Research Interests

I am an ecologist using mathematical modeling to study the structure and dynamics of biological systems. Today, I am working as a PhD student in the SPABIO Lab with Uno Wennergren as my supervisor.

Ecosystems are under a large amount of pressure today. Global problems such as warming, extreme weather conditions and fragmentation are being observed. Models based on knowledge gained from empirical studies help us understand system processes and make predictions. They enable simulations of important scenarios and investigations of effect of events such as climate change and habitat loss.

In my research, I investigate how species interactions and population stability (1/CV) are affected by positively autocorrelated (red noise) environmental variation.

Current Scientific Projects

  • The dynamic rate of food webs alter species response to environmental variability
  • Stability patterns of metacommunities in colored environments
  • Periodic food webs enable an infinite number of interacting species
