Tsaiping (Hannah) Liao (she/her)

MSc student

I’m currently pursuing an MSc in Clinical Studies with a specialization in One Health at OVC. My academic journey has led me to a collaboration with Veterinarians Without Borders (VWB). We’re addressing the shortage of veterinary services in Remote Northern Canada, exploring Community Animal Health Workers (CAHWs) and their potential to bridge this gap. We employ qualitative methods like semi-structured interviews and surveys to comprehensively investigate their role in expanding veterinary access. Through this research, we aim to understand the challenges and opportunities of CAHWs in enhancing animal healthcare access in remote Canadian communities. Our goal is to formulate practical, sustainable recommendations that can significantly improve essential animal healthcare services in remote Canadian communities moving forward.


Giselle Kalnins (she/her)

DVM student

My name is Giselle and I am currently a Phase 3 Doctor of Veterinary Medicine (DVM) student at the OVC. I came across the CHPP program while in my undergraduate degree at the University of Guelph and immediately felt at home. Since joining the Van Patter lab in the Fall of 2022, my work has focused on Access to Veterinary Care, as well as Multispecies Justice from a veterinary medical perspective. This past summer of 2023, I assisted Dr. Van Patter with data analysis to see how implementation of the CHPP program in curriculum has impacted new DVM graduates perspectives on spectrum of care in practice. This fall, I will be working on an access to veterinary care project, as well as helping to share our findings from the summer of 2023. Overall, Dr. Van Patter never fails to create a warm, understanding, and inclusive environment in our lab. At home, I live with several four-legged family members and enjoy painting and crafts, as well as spending time camping with my partner and our two dogs in Algonquin Provincial Park.
