Child Health Evaluative Sciences

Who we are

The Child Health Evaluative Sciences (CHES) program consists of a multidisciplinary group of researchers within the SickKids Research Institute united with a common aim: to improve the welfare of children by enabling health care decisions to be based on the best possible evidence generated through the integration of research, clinical practice and training, and the development and application of the most effective research methods. CHES scientists accomplish this through the integration of research with clinical practice and the development and application of advanced research methods.

Our Mission

To be a premier research program in the design, conduct, and dissemination of highly impactful research, and to translate findings into clinical practice and health care policy so that paediatric health care delivery and the quality of life of children and their families is improved.

Our Values

Excellence: demonstrated by the quality and thoroughness of our work
Compassion: focusing on individual patients’ and families’ challenges and needs
Integrity: articulated through transparency and reproducibility of our work
Collaboration: through wide-reaching and effective partnerships, locally, nationally, and internationally
Innovation: bringing novel solutions to health care evidence gaps
