Dr. Grace Marquis- Associate Professor at McGill University Grace S. Marquis is Associate Professor at McGill University and Associate Professor/Collaborator at Iowa State University. Her research career began in Peru at the Instituto de Investigación Nutricional. In 1999, her research group started working in Ghana. These long-term collaborations continue today. The work in Ghana is primarily through the Nutrition Research and Training Centre, a permanent research site which she built in the Eastern Region in collaboration with faculty at the University of Ghana. Her community-based research examines how many social, cultural, biological, and environmental factors interact and the mechanisms by which they alter a household’s ability to provide optimal feeding and caregiving for young children. Based on acquired knowledge, her research group develops alternative strategies that will support child health and growth and are feasible for families in poverty. Dr. Marquis is Associate Editor for Advances in Nutrition. She was the Canadian Research Chair in Social and Environmental Aspects of Nutrition from 2006-2016. She received a Doctorate of Laws, honoris causa, for contribution to tertiary education from the University of Ghana in 2013.

Meray Arnouk, MSc Student

Meray ArnoukMeray received her Bachelor’s degree in pharmacology in her home country of Syria. Her work as an NGO-affiliated health educator in refugee camps showed her the importance of the social determinants of health for proper nutrition and disease prevention. Passionate about humanitarian work, she pursued a Master’s in nutrition at McGill University with a focus on global nutrition. Her research was unique; a mixed methods study that focused on the determinants and consequences of overweight and obesity in rural Ghanaian farmer households. During her one-month stay at the Nutrition Research and Training Centre in Ghana, she carried out a qualitative study with the help of LinkINg Up project communities. The study highlighted the importance of considering context and local people’s perceptions when designing research methodology and thinking of solutions for nutritional problems. Learning from the LinkINg UP project, Meray understood how research can be transformative and life-changing when i) it takes into account the population’s economic and lifestyle priorities, and ii) it is designed in a way that is sustainable. Upon returning to Canada, Meray presented her research findings during McGill's 2021 Global Health Week. Meray received her  Master’s degree in February 2023 and is eager to work in the humanitarian sector and help improve the well-being of vulnerable groups.
