Michael Zoratti is currently pursuing his PhD in health research methodology at McMaster University. Through his prior studies at McMaster (MSc) and work experience in the pharmaceutical consulting industry, Michael has specialized in the field of health technology assessment, with training in biostatistics, the critical appraisal of clinical and health economic literature, the development of health economic models, and the methods of systematic literature reviews. He has experience applying these research methods to a number of clinical areas, including mental health, rheumatology, diabetes, and oncology. His research interests center around the development of health economic evaluation methodologies, including the use of network meta-analysis to inform comparative clinical outcome estimates and the application of health preference measures to health states in cost-utility analyses.

Kevin Kennedy is pursuing a Ph.D. in the Health Research Methodology program at McMaster University. He began his studies in Psychology at Carleton University while working for the Public Service Commission as an analyst. He made the full time commitment to research in pursuit of his Master’s degree in Experimental Psychology at Laurentian University. For his Master’s, he studied regression techniques and psychometric validation, where he explored how clinical psychologists utilised decision support systems when making decisions on correctional officer candidates for their psychological suitability. Currently, Kevin is continuing work in psychometrics for applications in health care, establishing the psychometric validity of a disease-specific preference-based measures of health related quality of life for glaucoma (HUG-5). His doctoral research reviews common economic preference elicitation techniques (standard gamble, time trade-off), and contrasts utility functions with Louviere’s Best-Worst Scaling technique for disease-specific and generic measures of health related quality of life.
