About Me
Hi! I'm Ema, and I study how global change affects the connectivity among ecosystems via resource flows (resource subsidies), with cascading effects on ecosystem function and biodiversity. My research focuses on two dimensions of global change: changes in ecosytem size and rise in cyanobacterial blooms. I'm currently a postdoc at the University of Copenhagen in the Freshwater Biology Section working with Jana Isanta-Navarro and Kirsten Seestern Christoffersen in Denmark. I recently (October 2025) graduated my PhD with Florian Altermatt at the Swiss Federal Institute of Aquatic Science and Technology (Eawag, ETH domain) and the University of Zürich in Switzerland.
