Mariana Abrahão Bueno de Morais is a researcher in the Brazilian Biorenewables National Laboratory (LNBR) from the Brazilian Center for Research in Energy and Materials (CNPEM). She has been focused on the elucidation of enzymes molecular mechanisms, integrating experimental data with computational approaches, including molecular modeling, classical and Quantum Mechanics simulations. She obtained a degree in Biotechnology Engineering at the São Paulo State University and her PhD (emphasis in Biochemistry) at the State University of Campinas, developing the project at CNPEM (Brazil) under the supervision of Mario Murakami, with a period at the IBMC/I3S Institute (Portugal) under the supervision of Prof. Ana Tomas. Mariana did a postdoc at the University of Barcelona in the group of Prof. Carme Rovira (QSBio), working with hybrid QM/MM simulations.

Mariana has contributed to studies related to members of the following CAZy families:
GH1 [1, 2, 3], GH2 [4], GH5 subfamily 57 [5], GH26 [6], GH38 [7], GH39 [8], GH43 [9, 10, 11], GH51 [12], GH173 [13], CBM3 [14], CBM89 [13].
