Career

I graduated from my BSc. Agriculture Sciences in 2005 from the Escuela Agrícola Panamericana  ‘Zamorano’, Honduras. I continued with my MSc studies under the Erasmus Mundus programme in the European Master in Animal Breeding and Genetics at the Universität für Bodenkultur, Vienna, Austria, and at AgroParisTech, Paris, France, resulting in the achievement of 2 MSc degrees in 2009. Additionally, I conducted my MSc thesis project at the INRA Jouy-en-Josas, France, estimating correlative responses on sow reproduction in a selection experiment for residual feed intake. I completed my PhD degree in Agriculture and Food Science with a focus on sow welfare and behaviour from University College Dublin, Ireland in 2014, but as a recipient of a Teagasc Walsh Fellowship, I was based at Teagasc Moorepark, Fermoy.

From October 2013 to October 2015, I worked as a postdoctoral research associate at the Department of Animal Science at the Iowa State University in the U.S. National Pork Board “Sow Lifetime Productivity” project focusing on improving sow longevity through feeding practices during the gilt developmental period. I am currently working as a postdoctoral research fellow at the Pig Development Teagasc, Fermoy, working mainly on a project regarding risk factors for respiratory diseases in growing-finishing pigs and developing a budgetary simulation model for the Irish pig production.

I completed a professional certificate in Bioinformatics from University College Dublin in 2017.
