As a part of the Center for Bioinformatics and Integrative Biology, the Molecular Biophysics and Bioinformatics Group is a interdisciplinary group whose main objective is to develop research strategies to answer biological questions — but not limited to — combining theoretical and experimental approaches at the interface of bioinformatics and biophysics.

Nowadays, our group main research area is to describe the interaction between bacterial membranes and antimicrobial molecules with the final objective of developing new strategies against antimicrobial resistance. To achieve this objective, our group combines Molecular Simulations methods with Biophysical and Biological Assays using Lipopolyssacharides of genetically modified bacteria.

More than a Lab! a Virtual Space for Integrative Science, the integrative focus of our group offers an iterative cycle of research, in which biological problems are tackled using a variety of theoretical and experimental approaches, based in the observation, systems characterization, parametrization, simulation and experimental validation.

This  cycle requires a group of expertise’s, with strong knowledge on biochemistry, biophysics, bioinformatics, computational chemistry, chemistry, among others. Our group try to cover all this fields, which allows us not to be limited to be a place for experiments, but a virtual space to gather people or use equipments to solve every day problems and answer scientific questions.
