Research Interests:

I am a fluvial biogeochemist interested in understanding the role of hydrological extreme episodes, such as floods and droughts, in the carbon cycling in inland waters.  I am mainly specialised in the study of dissolved organic matter as a key component of the carbon cycle. I am especially interested in better understanding the controls that hydrology has on the quality and quantity of dissolved organic matter, which ultimately determines its interactivity with the environment and, hence, within the carbon cycle.

My research interests are also focused on statistical methods that can enhance the data mining from complex data sets on dissolved organic matter quality, such as exctitation-emission matrix data sets.


I am currently working as a post-doctoral scientist in Wasser Cluster Lunz.
