My main focus is plant breeding of pea cultivars for western Canada and the northern tier states, as well as research related to improving the pea crop in terms of disease resistance and end-use quality.  I also collaborate on soybean breeding for the short season regions of western Canada.

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.   

• We offer LBGTQ2+ Safe Zone Certification for our lab members
• Our lab is Accessibility-friendly for those with physical disabilities or limitations
• Team members have taken the Bias in Peer Review module and/or the online Status of Women Canada GBA+ training course.
• We follow human resources equity, diversity, and inclusion recruitment practices.
