I carried out my undergraduate studies in Chemistry (Universidad Distrital Francisco José de Caldas – 2009) and Pharmacy (Universidad Nacional de Colombia – 2012) in Colombia. Then, in 2016 I finished my PhD in Applied Sciences at the Center for Bioinformatics and Molecular Simulations at Universidad de Talca – Chile, where I studied the structure-function relationship and the molecular pharmacology of ion channels and other membrane proteins using theoretical and experimental approaches.
I joined Argüello’s Lab to unravel the mechanisms of copper homeostasis in bacteria focused on membrane proteins by using biochemistry and system biology methods as well as structural bioinformatics approaches.
