Who We Are

Katie Pullella


Katherine Pullella

Hi everyone! My name is Katie Pullella and I’m excited to be the President for the 2022-23 NSGSA. My primary goal is to create a strong sense of community among all DNS graduate students and will work to ensure all students remain well-connected to each other and have access to the appropriate resources and support throughout the year! Our team is inspired, engaged and ready to get to know you all! 

A little bit about me - I’m a senior Ph.D. candidate, supervised by Dr. Joanne Kotsopoulos at Women’s College Hospital. My research examines the impact of dietary and environmental exposure to heavy metals, such as arsenic, on cancer risk in Canada. In addition to my role on the NSGSA, I’m also one of the editors of Nutrizine, our graduate-student-led department magazine. In my free time, I love to get outside and explore different areas in Toronto, cycle, read and catch up with friends!

I hope to get to know all of you better and meet you at one of our events soon! Please don’t hesitate to reach out if you have any questions/ comments or concerns.

Sarah Jarvis

Hi everyone! I’m Sarah and I am excited to be this year’s NSGSA Vice-President. This year I am dedicated to building the academic and professional skills-related programming on behalf of the NSGSA. 

I am a PhD student working under the co-supervision of Dr. Vasanti Malik and Dr. David Jenkins. My research integrates nutrition and environmental impacts to study sustainable dietary patterns and cardiometabolic health outcomes. I am developing a database and multidimensional index of foods in Canada to model and analyze dietary patterns and am also implementing a nutrition education program among youth. Outside of my research, a few of my favourite things include cooking with friends, getting outside for a bike ride/run, and any activities on the water or in the snow!

I look forward to meeting everyone at our events throughout the year! If you have any suggestions/questions/ideas you want to chat about, please do not hesitate to reach out.
