My research is in parameter estimation, sensitivity analysis and uncertainty analysis of complex models. I am focusing on the application of derivative-free optimization methods for model calibration as well as the usage of sensitivity information during calibration and model development. In the course of my research I applied these methods in different fields like biomechanical systems, cellular processes, Systems Biology, as well as hydrologic and land-surface models. I am further strongly interested in the development of robust and widely applicable computer codes. I have experience in managing large computer codes/ projects, like the hydrologic model mHM, the hydrologic framework Raven and a Fortran library. Besides model analyses and code development I have made major contributions in the field of Big Data management through the development and implementation of the Canadian Surface Prediction Archive CaSPAr. This archive is storing and handling 8.5TB of incoming forecast data per month and aiming to provide them to the wide public through a web-based interface.

Current Research Topics

  • Development of the Canadian Surface Prediction Archive (CaSPAr)
  • Development of frugal sensitivity analysis quality checks
  • Development of multi-objective sensitivity analyses
  • Parameter screening and sensitivity analyses of hydrologic models
  • Calibration and uncertainty estimation of hydrologic models
  • Multi-objective calibration of complex models

CaSPAr is online!

Since June 2018, the Canadian Surface Prediction Archive CaSPAr is online and operational. You can now request numerical weather predictions issued by Environment and Climate Change Canada. Eight different products are available. You can subset them by selecting time periods, forecast horizons, your domain of interest, and the variables you need and therefore reduce significantly the amount of data you have to handle. All data are in CF-1.6 standradized NetCDF format. Enjoy! Read more...
