Organic chemistry of biomolecules and metabolomics. Currently, Daniele is a PhD student in Neurosciences and Cell Biology (UFPA, Belém), working on the project entitled ‘Analysis of gene expression during ocular development and regulation of opsin asymmetry in Anableps anableps, four-eyed fish’.

Danielson B. Amaral

(Advisor: Igor Schneider)


Danielson Amaral obtained his degree in biology (BS) at Universidade Federal do Pará (UFPA, 2012-2017), during this period he was a visitor student at Indiana University Bloomington (USA, 2014-2015) through the Brazilian Scientific Mobility Program. Currently, Danielson is a master student in Genetics and Molecular Biology at UFPA and is interested in the evolution of vertebrate paired appendages, more specifically in the changes that happened during the transition from fins to limbs. To understand such changes he is working on the role of Sonic Hedgehog (Shh) during lungfish fin regeneration and comparative analysis of Shh limb-specific regulatory sequence.

Louise Neiva

(Advisor: Patricia Schneider)


Louise Neiva Perez received her BA degree in Biological Sciences at Centro Universitário do Estado do Pará (CESUPA, 2012). She was a master student in the Graduate Program in Neuroscience and Cell Biology, Universidade Federal do Pará (UFPA, 2015). While as a master student, she won best poster presentation award during the “VI International Symposium of Developmental Biology” (Paraty, RJ, Brazil, 2013) and best oral presentation award during the “II Symposium of morphophysiology of Amazon – UFPa, Brazil” (2014) for her work on eye development and gene expression on larvae of the four-eyed fish Anableps anableps. Currently, Louise is a PhD. Student in the Graduate Program in Genetics and Molecular Biology at UFPa working on “The genetic basis of the pigmentation pattern in primates of the new world, Alouatta belzebul, A. caraya e A. Seniculus”. In a broad sense she is interested in pigmentation of vertebrates.

Kellen Matos Veríssimo

Wainna R. B. Mendes

(Advisor: Patricia Schneider)


Wainna Barros is an undergraduate student majoring in Pharmacological Sciences at Universidade Federal do Pará. She is interested in spinal cord regeneration and its molecular mechanisms.
