Research Interests:

Dr. Lo’s specific research interests include community nutrition, program planning and evaluation, food environment, food choice, rural health, immigrants’ health, postdoctoral fellows’ health, mental and psychological health, obesity prevention, physical activity, parenting, fatherhood and health equity.


Dr. Lo is an assistant professor in the Department of Family Relations & Applied Nutrition at the University of Guelph. He completed a bachelor of applied science degree in nutrition and food at Toronto Metropolitan University (2011) and a master of public health degree in community nutrition at the University of Toronto (2013). After serving as an independent research consultant for Toronto Public Health, Dr. Lo completed a PhD in community nutrition at Cornell University (2019) in Ithaca, New York, and a postdoctoral training program at Boston College School of Social Work (2022) in Boston, Massachusetts.

Dr. Lo’s research focuses on improving the health of underserved populations, including rural residents, fathers, immigrants and postdoctoral fellows. He is particularly interested in exploring determinants of weight-related behaviours (e.g. nutrition, physical activity, mental and psychological health and sleep) in different social, cultural and environmental contexts. He uses various methods (e.g. surveys, longitudinal cohort studies, interventions, scoping reviews, interviews and focus groups) to plan, manage and evaluate relevant health-enhancing strategies, and he employs community engagement and capacity-building approaches to conduct his research.

As a nutrition and health researcher, Dr. Lo conducts impact-oriented research that addresses social, cultural and environmental influences on food choices and other weight-related behaviours among underserved populations. Dr. Lo began his research career by working as an independent research consultant for Toronto Public Health. In this role, he developed the Toronto Nutrition Environment Measures Survey-Store (ToNEMS-S), a retail food environment assessment tool, which has been widely used by academic institutions, public health agencies and local food organizations to monitor the healthfulness of the retail food environments in their jurisdictions. For his doctoral work at Cornell University, he received various grants and awards to examine the weight, diet, physical activity and social impacts of a multilevel weight loss intervention that targeted rural women in Montana and upstate New York who were overweight or obese. During his postdoctoral training at Boston College School of Social Work, he examined the trajectory of fathers’ weight and weight-related behaviours (e.g. diet, physical activity and sleep) and how their engagement with their children influenced those behaviours from prebirth to two years after birth. At the University of Guelph, Dr. Lo’s projects focus on the following:

1)           The impacts of parenthood on fathers’ diets and health

2)           Fathers’ roles in their children’s diets and childhood obesity prevention

3)           Stress interventions targeting immigrant parents

4)           Postdoctoral fellows’ physical and psychological health
