Research Focus

Avian Diseases and Poultry Production: Before finishing my DVM I realized that avian diseases and poultry production were my areas of interest, so I decided to educate myself in those areas as a volunteer in several diagnostic laboratories and poultry companies. This preparation included one semester as an exchange student at Washington State University where I did rotations in their avian diagnostic laboratory. During my DVM thesis I worked characterizing immune responses in ostriches again Newcastle disease virus, integrating all my previously acquired skills in avian diseases and poultry production. After obtaining my veterinary professional degree in 2004 I worked as a unit veterinarian in a Hy-Line layer and layer breeder company located in Chile where I was able to learn all the different tasks related to layer and layer breeder production including administration and avian health. In 2007 I moved to the US looking for experience in avian disease investigation. During my PhD I have studied very important and prevalent diseases of the poultry industry focusing especially in infectious bronchitis virus. Currently I am finishing my PhD (December 2011).

Specialty Focus

My research interests are in the area of the avian virology, specifically in RNA viruses and their capabilities of mutation, recombination and variation making them very difficult to control in productive settings. I enjoy applying the information gathered in the laboratory by molecular or virological techniques in the field improving productive parameters and performance of poultry flocks. I also have a special interest in vaccine design for poultry.
