Dirk Erler’s research is broadly divided along two lines: understanding aquatic nutrient cycling in natural systems, and developing strategies to improve nutrient/energy recovery in engineered systems.


Dirk's pure research involves understanding nutrient cycling processes in natural and engineered systems, including: use of stable isotopes to quantify novel N cycling pathways, understanding greenhouse gas dynamics, and using stable isotopes for paleobiogeochemical reconstructions. His applied resarch focusses on finding solutions to industry related nutrient and aquatic pollution issues which builds on concepts of sustainability and the circular economy.
