My areas of research are community ecology, population biology, evolutionary ecology, and phylogenetics. Although I have research projects involving different questions and different experimental systems, almost all involve temporal dynamics, spatial dynamics, or spatio-temporal dynamics – how things vary through time and space. While some projects are purely mathematical, most combine theory and data.

Joe Phillips


I study the intersection of population dynamics, species interactions, and ecosystem processes in aquatic environments. My current research explores the causes and consequences of midge population fluctuations in Lake Mývatn, Iceland.

Amanda McCormick


I am interested in the relationship between ecosystem level processes and ecological communities, as well as trophic interactions. As a graduate student, I am a member of the LTREB project studying Lake Mývatn. Part of my current research focuses on the linkages between the pelagic and benthic habitats of Lake Mývatn. This includes understanding the indirect interactions between benthic and pelagic primary producer communities and how nutrients move between these two habitats (and how the benthic invertebrate community influences this process).

Michael Bosch


My research involves investigating phenotypic plasticity and its population and community effects through multiple spatial and temporal scales.

Lucas Nell

I am interested in the evolution and ecology of species interactions. My PhD research explores how community interactions drive evolution in pea aphids, their symbionts, and natural enemies.

Postdoctoral associates

Rachel Penczykowski

I am broadly interested in the ecology and evolution of host–parasite interactions, and how such interactions both affect and are affected by the abiotic and biotic context in which they occur. My research involves a combination of observational studies of natural populations and communities, manipulative experiments in the field and lab, and mathematical models. I have employed these complementary approaches to study host–parasite interactions in both aquatic and terrestrial ecosystems, and my current research focuses on wild populations of herbaceous plants (e.g., Plantago lanceolata) and their pathogens.

Tanjona Ramiadantsoa

(with Monica Turner)

With a background in mathematics, I find most ecological and evolutionary patterns interesting. As such, my research questions range from physiology to biogeography. Still, I redouble my interest in questions that pertain to conservation especially in quantifying ecological thresholds and transient dynamics. I address these questions by developing mathematical and statistical models. In doing so, I strive to seek a balance between mathematical tractability and biological realism, and aim to foster feedback between theoreticians and empiricists.

Likai Zhu

(with Volker Radeloff [primary])

My research aims to understand the interactions among human, climate and land systems based on remote sensing and geospatial modelling. To be specific, my research interests include land use/cover change, satellite remote sensing of vegetation, climate change and terrestrial vegetation dynamics. Now I am working on the NSF-funded project: The role of taxonomic, functional, genetic, and landscape diversity in food web responses to a changing environment. In this project, I will use remote sensing to characterize cropping patterns, landscape diversity, land surface temperature and other potential variables that give the spatial context of food-web dynamics and evolutionary changes of aphid in the agricultural ecosystems.
