Research interests

My primary interest is in statistical modeling in etiologic and predictive research. A focus of my methodological research is objective and reproducible variable selection. Obtaining and communicating easily comprehensible effect size measures to support patients’ decisions on treatment or to support public health recommendations is another research focus of mine. In a former project, I explored weighted estimation in Cox regression as a means to deal with non-proportional hazards, i.e. time-dependent effects, a condition frequently occurring in medical data.

Another main interest is to apply statistical modeling approaches to the investigation of epidemiologic research questions. In the last years I focused on the role of modifiable lifestyle and dietary risk factors on the development of early chronic kidney disease in individuals with type 2 diabetes after 5.5 years of follow-up based on the re-use of data from a large-scale, multicenter clinical trial.

 

What I love about my profession? While as a statistician I can develop new methods and algorithms to learn from the data, as a biostatistician I can apply these methods to extract important patterns and to separate ‘information’ from ‘noise’—in short to make sense of medical data.    

Techniques, methods & infrastructure

For routine application of all new methodological developments software implementations in standard statistical software are made publicly available at http://www.meduniwien.ac.at/user/daniela.dunkler/software.html and http://cemsiis.meduniwien.ac.at/kb/wf/software/statistische-software/.

Two risk prediction models for incidence or progression of chronic kidney disease are also publicly available at http://www.meduniwien.ac.at/nephrogene/data/riskcalc/renal_v4/renal.html.
