On August 3rd I started my position as a Earth Research Scientist at the Earth & Environmental Sciences Area of the Lawrence Berkeley National Laboratory. I will be working in the DOE-funded Watershed Function Project where we are investigating "how complex, multi-scale interactions can lead to a cascade of downstream effects on water availability, nutrient and metal loading, and carbon cycling" (Susan Hubbard, Watershed Function Project Lead). The study site of the project is located in the upper Colorado River with focus on the East River catchment. I am looking forward to be working with the interdisciplinary research group working on the Watershed Function Scientific Focus Area.

I wrote a blog post for the EGU HS blog  that you can read here: https://blogs.egu.eu/divisions/hs/2019/05/22/everything-is-interaction-and-reciprocal/ and below is a list of literature on which this post was partly based and could provide further reading for the interested among you:
