This study examines whether opening new medical residency programs improves health outcomes. Comparing counties with and without new residency programs, the research found that mortality rates fall by 4.8% where programs are introduced. However, similar benefits were not observed in rural areas, highlighting the importance of healthcare infrastructure and training location.

This research reconstructs viral transmission trees using genomic sequencing data to study how human behavior shapes infectious disease outbreaks. Analyzing COVID-19 transmission in Iceland revealed differences in infectiousness across quarantined and demographic groups, informing vaccine distribution strategies that improved population-level protection and influenced national public health policy.

This research uses wastewater-based epidemiology to monitor antibodies excreted by communities, providing early insights into population vulnerability to infectious diseases. By analyzing antibody trends in wastewater over time, the work helps public health authorities identify at-risk communities, allocate resources more effectively, strengthen vaccination strategies, and improve outbreak preparedness.

This research uses linked provincial health data to measure the population burden of coeliac disease in Alberta. By identifying diagnosis rates, care gaps, and early-life risk factors, the work informs healthcare planning and policy. The findings highlight rising diagnoses in children and the long-term personal and economic impact of a lifelong, diet-based condition.

This research evaluates electronic case reporting (ECR), an automated disease surveillance system that alerts public health agencies as soon as diagnoses are recorded. By analyzing surveillance data and clinician experiences, the work aims to improve outbreak detection speed, accuracy, and usability—helping public health respond earlier and save lives.
