Prizes and Awards

  • Massey University Research Medal for Individual Research Supervisor in 2015. In 2015 I was awarded the the Massey University Research Medal as Individual Research Supervisor for my work over the past 17 years, working at Massey’s Institute of Veterinary, Animal and Biomedical Sciences, The main statement of this award was "Professor Nicolas Lopez-Villalobos has supervised 66 postgraduate students and been chief supervisor of seven doctoral and eight master’s students. For virtually all of them, he was an important adviser on trial design and statistical analysis and his support has been essential to their success. His great strength lies in the application of statistics to animal breeding, production and health. The high quality of his work and advice is reflected in the number of publications in high impact journals, where the statistical analysis is a very rigorous process. Professor Lopez-Villalobos has been awarded nearly $6 million in research grants, and has been very successful in obtaining scholarships for graduates, including three granted by the Irish Government, showing how his scientific and supervisory skills are highly regarded on the global stage." - Massey University Research Medal (2015)
