Programa de Pós-Graduação em Bioquímica – Graduate Program in Biochemistry

Prof. de Almeida holds an undergraduate degree in Biological Sciences from the Universidade Federal de Santa Catarina (1998) and a doctoral degree in Biological Sciences (Biochemistry) from the Universidade de São Paulo (2003). He carried out postdoctoral research at the Universidad de Córdoba, Spain (2004), in the area of environmental toxicology, and at the CSIC in Barcelona (2013). He is a Professor at Fundação Universidade Regional de Blumenau (FURB), a permanent professor at PPGBQA since 2022, and a CNPq 1C Research Productivity Fellow.

“His research is focused on Environmental Toxicology and on Biochemistry/Physiology of human diseases, with an emphasis on the study of oxidative stress in sickle cell diseases“

Ongoing Projects:

a) Evaluation of the negative effects of rice pesticides used in the region of Vale do Itajaí (SC) on tadpoles of native frogs.
b) Pilot diagnosis of contamination of coastal environments in Santa Catarina by emerging pollutants and their potential effects on marine bivalves.
c) Biochemical changes in bullfrog tadpoles exposed to sugarcane herbicides under different temperatures.
d) Evaluation of the effects of tebuthiuron herbicide on thyroid metabolism and oxidative stress parameters of bullfrog tadpoles under different temperatures.
