Research Interests:

- Helicobacter pylori infections in children and adults. When I was working at the National Cancer Institute in Mexico, I started studying the acute and chronic effects of Helicobacter pylori infection in adults. Together with Stanford University and a group in Chiapas State in Mexico, we did a case control trial to see if eradiaction of H. pylori decreased the amount of preneoplastic lesions. My interest has expanded to the study of this infection in children and I am currently involved in several projects in this population.
- Emerging and Re-emerging infections Upon arriving at the Centers for Disease Control and Prevention (CDC), I was integrally involved in high-prorfile outbreak investigations of emerging and re-emerging infectious diseases. The CDC pathology team has developed a variety of immunohistochemical and molecular assays to detect these patholgens. Detection of microbial antigens by immunohsitochemical methos in tissues has to be correlated with other laboratory tests. The combination of tissue and laboratory diagnosis of infectious agents is of vital importance to detect these emerging and re-emerging infections so that public health authorities place control and prevention measures.
- Education Since starting at Emory in 2009, I realized that there was a need to have curriculum content in certain areas that could be accessed at all times by trainees. To accomplish this, an Emory innovation grant in teaching was obtained allowing the creation of the Emory Pathology eLearning Portal. The modules present in this website have been tested and multiple publications have occurred using the material present in the modules.
