    Elizabeth Hobson
    Postdoctoral Fellow at the Santa Fe Institute; Assistant Professor, Department of Biological Sciences, University of Cincinnati (August 2019)

    I am a biologist who specializes in animal behavior, behavioral ecology, cognitive ecology, and social cognition. My research focuses on social information: what animals know about their social worlds, how they come to know it, and what they do with that information.

    To address these questions, I integrate aspects of ecology and evolution to determine how the combination of sociality and cognition affect the emergence of group social structures from a combination of individual-level social actions, cognitive abilities, and decisions about future interactions. Combining this perspective into a feedback loop, and developing and applying new quantitative tools, allows me to back-infer what animals know about their social worlds by looking at how their decisions about social interactions are contingent on different kinds of social knowledge. Detecting the use of social knowledge provides new insight into the connections between social decisions and cognitive processing, how they can be affected by ecological dynamics, and how they can lead to the evolution of complex sociality.

    Much of my previous research focused on avian sociality, where I investigated social behavior and network structures in parrots. In my current research I apply these tools to a much wider range of species, from ants to primates, and even humans, while incorporating more quantitative and computational approaches.

    I am currently a Postdoctoral Fellow at the Santa Fe Institute, where I am studying the ecology and evolution of animal sociality. I will be starting a faculty position at the University of Cincinnati in August 2019. My goal for research in my lab is to use rigorous comparative methods and an evolutionary perspective to discover ways in which the extreme sociality of some species emerged, through investigating what individuals understand about their social worlds and the strategies individuals use to balance the costs and benefits of social living.

    Daniel B. Larremore
    Asst. Professor, Univ. Colorado Boulder
    BioFrontiers Institute & Dept. of Computer Science

    My research focuses on developing methods of networks, dynamical systems, and statistical inference, to solve problems in social and biological systems. I try to keep a tight loop between data and theory, and learn a lot from confronting models and algorithms with real problems.

    I obtained my PhD in Applied Mathematics from the University of Colorado Boulder in 2012, advised by Juan G. Restrepo, after which I spent three years as a postdoctoral fellow at the Harvard T.H. Chan School of Public Health studying the genetic epidemiology of malaria in the Center for Communicable Disease Dynamics. I then joined the Santa Fe Institute as an Omidyar Fellow until 2017, when I joined the faculty at the University of Colorado Boulder in the Department of Computer Science and the BioFrontiers Institute.
    Malaria's antigenic variation and evolution - The var genes of the malaria parasite P. falciparum evolve according to complicated and unknown rules, with selective pressures at multiple scales both within hosts and between hosts. I create and use mathematical tools to understand the structural and evolutionary constraints on var gene evolution, and their relationships with parasite virulence, population structure, and epidemiology.

    Networks and theory - The processes that generate complex networks leave hints about themselves in the patterns of edges, and the relationships between those patterns and vertex metadata. I work on mathematical descriptions of graph ensembles, inference of community structures, vertex ordering or ranking, and using metadata to better understand network formation.
    The scientific ecosystem - The scientific method of hypothesis, experiment, and conclusion poorly describes modern scientific discovery and productivity. Instead, science is done by people who play various social roles in the ecosystem of science. I investigate faculty hiring, productivity patterns, scientific careers, and the dynamics of discovery through large-scale data collection and modeling.

    Professor, Department of Science and Technology, TÉLUQ University

    I am a professor in the Department of Science and Technology at TÉLUQ, Université du Québec, and a member of the Centre for Forest Research and Quebec Center for Biodiversity Science.

    I am interested in applying concepts and models from complex systems science to study forest ecosystems at multiple scales. My interdisciplinary research activities are focused on developing quantitative, theoretical and applied modelling and analysis tools in the study of two main themes:

    The dynamics of ecological communities in forest landscapes.
    How do inter- and intraspecific interactions between individuals, and their dispersal ability influence the dynamics of their population at different temporal and spatial scales?
    The interplay between forest management and forest function.
    How do interactions between ecological processes and management affect the dynamics and function of forest ecosystems?

    Dominique Gravel - Professor, Holder of the Canada Research Chair in Integrative Ecology, Université de Sherbrooke

    Research Themes:
    Spatial ecology, biogeography and ecology of metacommunities; Networks of ecological interactions; Theoretical, numerical and computational ecology; Biodiversity and ecosystem functioning; Climate change and forestry.

    Current Research:
    Ecosystems are difficult to study because of the diversity of interactions between species and their complex relationships with the environment. If understanding the distribution of biodiversity is already a challenge, predicting its response to global change is even more so. I adopt a research approach that integrates several disciplines of ecology to better understand the impact of global changes on biodiversity. Thus, I use notions of biogeography, community ecology and ecosystem functioning.

    My research program ultimately aims to develop a global model of ecosystem functioning. To do this, I propose new conceptual tools and implement them using mathematical and computer models, as well as massive data ( Big Data ). I also carry out laboratory experiments using a microbial ecosystem (the food web inhabiting the leaves of carnivorous plants). My research will produce biodiversity scenarios for the future. This knowledge is needed to protect biodiversity in a changing environment.
