I supported healthcare, life sciences, pharmaceutical, and HEOR studies from design through final reporting. At the Centre for Nursing Research, Jewish General Hospital, I reviewed protocols and consulted with principal investigators and graduate students on study methods and Statistical Analysis Plans. My work also included systematic reviews, meta-analyses, and statistical methods and results sections for peer-reviewed publications. During my biostatistics internship at Lady Davis Institute, Jewish General Hospital, I studied GLP-1 agonists and mortality among breast cancer patients with type 2 diabetes, applying a prevalent new-user design to address immortal time bias. I hold an M.Sc. in Statistics (Biostatistics) from Université de Montréal and have authored seven peer-reviewed publications. ``` ## Experience ### Research Professional Analysis Group.
