I am a quantitative ecologist working at the interface between ecology, computer science and physics, trying to unravel the mechanisms regulating species interactions and stability of complex natural systems against the backdrop of Global Change.

My main research interests are biodiversity, macroecology and global change. I am interested in biodiversity synthesis and biodiversity patterns, and how we can generalize information across taxa and habitats, and furthermore across scales. In my future research, I will examine patterns of biodiversity change using long-term data and large scale environmental drivers, such as climate and land-use.

I am a conservation ecologist interested in the use and application of biodiversity indicators at multiple spatiotemporal scales.

At REC, I am working with different Finnish long-term datasets to identify the main strengths and weaknesses of monitoring schemes in order to find out: (1) which targets are they able to estimate (e.g. in relation to population dynamics) and which biases (e.g. differences in spatial coverage) do they have. The ultimate goal is to learn how we can optimize current monitoring programs.

My background is in conservation biology. In REC, I make use of my experience and connect different data sets containing information on phenological events to understand how the varying ability of different species in matching climate change by shifting their phenologies can make some species more vulnerable than others to the impacts of climate change.

I am an applied mathematician and statistician working with ecological questions. In REC my aim is to develop statistical and computational methods for analyzing large and heterogeneous ecological data. My special interest is in Bayesian methods. 

I am a statistician and mathematical modeller working with ecological and epidemiological questions and applications. Currently I am especially interested in how to best collect and analyze data from nature to understand it's dynamics and mechanisms, e.g. how to design meaningful ecological monitoring studies.

My main background and research interests are in applied ecology and conservation science, with specific focus on evidence-based conservation and global change biology.

For my post-doc at REC I make use of long-term data and advanced modeling frameworks to investigate how species and communities are adjusting to global change, and what is the role of conservation measures, such as protected areas, in mitigating biodiversity loss.


I am studying long-term ecological changes of aquatic communities in response to anthropogenic pressures, such as eutrophication and climate change. I am particularly interested in how changing species composition and distribution patterns alter ecosystem functioning and services. To better understand and predict community responses to environmental change, both on species and on functional trait-based levels, my work focusses on the relationship between environmental drivers and their impact on aquatic ecosystems.
