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). Currently, Dr. Schneider is developing the South American lungfish as a model species for comparative developmental biology and regeneration.

Patrícia Schneider

Associate Professor


Patricia Schneider received a BS degree in Biological Sciences from the Federal University of Para (Brazil) in 2003. She received a PhD degree in Genetics from the University of Iowa (USA) in 2010, and was a postdoctoral scholar at the University of Chicago (USA from 2010-2011. Currently, Dr. Schneider’s group is working on producing genetic tools and characterizing the developmental stages of the four-eyed fish Anableps anableps, with a special focus on opsin gene expression during eye development.

Aline Cutrim Dragalzew

(Advisor: Igor Schneider)


Aline Dragalzew graduated in Biological Sciences (BA) at Universidade Federal de Londrina (Brazil, 2010). She earned her master's degree in Cellular and Molecular Biology from the Faculdade de Medicina de Ribeirão Preto da USP, FMRP-USP (Brazil, 2013). She earned her PhD also at Faculdade de Medicina de Ribeirão Preto da USP, FMRP-USP (Brazil, 2017), supervised by Prof. Dr. Tiana Kohlsdorf. During her doctoral studies, she received a sandwich Doctorate scholarship for research at the University of Washington (supervised by Prof. Dr. Chris T. Amemiya). Currently, she is a postdoctoral scholar working on the fin and limb regeneration in vertebrates.

Kellen Matos Veríssimo obtained a BS degree in Biological Sciences (2012) and master’s degree in Biotechnology (2015) from the Federal University of Pará (Brazil). Currently, she is a doctoral student working on the tail and spinal cord regeneration in South American and African lungfishes.

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.

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.

Undergraduates Students


Rafaela Ribeiro

(Advisor: Patricia Schneider)


Rafaela is an undergraduate student, majoring in Biology at University the Amazonia (Belém, PA).

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. Salamanders are well known for such ability, yet Wainna is focusing on lungfish spinal cord regeneration as a possible model for future research. She aims to find common ways vertebrates use to regrow such a delicate structure as it has important implications for medical research.
