David Claessen

David Claessen, CERES Ens, Paris, France
David is a researcher at the Institut de biologie de l’Ecole Normale Supérieure, CNRS-ENS-INSERM UMR8197, in the Research team Eco-evolutionary mathematics (EEM). His work focuses on ecology and evolution of physiologically structured populations, adaptive dynamics of complex ecological systems, agro-ecology : an eco-evolutionary ecological approach to crop epidemics, and evolutionary ecology of marine phytoplankton in simple and complex models.
He is also the director of the CERES Ens and co-organiser of the Summer School.

Mick Follows

Mick Follows, MIT, MA, USA
Mick is Associate Professor of Oceanography in the Department of Earth, Atmospheric and Planetary Sciences at MIT. He seeks to understand how the interactions of physical, chemical and biological processes modulate the structure and function of marine microbial communities and regulate elemental cycles on the global. He develops and employs idealized theory, numerical simulations and analysis of observed data to identify the relationships of individuals and communities to their environment, connecting cellular-scale processes to global microbial community structure.

In particular, his team has created a marine ecosystem model that, when initialized with many phytoplankton types whose physiological traits have been determined stochastically, results in emergent community structure and biogeography consistent with known distributions of microbes in the global oceans.

A major focus of the current work of the Marine Biogeochemical Modeling group he balongs to is The Darwin Project: An interdisciplinary, inter-deparmental effort at MIT to model marine ecosystems and understand how they are regulated by, and feedback upon, the environment. More...

Michael Ghil

Michael Ghil, ENS, France and UCLA, USA
Michael obtained his Ph.D. from New York University’s Courant Institute of Mathematical Science in 1975. He is a Distinguished Professor of Geosciences (emeritus) at the Ecole Normale Supérieure, Paris, past Head of its Geosciences Department (2003–2009) and founder of its Environmental Research and Teaching Institute. He is also a Distinguished Research Professor at the University of California, Los Angeles, where he was Chair of the Department of Atmospheric Sciences (1988–1992) and Director of the Institute of Geophysics and Planetary Physics (1992–2003).

Michael Ghil is a founder of theoretical climate dynamics, as well as of advanced data assimilation methodology. He has applied systematically ideas and methods from nonlinear dynamics to planetary-scale flows, atmospheric and oceanic. He has used these methods to proceed from simple flows with high temporal regularity and spatial symmetry to the observed flows, with their complex behavior in space and time. His studies of climate variability on many time scales have used a full hierarchy of models, from the simplest ‘‘toy’’ models all the way to atmospheric, oceanic and coupled general circulation models. More recently, he has applied ideas and methods from nonlinear and complex dynamics to ecological and economic networks. More..

André de Roos

André de Roos, University of Amsterdam, Netherlands
Back in 1985, André started his research on investigating numerical methods for physiologically structured population models to ultimately allow application of these models to a broad range of ecological and evolutionary problems. It resulted in a technique called The Escalator Boxcar Train (EBT) to analyze interesting problems in structured population dynamics.

Now, his work at the Institute for Biodiversity and Ecosystem Dynamics focuses on the relationship between individual life history, in particular ontogenetic development, and the dynamics of populations and communities. His main tool to address questions about the connection between individual life history and population dynamics is a class of models, known as physiologically structured population models. State concepts are introduced at both the individual and the population level and model formulation is entirely restricted to individual-level, life history processes. The dynamics of the population simply result from keeping book of all individual-level changes.More...

 

Special topic speakers

Judith Bronstein

Judith Bronstein, University Distinguished Professor, Ecology and Evolutionary Biology, The University of Arizona, AZ, USA
Judith Bronstein’s lab focuses on the study of interspecific interactions, particularly on the poorly-understood, mutually beneficial ones (mutualisms). Specific conceptual areas of interest include: (i) conflicts of interest between mutualists and their consequences for the maintenance of beneficial outcomes in these interactions; and (ii) context-dependent outcomes in both mutualisms and antagonisms. Using a combination of field observations and experiments, she is examining how population processes, abiotic conditions, and the community context determine net effects of the interactions for the fitness of each participant species. She is also collaborating on theoretical and empirical investigations of (i) the fragility of mutualism in light of conservation threats and mechanisms of restoring disrupted interactions; and (ii) the causes and consequences of "cheating" within mutualism.

Margaret Evans

Margaret Evans, LTRR Lab, The University of Arizona, AZ, USA
Margaret is a plant population biologist with research focused in two areas: 1) conservation ecology, including the development of general tools for population and range modeling, as well as building knowledge about particular rare species, and 2) evolutionary ecology, including bet hedging, life history evolution, breeding system evolution, and comparative analyses of the evolution of climatic niches. Since starting a joint appointment split between the Laboratory of Tree-Ring Research and the Department of Ecology and Evolutionary Biology, her research focuses on building process-based models to forecast how western U. S. tree species will respond to climate change. This involves the integration of large data sets (Forest Inventory and Analysis, the International Tree Ring Data Bank, and the Botanical Information and Ecology Network) via hierarchical Bayesian statistical models.

Benoit Hazard

Benoit Hazard, EHESS, Paris, France
Benoit is an Anthropologist, researcher at CNRS (CR1) and is based at Ecole des Hautes Etudes en Sciences Sociales (EHESS) Paris. After a generation of research on african migration in Southern Italy, he has undertaken a new research on the future of pastoral landscapes in the anthropocene by focusing on interaction between pastoralism, conservation and large scale investment in rangeland of Kenya. The social change occurring in the central rift valley is captured through the ethnography of resilience, adaptation and resistance of the margins to their inclusion in the global economy. This ethnography allow to discuss the bio cultural frontiers of pastoralism in the anthropocene by looking at how the natural resources (water, pastures, forest) on which pastoralist depend are impacted by conservation project as well as large scale investment in the rangeland such as geothermal project.

Elise Thébault

Elisa Thébault, iEES-Paris, UPMC, Paris, France
Elisa Thébault studies ecological modeling: impact of biodiversity loss on ecosystem functioning, trophic and mutualistic interactions in complex networks, effects of land use and climate change on soil food webs and related ecosystem services, effects of fishing on marine food webs; and the analysis of ecological network topology: pollination and herbivore networks, soil food webs, marine and lake food webs. Dr. Thebault is trained in theoretical ecology, and one of her main research interest concerns how diversity and interactions between species influence community properties, stability and ecosystem functioning, both in aquatic and terrestrial ecosystems. Her work on the links between diversity and stability has shown that biodiversity can provide an insurance against environmental disruptions and thus promote the stability of ecosystems. In particular, she has shown that the diversity-stability relationship depends on the strength of trophic interactions and its trade-off with diversity, as well as on the type of interactions between species and on the structure of ecological interaction networks. Her work has been published in 12 articles in journals of rank A, as well as in one book chapter. More...
