Listeria and other invasive pathogens

My first contact with research was while working in the Venezuelan Amazon with Amerindian populations and diagnosis/epidemiology of tuberculosis. During my master I worked on the dynamics of the Pseudomonas aeruginosa biofilm associated with prostheses and surgical surfaces. Then for my PhD, I worked on Mycobacterium abscessus, focusing on two main areas: Molecular mechanisms of drug resistance and cell wall biosynthesis and their impact on virulence using zebrafish as a model of infection. I am currently working on the functional genomics of Listeria to stress associated with the food chain.
