Strategic Focus

In the Biophysics Group, we use the tools of physics and mathematics along with computational models to study biological systems in general. Our short-term goal is to impact the areas of muscle electrophysiology, biophotonics, and cell membranes with new ideas and well-designed experiments and theoretical models that permit us to have a more comprehensive understanding of these systems.

Research Lines and/or Areas

Highlighted Projects

Study of the polarized iridescence in the wings of Morpho butterflies: a behavioral and structural approach (February 2020 — to date).
Study of the action mechanism of the venom of arachnids through the patch-clamp technique (February 2019 — present).
Development of a cardiomyocyte cell membrane model that allows morphological and physicochemical changes produced by anticancer drugs (February 2017 — present).

Key Research Findings

The creation of the first cell electrophysiology laboratory marked a milestone for the University, as it is the first of this type in the city and one of the three active laboratories in Colombia.
The following work was the cover of the journal and was mentioned in a separate section within the same journal (Inside JEB), where the story behind the article was told (its conception, the researchers involved, etc.) Coloration mechanisms and phylogeny of Morpho butterflies (in Journal of Experimental Biology). DOI: 10.1242/jeb.148726
