Ludvig Bohlin is a PhD student in computational science and engineering with specialization in Physics. He is interested in understanding real-world complex systems, and their impact on spreading and communication of information: Why do some messages and ideas propagate while some don't? Personal webpage.

Folmer Bokma is researcher in evolutionary biology. His area of research is macroevolution, that is evolution over periods of time that are so long that they span the emergence and extinction of species. He is especially interested in how species emerge, and what determines whether they will adapt to a changing environment or go extinct. The organisms that species consist of are not a loose collection of traits but a functionally integrated complex. Modern, high-throughput molecular genetic techniques now allow for genome-wide measurement of for example gene (co-)expression or copy number, and this allows studying thousands of functionally related traits. Folmer develops models and analyses to study their long-term evolution, to better understand the “evolvability” of complex organizations. Personal webpage.

Åke Brännström is senior lecturer in mathematical ecology. His main interest is evolutionary and ecological dynamics. Ongoing collaborative efforts aim to understand vegetation structure, shed light on the emergence of cooperation, and develop efficient numerical methods for structured populations. Personal webpage.
Sebastian Diehl is a professor in ecology. He studies consumer-resource, food web, and ecosystem dynamics both empirically and theoretically. Ongoing theoretical work focuses on the influence of food web structure, ontogenetic niche shifts, and elemental stoichiometry on food web and ecosystem dynamics, and on the influence of vertical resource (light, nutrient) gradients on pelagic and benthic aquatic systems. Personal webpage.

Daniel Edler is a research engineer with a background in physics. He develops research tools to visualize complex systems, with the aim of turning big data into powerful representations (mapequation.org). 
He is inspired by the art of cartography: Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate relevant information effectively. Personal webpage.

Petter Holme is senior lecturer in complex systems. His research aims at answering concrete questions about networked systems via structure and dynamics of the networks. How can we slow down the spreading of disease? How can we make Internet faster and more energy efficient? How can we find important genes for different diseases. Personal webpage.
Jungkoo Kang is developing mathematical models and computer programs as a postdoctoral research associeate at Integrative Science Laboratory (IceLab) in Umeå University. These programs are used to predict the changes in the morphology of commercially important fish (i.e. alewives and whitefish) for sustainable fisheries management. Personal webpage.
Magnus Lindh a PhD student in mathematical ecology interested in traits that shape plant ecology and evolution. Depending on the environment traits describing a species will evolve to stable states, and sometimes form two new species. My projects are: Crown architecture in latitudinal gradients, root and shoot allocation depending on ground water, the flowering timing in a changing climate with light competition, and two dimensional size structured models. Personal webpage.
Ludvig Lizana is an associate senior lecturer in physics. His main interest is in theoretical aspects of biophysics where he has worked on number of different problems. A few examples include: How the spatial dynamics of DNA affect gene regulation, Electrophoresis of macro ions (e.g. polyelectrolytes and DNA) in electrolytes, Evolution of bacterial metabolic networks, and Spatial dynamics of information spreading under discrimination in living systems. Personal webpage.
Niklas Lundström is post-doc in mathematics. His area of interest is differential equations, both theory and applications. In particular, existence, uniqueness and regularity of solutions to partial differential equations, theory of dynamical systems such as bifurcations and basin of attraction and applications to the above theory, especially in ecology and mechanics. Personal webpage.
Markus Nyberg is a PhD student in Theoretical Physics. MSC from Stockholm University. Research  interests are non-equilibrium statistical processes driven by different Gaussian noises. Main focus is on first passage dynamics applicable to cell biology. Personal webpage.
Lennart Persson is professor in aquatic ecology. His research deals with the effects of ontogenetic development on population and community dynamics. Of particular present focus are the effects of size/stage differences in energetic efficiency on ecological dynamics. Research approaches include experimental studies from laboratory to whole lake systems, time series analyses and modeling using stage-based as well as fully size-structured models. Personal webpage.
Raffaele Rani is a PhD student in Mathematical Ecology. His research deals with the use of L-systems and the theory of parallel rewriting grammars in the simulation and study of the architectural growth of plants. They aim at understanding the evolution of traits and trade-offs of trees. Personal webpage.
Martin Rosvall is an associate senior lecturer in complex systems. He uses both both data-driven and model-based approaches to connect structure with dynamics in integrated social and biological systems. The overall purpose of this research is to make use of today’s data explosion to better comprehend the flow of disease, information, and money through living systems. One specific aim is to combine fundamental information-theoretic principles with efficient algorithms and powerful visualization tools into efficient maps that simplify and highlight important structures in the dynamics of living systems. Personal webpage.
Xavier Thibert-Plante is senior lecturer in theoretical ecology. His main research interest is in biological non-linear phenomena, such as feedback loops. He is currently working on the feedback loop between gene flow and local adaptation in different ecological context such as intraguild predation, competition for heterogeneous resources, and climate change. He is studying the evolution of biodiversity, species range and mechanisms of non-random mating. This research program is built on the expertise that he developed while studying the process of ecological speciation, a special case in which local adaptation reduces gene flow. Personal webpage.
Jonas Wickman is a PhD student in mathematical ecology. His main research interest is in understanding evolutionary processes in spatially structured systems, as well as the development of mathematical and computational methods for efficiently studying such systems. Some examples are the study of the effects of the competition for heterogeneously distributed resources on diversity and speciation, and the comparison between individual-based and partial differential equation-based modeling of spatially structured evolutionary systems. Personal webpage.
Lai Zhang is a postdoc in mathematical ecology. He is interested in both ecological and evolutionary dynamics of populations and food webs using both Lokta-Volterra models and size-structured population models formulated as PDEs. He is also interested in pattern formations in physical space using reaction-diffusion equations. Personal webpage.
