My research program aims to conduct interdisciplinary systems-based research to improve the resilience, sustainability and profitability of grain production in Western Canada and semi-arid environments in general. Through collaborations with the existing expertise present at the University of Saskatchewan, as well as engagement with grain producers, my program aims to take a broad look at how agronomic practices can be developed or adapted to address sustainability issues. I am particularly interested in testing new systems, for example, cover crops, intercropping, re-integrating livestock with grain cropping, and winter broadleaf cultivation, among others. I am also trained as a crop physiologist, and I am interested in investigating drought adaptive traits, with an emphasis on improving water use efficiency in pulses.
