Welcome to the group of Professor Julio Caballero, at Universidad de Talca in Chile.
The work of my group includes the application of computational methodologies to study complex biomacromolecular systems, mainly focused to the description of the interactions between proteins and small molecules. We are interested in the analysis and processing of available chemical structures of proteins to generate novel chemical information, with potential applications in the design of novel bioactive compounds. Our applications include docking, molecular dynamics, QSAR, hybrid QM/MM methods, free energy calculations, artificial intelligence, and predictive models.
The work of our group is inserted in the fields of computational biochemistry, pharmaceutical modeling, protein structure and function, enzyme reactivity and selectivity, and our contributions are mainly focused to medicinal chemistry topics.
