My research interests are motivated by a commitment to advocate for health, policy, and economic decisions that appropriately reflect individual and population preferences and values. My methodological strengths include areas of epidemiology, health economics (health utility derivation), health technology assessment (systematic review), and choice experiments (discrete choice and best-worst scaling).
Generally, my research has used these methods to inform decisions in pediatric populations. More recently, I have been involved in a the evaluation of transition within the context of nursing curricula, and the measurement of curricular-based outcomes, both topics particularly pertinent to evolving nursing education models in Canada.
An emerging research focus seeks to investigate preferences in vulnerable and sub-populations, such as Indigenous, Arctic, and under-serviced populations.
