When a supposedly healthy infant passes away, it can be hard to understand why. Juan Lavista Ferres (Microsoft), Dr Jan-Marino Ramirez and Dr Tatiana Anderson (both from Seattle Children’s Research Institute), and Professor Edwin Mitchell (University of Auckland), form the core of a novel collaboration to conduct vital and extensive research into the risk factors and mechanisms behind sudden unexpected infant death. This unique collaboration spanning across disciplines, industries and continents, is providing the deeper understanding that is needed to prevent unnecessary infant deaths.
