We study microorganisms and biomolecules to explore new applications in biotechnology, health and agriculture.
At the Molecular Microbiology Laboratory of the Faculty of Chemistry, Universidad de la República, we study microorganisms, enzymes and other biomolecules to understand their functions and explore applications in biotechnology, health and agriculture. We combine experimental microbiology, molecular biology, genomics, bioinformatics and protein engineering. Our research spans biocatalysis and biomolecule production, the search for antimicrobial compounds and peptides, and interactions between microorganisms and plants. We integrate research with undergraduate and graduate training, involving teams from different disciplines and institutions.
Six researchers working together across research areas and disciplines.
01Teaching and research assistant · Grade 2 · Full-time dedication
Antimicrobial peptides
She studies antimicrobial peptides from native plants and actinobacteria, combining recombinant production, functional characterization and the study of mechanisms of action, with potential applications in microbial control and infection diagnosis.
02Teaching and research assistant · Grade 2 · Full-time dedication
Mineral nutrition and plant resistance
She studies how environmental factors and mineral nutrition influence plant resistance and disease. Her research examines their effects on bacterial virulence, colonization, microbiomes and the molecular responses of the organisms involved.
03Teaching and research assistant · Grade 2 · Full-time dedication
Genome mining and biocatalysis
He investigates the biosynthetic diversity of actinobacteria from extreme environments through genome and metagenome mining. His work seeks to identify biosynthetic pathways and candidate enzymes for developing bioactive compounds and biotechnologically relevant transformations. He co-leads the biocatalysis for bioactive molecules research area with Sonia Rodríguez Giordano and participates in bioinformatics and biocatalyst design.
04Teaching and research assistant · Grade 2 · Full-time dedication
Bioinformatics and protein design
She studies enzyme and protein design and optimization using bioinformatics and artificial intelligence, combined with experimental validation. Applications include biocatalysts for drug and radiotracer synthesis, and proteins that bind to microorganisms.
05Associate Professor · Grade 4 · Full-time dedication
Biocatalysis and metabolic engineering
She studies the use of enzymes to synthesize bioactive molecules and the development of microorganisms that produce biomolecules. Her research combines biocatalysis, metabolic engineering and yeast expression platforms.
06Assistant Professor · Grade 3 · Full-time dedication
Plant pathogens and biological inputs
She studies plant-pathogenic bacteria, their interactions with plants and strategies for disease management. Her work combines epidemiology, molecular diagnostics, genomics and microbiome research with the development of biological inputs for plant health.
From microbial diversity to protein design and plant health.

Research leadCésar Iglesias
We explore genomes and metagenomes to identify biosynthetic gene clusters (BGCs) and prioritize candidates for experimental characterization. We seek metabolites with potential bioactivity and enzymes that transform tryptophan-derived compounds, including halogenases, imine reductases and N-methyltransferases.

Research leadMariana Barraco Vega
We identify, produce and characterize antimicrobial peptides, including defensins from native plants and peptides from Antarctic actinobacteria. We study their activity and mechanisms of action against microorganisms of clinical, agricultural and food-related interest, and explore variants for infection diagnosis through molecular imaging.
