[7] Hay has remained at the University of Oxford where he is now a member of congregation and was awarded the title of Reader (2008) and then Professor (2012).
[2] In 2012 he also became a Research Fellow in the Sciences and Mathematics[8] at St John's College, Oxford where he gained a higher doctorate (D.Sc., 2014).
Hay's future goal is to create high spatial resolution maps for all the diseases, risks, and injuries covered by the GBD, which could be possible in the next 10 years with advances in technology.
Influential colleagues in the field, Peter Hotez[10] and Jeremy Farrar[11] acknowledge Prof. Hay's geospatial vision in presenting complex data sets in an accessible way that has led to policy changes worldwide.
Kofi Annan[12] recognised the importance of Hay's recent work in his article,[13] saying, “Such fine-grained insight brings tremendous responsibility to act.” Published in Nature (journal), these high-resolution maps of child growth failure (stunted growth, wasting and underweight),[14] and educational attainment,[15] clearly illustrate local progress made during the Millennium Development Goal era, as well as, some entrenched inequalities across the continent, that need significant attention in the Sustainable Development Goal era.
