Overview

A/Prof Janni Leung (PhD) is an NHMRC Development Fellow at National Centre for Youth Substance Use Research (NCYSUR) at The University of Queensland. Their program of research includes investigating the epidemiology of substance use and mental health because they are both major public health issues that commonly occur together. This research program had made paradigm-changing development through 100+ articles, which have recognised impact (15,000+ cites, 30% output in the top 1% citation percentile). Many of their work involves conducting systematic reviews, meta-analyses, and applying statistical models to epidemiological data on addiction and mental health issues to better understand their impacts on populations. Her work is used to inform policies on how to reduce the disease burden caused by addiction and mental health problems in Australia and overseas. Janni is committed to conducting high-quality rigorous research to generate empirical epidemiological evidence to inform decisions to prevent addiction-related harms in the population.

Teaching and supervision: They have qualifications and training in public health, sociology, and psychology. In addition, they have strong research and teaching experience in epidemiology and biostatistics. Janni has worked with a range of students from diverse demographic and cultural backgrounds, including mature-aged students and students with family responsibilities. She currently has a topic available for a self-motivated student interested in addiction research. Janni’s current research focus is on the epidemiology and disease burden associated with mental and substance use disorders across the globe.

Consultation: Janni is available for private consultation and workshop presentations on request for various research methodological and statistical topics, e.g. systematic reviews and meta-analysis, questionnaire and survey designs, cross-sectional and longitudinal analyses.

Where can you find Janni: Janni is based at the UQ St Lucia campus with regular visits to the Long Pocket and Herston campuses. You may also catch Janni at the APSAD conference.
