Biography

Dr Joehnk joined CSIRO Land and Water as a research scientist in 2010. Before that, he held positions as research scientist at:
+ Leibniz-Institute for Freshwater Ecology and Inland Fisheries, Dept. of Limnology of Stratified Lakes (Berlin/Neuglobsow, Germany)
+ The Aquatic Microbiology Group at the University of Amsterdam, The Netherlands
+ Department of Freshwater Conservation, Brandenburg Technical University of Cottbus, Germany
+ Limnological Institute, University of Konstanz, Germany
+ Institute of Mechanics, Technical University of Darmstadt, Germany
+ Geophysical Institute, Technical University of Karlsruhe (KIT), Germany

Academic qualifications:
Dr.rer. nat. habil., Institute of Mechanics, Technical University of Darmstadt, Germany:
Fluid dynamics, turbulence, dissolved oxygen in lakes

Dr. rer. nat. (PhD), Institute of Mechanics, Technical University of Darmstadt, Germany:

Diploma degree, Geophysical Institute, Technical University of Karlsruhe (KIT), Germany:
Modelling of rotating fluids with focus on the Earth’s outer core

Research areas:
Dr Klaus Joehnk's primary research area is environmental modelling of climate-driven aquatic systems. His special research interests include:
* Continental scale modelling of aquatic systems
* Dynamics of cyanobacteria blooms
* Climate change impact on stratification of lakes
* Mine pit lakes
* Lake ice modelling
* Artificial mixing of lakes
* Nonlinear time-series analysis.

Projects of the last 5 years:
* Development of bloom remote sensing capability and cyanobacteria forecasting model for Western Treatment Plant’s largest treatment lagoon systems (2017-2018)
* Lake Hume blue-green algae risk minimisation (2017)
* Hydrodynamic modelling of aquaculture ponds and reservoirs in northern Australia (2016-2017)
* A national framework for prediction of Harmful Algal Blooms (2015 - 2017)
* Murray River Decision Support System - blackwater, harmful algal blooms (2015-2017)
* Coorong hydrodynamics and macrophyte+fish habitats (2013-2015)
* Western Port Bay sediment transport (2014-2016)
* Wave model and sediment resuspension in the Great Barrier Reef and estuaries (2011-2016)
* Generalized framework for stable isoptope models (2013-14)
* Continental scale groundwater model, AWRA-G (2012-2014)
* Lake model inter-comparison project (LakeMIP)
* Lake ice (GLEON)
* Lake temperature variability on a continental scale

Dr Joehnk is an Associate Editor of the journal Frontiers in Environmental Science - Interdisciplinary Climate Studies
