Title Position: Assistant Research Professor

Department: Hubert Department of Global Health

Past Work in Hispanic/Latino Health:

Latin America: Dr. Vidal has conducted studies in rural Peru with two different research groups and South Mexico (Chiapas) and Sinaloa, a State located at Northwest, Mexico.

Current Work in Hispanic/Latino Health:

Projects: Studies in Peru continue evaluating the burden of pneumococcal carriage in rural communities. Carriage of other important pathogens are also studied by Dr. Vidal's group in Peru. The impact of the introduction of the pneumococcal vaccine in carriage of vaccine serotypes, pneumococcal diseases and antibiotic resistance of strains isolated post vaccination is also investigated in different regions. Studies in Chiapas Mexico are focused on gastrointestinal diseases caused by bacterial pathogens and parasites in highly marginalized populations. Burden of gastrointestinal diseases, mortality and etiology of those diseases are a primary research focus in Chiapas, Mexico. Intervention studios have also been conducted trying to design devices to reduce the number of pathogens in water sources, which to this population is mainly taken from rivers, wells, and other potentially contaminated sources. Research in Sinaloa, Mexico is focused in evaluating the role of strains of V. parahaemolyticus in gastrointestinal diseases. We are also monitoring, using molecular technology, the spread of pandemic strains of V. parahaemolyticus, serotype O3:K6, in North Mexico. With our collaborators in the University of Sinaloa School of Medicine, we began investigating the burden of respiratory diseases caused by bacterial respiratory pathogens as well as the activity of immune proteins against S. pneumoniae strains isolated in this region.

Opportunities for Students:

Dr. Vidal has mentored students on theses and research conducted in Latin America. In the past, he has assisted Masters of Public Health students with such projects. Dr. Vidal encourages students to get involved with faculty research and has supervised student work. Previously, undergraduates have conducted general laboratory work and graduate students have worked on thesis projects in addition to defining laboratory protocols and investigating sources of gastrointestinal diseases in the south, and Northwest, of Mexico.
