Catherine L. Mah MD PhD is Professor and Canada Research Chair at Dalhousie University, recipient of a Queen Elizabeth II Platinum Jubilee Medal for public service.

I am a professor at Dalhousie University, most widely known for my scientific work in nutrition and food insecurity policy. My lab has been recently occupied with questions about food affordability: inequities in food pricing, drivers of purchasing substitutions, cost of a healthy diet. My goal is to inform the design of policies comprising a stronger social safety net for Canada, as well as indicators used for routine governmental decision-making. In addition I am doing some theoretical work on social and material relations around food affordability in consumer society. Although I have been working for many years as a scientist and in randomized controlled trials, my first education was in conservatory performing arts. I have found ways for interpretation to exist happily alongside analysis in my scholarly work.

My latest project grant from the Canadian Institutes of Health Research (2023-2028) partners with Nova Scotia’s provincial health authority to examine how workplace food pricing shapes health workers’ purchases and diet quality. The study is made possible through methodological and infrastructural developments in nutrition using person-level longitudinal purchasing data. Don’t @ me as a methodological individualist! Since graduate school I have had an enduring concern with how the collective (and institutional, common, solidarities, universal etc.) exists in contingent relation to the individual (personalisation, difference, targeting, particular etc.) in explanation and ontology for health and social policy. An abstraction? No: while completing my PhD, I practised as a community paediatrician for seven years. My doctoral thesis, Governing Immunization in Canada, examined evolving personalisation within the Canadian public health regulatory framework, federal-provincial-territorial relations, and novel vaccine programs.

Thinking about the fate of pluralism keeps me up at night—really, I have awful insomnia. My latest favourites for taming the grey matter are short stories in translation. When I am not working you can usually find me elbows deep in bread dough and a book. Here is a list of what I was reading last winter (scroll to the bottom) for Freedom to Read Week.
