Research

Gill’s research program focuses on improving the evidence-base for children hospitalized in general paediatric settings, particularly for conditions which have important long-term impacts and that cumulatively lead to a significant burden on the health-care system.

His overarching methodological expertise is in clinical epidemiology and qualitative research, where he focuses on conducting outcome-based research. Gill also co-founded the Canadian Paediatric Inpatient Research Network (PIRN), a hospital-based network to which aims to conduct multi-centre studies to answer clinically important questions to improve the outcomes for hospitalized children.
