Teresa Escalante Muñoz is a member of the academic division of the Clodomiro Picado Institute, and a teacher at the Immunology Section of the Faculty of Microbiology, University of Costa Rica.

Her research focuses in the local and systemic pathology induced by snake venoms, mainly the effects caused by hemorrhagic metalloproteinases, which are toxins from viper venoms that destroy blood capillaries. Some of her work has delved into the mechanism of action of metalloproteinases, studying the alterations induced by these toxins on the extracellular matrix and microvessels, in both, in vitro models and animal models. She has also studied natural and synthetic inhibitors of these toxins, in the search for therapeutic alternatives to complement the antivenom serum therapy.
