Curriculum Vitae

Born in Čakovec, Croatia. He is a professor at Department of Geology and Geological Engineering, Faculty of Mining, Geology and Petroleum Engineering, University of Zagreb. He received award from Croatian Waters for best Graduate Thesis in Area of Water Management and award for the best PhD Thesis. He attended different courses in England, Germany, Switzerland and Czech Republic where he participated in modeling of reactive transport in ground water and site characterization for geological repositories in sediments and hard rocks.

Main Research Activities

·          Near future research is focused on field experiments for assessing the anisotropy of hydraulic conductivity of the unconfined heterogeneous alluvial aquifers in collaboration with Dr. Vinko Jović, Full Professor at the Faculty of Civil Engineering, Architecture and Geodesy, University of Split.


·          From 2012 until present, I have been modeling the impact of weirs and hydropowerplant pools on groundwater levels of the unconfined heterogeneous alluvial aquifers using finite element method (seepage from hydropowerplant pool’s into the drainage systems and hinterland) and finite difference method (regional groundwater flow and contaminant transport modeling).


·          During the year 2010 and 2011 I have designed and conducted artificial tracer experiment in unconfined heterogeneous alluvial aquifer with highly transient flow conditions (http://www.bioforsk.no/ikbViewer/Content/97809/D2_2_annex_final.pdf). Further geophysical research have been conducted in year 2012.


·          In the period from 2009 until 2011, I have developed an objective-based method and a software for analyzing groundwater quality data primarily applicable to large databases. The method and the software mimics subjective appraisal of the graphical presentation of groundwater quality changes in time using five objective-based criterions and extends the analysis in space, in order to assess objective chemical state of groundwater.
