Universidade de São Paulo (USP). Faculdade de Ciências Farmacêuticas de Ribeirão Preto (FCFRP) (Institutional affiliation from the last research proposal) Birthplace: Argentina
Holds a degree in 'Bachiller Universitario con mención en Química' (2005) and a bachelor's degree in 'Licenciatura en Biotecnología' (2009) from the Facultad de Ciencias Bioquímicas y Farmacéuticas, Universidad Nacional de Rosario (FBioyF-UNR), Argentina. He earned his PhD in Biological Sciences (Doctor en Ciencias Biológicas) at the same institution in 2014, conducting research on the bacteria-host interface, with a focus on protein complexes and their functional mechanisms in phytopathogenic processes.Between 2014 and 2019, he worked as a postdoctoral researcher at the Instituto de Química, Universidade de São Paulo (IQ-USP), under the supervision of Prof. Shaker Chuck Farah. During this time, he deepened his studies in molecular biology, structural biology, and microbial genetics, focusing on protein complexes involved in biologically relevant microbiological processes. He also collaborated on multidisciplinary projects with research groups in Brazil and abroad.He has teaching experience since 2008, when he began teaching the course 'Una propuesta para leer, escribir, y aprender mejor en el ingreso a la Universidad' (20082010). He served as an assistant in the Departamento de Química Orgánica at the Facultad de Ciencias Bioquímicas y Farmacéuticas (20102012) and in the disciplines of Cell Biology and Bromatology Laboratory (20122013) of the 'Técnico Universitario en Química' program at Instituto Politécnico Superior "General San Martín," affiliated with the Universidad Nacional de Rosario. These experiences solidified his pedagogical background and enhanced his ability to integrate teaching and research.He conducted a research internship (20162017) at the Department of Biological Sciences, Birkbeck College (BBK), University of London, United Kingdom, where he held the position of Associate Research Fellow. There, he collaborated with leading teams in structural biology, employing advanced techniques such as cryo-electron microscopy to investigate fundamental molecular mechanisms.Currently, he is an Assistant Professor in the Department of Biomolecular Sciences at the Faculdade de Ciências Farmacêuticas de Ribeirão Preto, Universidade de São Paulo (FCFRP-USP), where he leads innovative projects focused on the structural and functional characterization of molecular systems in microorganisms and viruses. His research areas include structural virology, studies on protein-protein interactions, and bacteriophage infection mechanisms. He coordinates the Laboratory of Structural Studies of Macromolecules (LEEM) and plays an active role in training new researchers, supervising undergraduate, master's, and doctoral students.With solid experience in molecular biology, structural biology, biochemistry, and microbial genetics, he develops studies with potential applications in medical, pharmaceutical, and agricultural fields. He maintains collaborations with national and international research institutions and is recognized for the quality and impact of his scientific contributions.Contact: ggsgro(at)usp.br (Source: Lattes Curriculum)

Bacteriophages (phages) are viruses that infect bacteria, and are the smallest and most abundant biological entities on Earth. To replicate, they use the bacterial host machinery to either i) immediately produce new progeny after infection which leads to the death of the infected cell (lytic pathway), or ii) integrate into the bacterial chromosome as a prophage which allows establish a sy…
Bacterial secretion systems are large membrane structures (in the range of MegaDaltons) formed by multi-protein complexes. To date, nine secretion systems have been identified and characterized (in some cases partially) in a small number of all bacterial species, from which scientists and researchers seek information to understand other species or system under investigation. It is seen th…
Among the total viral population, bacteriophages (phages) are viruses that thrive by infecting bacteria. In recent decades, recognition of the roles and applications of phages has gained prominence, ushering in "The Third Era of Phages". The phage infection process is highly dynamic, especially the early steps involving adsorption and genome delivery, both critical steps for successful in…
The creation of minicells for visualizing cellular structures using electron microscopy methodologies (mainly cryo-electron tomography, cryo-ET) is already a well-known and effective approach, allowing greater visualization of details in the tiny pseudo-cells. In X. citri, a bacterium relevant for its impact on citrus agriculture and as an increasingly established model for the study of c…
Currently, bacteria that are multi-resistant to conventional treatments pose a worldwide health problem. The medicinal antibiotics used have few structural differences, making it easy for new cases of resistance to arise. Therefore, new treatment proposals must be carefully developed and explored. In this regard, the study of bacteriophages is on the rise. Bacteriophages, or phages, are h…

Type IV pilus (T4P) is a thin, flexible, and resistant filament located on the surface of bacterial cells. This appendix is involved in different bacterial behaviors, including twitching motility, adhesion to surfaces, natural transformation, biofilm formation, protein secretion, and chemotaxis. It has been previously demonstrated that infection of the phytopathogen Xanthomonas citri (Xac…
The bacterial type IV secretion system (T4SS) is a large megaDalton protein complex involved in the transport of DNA and proteins across the cell envelope. Apart from its well known role in bacterial conjugation, many T4SSs are responsible for the transfer of virulence factors into host cells and are therefore important objects of study in the combat against disease in animals and plants.…
One of the main objectives of this postdoctoral project is to obtain structural information regarding the Xac Type IV Secretion System core complex, which forms the pore through both the inner and outer membrane layers of the bacterial envelope. This complex is made up of 14 copies each of VirB7, VirB9, and VirB10 subunits. Due to the core complex's large size (~1.2 MDa) and association w…
