I’m a marine scientist specialising in the study of effects of climate warming and other human-induced stressors in marine, coastal and freshwater ecosystems, with over 13 years of experience (including doctoral research). I apply diverse modelling approaches (ranging from 0D to 3D models) to understand how aquatic food webs respond to anthropogenic perturbations, linking organism-level responses to ecosystem functions such as biological production and carbon export. Additionally, I apply coupled model systems to predict future changes in oceanic biological states, and analyse ensemble runs to investigate consequences of climate overshoot. I’m also interested in data assimilation approaches to ecosystem modelling. 
My specific research interests are as following:
  1. Trait-based approaches to phytoplankton and zooplankton dynamics
  2. Stressor interactions and cascading effects in marine and lake ecosystems
  3. Carbon export and particle dynamics 
  4. Virus – phytoplankton dynamics
  5.  Marine pollution
  6. Climate overshoot simulations
I believe aquatic ecology and socio-economics are tightly coupled, and therefore I’m equally interested in studying how changes in our water bodies affect human society and local & global economy. I always encourage and welcome a broader participation in scientific research as my core philosophy is “world is one family”.
