Intro

I am interested in exploring how environmental variation and biotic stressors affect physiological and behavioral response of microbes, plants, and insects, as well as the implications at the population and community levels. My research integrates the following fields:

Ecology and Evolution Microbiomes/Viromes under Environmental Extremes

Applications: Bioremediation

Interactive Stressors -abiotic and biotic.

Extreme Temperatures-Pollution-Pathogenic Infections

Behavioral Ecology: Foraging-Experimental Methods

Behavioral ecology: trial-error dynamics

Global Change Effects on Chemical Biocommunication

Conservation Physiology

Ecotoxicology and Management of Species

I am an integrative biologist, primarily interested in interactions among ectothermic organisms (microbes, plants, insects, frogs) and the environment. My research focuses on the physiological and behavioral mechanisms underlying the host-parasite interactions in natural and managed ecosystems.

I have adopted an integrative approach that combines functional genomics, physiology, chemical ecology, behavioral ecology, population and community ecology, and artificial intelligence.

I earned my Ph.D. from Pennsylvania State University and my BS in Biology at the National University of Colombia.
