In biostatistics, the real measure of good work is not the journal’s impact factor or the size of the grant, but whether the analysis is honest, the methods are fit for purpose, and the findings can be trusted to guide decisions. Dr Darssan aims to do this kind of work: careful, transparent, and selective within focused teams of like-minded colleagues where statistical thinking is shared rather than outsourced. The goal remains constant: better evidence that ultimately advances modelling of geographical patterns and environmental impacts.

His research centres on applying and extending statistical methods, particularly spatial and environmental approaches, to address practical problems in complex observational and environmental data. He remains committed to transparent, reproducible practice and to mentoring the next generation of applied spatial and environmental modellers.

Dr Darssan values teaching that builds genuine statistical confidence rather than surface-level competence. His approach centres on active learning, real-world data, and creating an environment that encourages students to ask questions, challenge ideas, and think critically. He uses R-based workshops, practical case studies, and structured discussion to develop computational skill, logical reasoning, and critical judgement. As a Fellow of the Higher Education Academy (FHEA), he remains committed to reflective, student-centred practice that prepares learners to use statistics thoughtfully in their future work. He has taught approximately 1,300 postgraduate and 1,000 undergraduate students in foundational and applied statistics, and has supervised 9 Master’s dissertations and 8 PhD students to completion.

He values service as service, not as a means of promotion or personal return, but as a genuine commitment to helping others. Externally, he contributed as Statistics Editor for Clinical Toxicology, Associate Editor for Archives of Environmental and Occupational Health, President of the Statistical Society of Australia – Queensland Branch, Webinar Coordinator for the Teaching of Statistics in the Health Sciences section of the American Statistical Association, and Social Media Editor for the Australian and New Zealand Journal of Statistics. He also regularly reviews manuscripts and examines research theses.

Within the University, he has served as Program Director of the Bachelor of Health Sciences, co-founder of the Environmental Epidemiology Research Group, Engagement Coordinator for current students, PhD progress review chair and thesis examiner. He also developed the School’s LinkedIn presence. He particularly values conversations with like-minded people who undertake service for its own sake, rather than for personal benefit.

As a service statistician, Dr Darssan has spent years supporting investigator-initiated clinical trials, contributing to study design, randomisation, protocol development, statistical analysis plans, final reports, and data safety monitoring. He has provided statistical expertise to clinicians and researchers across ophthalmology, nephrology, rheumatology, endocrinology, and health services research.

Dr Darsy Darssan is a Senior Lecturer in Biostatistics at The University of Queensland’s School of Public Health. He holds three degrees in Statistics from mathematical sciences schools: a BSc (Hons) from the University of Jaffna (2005), an MAppSc from RMIT University (2008), and a PhD from Queensland University of Technology (2014). His early career included roles at the Australian Council for Educational Research, the University of New South Wales, and the University of Wollongong, followed by postdoctoral research in biostatistics at the University of Liverpool, UK. He returned to Australia in late 2015 and has been at UQ ever since.

Do good by stealth, and blush to find it fame.

Dr Ben Tscharke is an analytical chemist with a keen interest in quantifying analytes in environmental samples. Ben is currently a Senior Research Fellow at the University of Queensland research institute, Queensland Alliance for Environmental Health Sciences (QAEHS), joining in February 2017 after graduating his PhD from the University of South Australia the previous year. His key focus at QAEHS involves the wastewater based epidemiological approach to determine community consumption and exposure to a range of illicit drugs, pharmaceuticals and personal care products. He leads the Australian Criminal Intelligence Commission's National Wastewater Drug Monitoring program at UQ, which collaborates with the University of South Australia (https://www.acic.gov.au/publications/intelligence-products/national-wastewater-drug-monitoring-program-report).
