Equity, Diversity and Inclusion

As reflected in the University of Saskatchewan (USask) Mission, Vision and Values, the institution is committed to diversity, inclusion, and equity in the workplace and believes that our workforce should reflect the diversity of our students and community. Awareness of these intrinsic values is actively promoted at all levels of the university, including by the President and senior leadership.

Present in our laboratory environment and thus our project team composition is a deep respect and awareness of the value and contribution of equity, diversity and inclusion. When assembling our research teams we strive to overcome inherent bias present in the workplace and overcome any potential barriers to inclusion by considering all qualified individuals, including women, Indigenous Peoples, persons with disabilities, members of visible minority/racialized groups and members of LGBTQ2+ communities. Inequalities with age, education, parental status/responsibility, immigration status, religion, language, place of origin, ethnicity, culture, and socio-economic status are also taken into consideration.  The pulse crop breeding team at the University of Saskatchewan is diverse; within our team are people who were born in many countries and of this team ~40% are women.
