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 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.
