DR. MARTIN STEPPAN · RESEARCH & METHODS
Contributions to addiction and behavioural epidemiology: digital data sources, health services research, privacy-compliant data linkage and population estimation.
DIGITAL EPIDEMIOLOGY · 2013
Comparison of Google search volume indices with survey data on cannabis use across countries and regions. Search data complement established sources; alone, they are insufficient for robust prevalence estimates.

RESEARCH SOFTWARE
A web-based calculator for estimating population sizes from multiple, partially overlapping data sources. A tool for epidemiological analyses of incompletely observed populations.
Open calculatorDocumented expert contributions at the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), now the EUDA:
Comparison across Germany, the Netherlands and the United Kingdom exploring increasing demand for cannabis treatment.
Presentation of the German addiction treatment statistics and facility survey within the German care system.
Presentation of my estimation approach and leadership of a methods workshop, plus a contribution on relative incidence estimation.
Pharmacy as a minor subject, with completed coursework in hygiene and microbiology. My work also includes bioinformatics approaches in statistical genomics, particularly GWAS, SNP data and genetically informed epidemiological analyses.
