Pozniak joined the University of Saskatchewan (USask) in 2003, quickly advancing through the university tenure system from associate professor in 2009 and full professor in 2014. He leads the Durum and High -Yield Breeding and Genetics program as the Ministry of Agriculture Strategic Research Program (SRP) Chair and is currently the Director of the Crop Development Centre.
Pozniak is the author of three book chapters relating to wheat development and genetics, and 118 refereed journal publications. He has bred or co-bred 23 durum and high yielding wheat varieties and has supervised or co-supervised over 40 graduate students, many who continue to be leaders in the agriculture sector.
Pozniak’ s contributions to the agriculture industry have not gone unnoticed. He was the co-lead scientist on the consortium of international researchers that decoded the genome sequence of wheat. This multi-year project provided the necessary tools needed by wheat breeders to accelerate wheat variety development. In 2019 he was awarded an Outstanding Leadership Award by the International Wheat Genome Sequencing Consortium for his leadership during the project, and in 2014 was presented an Award of Innovation by the Saskatoon Achievement in Business Excellence (SABEX).
