I am a Post-Doctoral Fellow with expertise in observational research and meta-analysis. My research aims to improve the treatment of substance use disorders, focusing on opioid use disorder treatment. During my PhD candidature, I conducted a mix of high-quality systematic reviews, analysis of prospective cohort data, and linkage of administrative data to examine experiences of childhood trauma and comorbid mental disorders among people with opioid use disorder. I have experience in longitudinal data analysis of data from people who primarily use heroin and those prescribed opioids for chronic pain. I have collaborated with international research groups across several projects, including seven systematic reviews and meta-analyses. To date, I have contributed as an author to nineteen articles, including seven first-author peer-reviewed publications and one technical report.
