Profile

My scientific background is focused on ruminants with emphasis in digestive physiology, nutrient metabolism and nutritional modelling. I received my PhD in Animal Science from the Autonomous University of Barcelona (Spain), working on rumen targeting strategies to reduce nitrogen excretion from ruminants. Then, I joined the group of Prof Van Amburgh at Cornell University (USA) mainly involved in the update of the Cornell Net Carbohydrate and Protein System (CNCPS).

Research

My research goal is to develop more sophisticated and dynamic models of ruminant nutrition that will advance our understanding of animal functions and nutritional biology. The effective utilization of this knowledge should lead to the development of optimal production strategies, improving the efficiency of livestock production and reducing its environmental impact. Specific interests include:

  • Life Cycle Assessment (LCA) of feeding strategies to reduce environmental impact (nitrogen and methane) of dairy and beef cattle
  • Development of adequate models for grass-fed dairy cows
  • Development of modelling tools to assess the lifetime nitrogen efficiency of dairy cattle
  • Sustainable intensification of forage-based production systems
