I am broadly interested in the ecology and evolution of species interactions. For this, I have worked extensively on the spatial dynamics of the insect and pathogen community on the oak tree Quercus robur and the below- and aboveground food web surrounding the perennial herb Plantago lanceolata. I am currently expanding my research to the diseases and insects on semi-wild coffee in SW Ethiopia, and started to explore new study systems associated with Sweden’s perennial plants. Overall, I am broadly interested how ecological and evolutionary interactions between plants, insects and microbes play out in a spatial setting.

My work focuses on plant-associated soil communities. Specifically, I look into spatial patterns of plant-associated soil microbes; their dispersal abilities; how abiotic (e.g. climate, soil pH and nutrients) and biotic factors (e.g. plant genotype and root-associated fungi) can affect them; and what consequences they can have on aboveground communities.
My research mainly focuses on microbial communities associated to plants. I am interested to understand their community structure, function, and interaction with their host and the environment. Previously, I studied the fungal communities of several agricultural crops, including olive, citrus, strawberries, grape, wheat, and apples. Currently, I am studying the microbial community of oak trees with a special focus on their spatial distribution within and among trees, mechanisms of microbial inheritance, acquisition and transmission from the environment.

In August 2015, I received my Master’s Degree in Ecology and Evolutionary Biology from Helsinki University. In 2016, I started my PhD, where I investigate the distribution, drivers and role of microbes within a diverse food web on the pedunculate oak Quercus robur.
In 2018, I was a member of the communication group at our department.

I study how insect communities build up in space and time. In my research, I am particularly interested in the role of plant phenology (bud burst and leaf senescence) in structuring insect communities. As my study system, I use the pedunculate oak (Quercus robur) and a subset of its insect community consisting of leaf miners and gall wasps.
I am a PhD student co-supervised by Ayco Tack (my main supervisor is Kristoffer Hylander). I received a Master’s degree in Nematology (European Masters of Science in Nematology, an Erasmus Mundus Program) from Ghent University in 2014. Since then I had been working at Jimma University (Ethiopia) until I joined Stockholm University as a PhD student in 2016. As my PhD project, I work on the major fungal diseases of coffee along a management gradient of the crop in its native range. I am mainly interested to understand how the variation in biotic and abiotic environmental drivers and coffee management along the gradient could affect the dynamics of the major fungal diseases of coffee.
I obtained my Master’s degree in Ecology and Biodiversity in 2017 at Stockholm University, and thereafter I started my PhD on plant-microbe-insect interactions. Specifically, my research focuses on oak trees and wood anemones, thereby investigating the diseases as well as herbivorous insects related to these plants. I am interested in the performance impacts of pathogens and herbivores when co-occurring on a host plant, as well as the chemical response of the plant to multiple attackers.
I am working in the project “Climate, life-history and a multitrophic food web on oak” and my objective is to understand how spatial and temporal variation in climate affects the voltinism of a diverse community of herbivores and parasitoids on oak and the consequences for food web structure and dynamics.
I just started my PhD. My main interest is in the relationship between climate, biodiversity, coffee diseases and smallholder farmer’s livelihood in southwestern Ethiopia.
Originally from Bath, England. I am in the master’s programme ‘Ecology and Biodiversity’. Currently, I am writing a thesis for my field experiment exploring the influence of oak-sapling’s differing spring phenology and shade levels upon seedling growth, oak powdery mildew (Erisyphe spp.) and herbivory.
My main interest is in the diversity and ecological drivers of nematode communities, for which I sampled hundreds of coffee trees in southwestern Ethiopia, including both trees in natural forests and trees in plantations with lower shade levels.
Etsuko Nonaka is an ecologist and modeler who is interested in the interactions between ecological and evolutionary processes, especially in a spatial context. She uses different kinds of modeling approaches to understand how population dynamics and spatial genetic structure relate to each other and how evolutionary changes can occur in spatially structured populations or metapopulations. She received her PhD from Umeå University in 2014, and has been a postdoctoral researcher at the University of Helsinki (2014-2017) and Stockholm University (2018).

Oliver Moss studied the impact of the abiotic and biotic environment on coffee tree physiology and beneficial root microbes in southwestern Ethiopia.
Jessie Mutz from Florida State University visited us in the autumn semester of 2018. She investigated the patterns and drivers of the within and among tree variation in autumn phenology, as well as the consequences for interactions with plant pathogens and insect herbivores
