    Research Summary

    Broadly, I am a community ecologist who uses ecological theory and statistical modeling to link observed community patterns to underlying processes. More specifically, I am interested in the assembly and services of host-associated microbial communities, such as those in mammalian guts and on the roots and leaves of plants. Conceptually, my current research falls into three general areas: (A) patterns and processes of host-associated microbial succession; (B) host-microbiome feedbacks and alternative stable states, especially those triggered by pathogens to enable their rapid expansion; and (C) microbial community resistance and resilience to disturbance and immigration.


    Biographical Info

    I am currently a postdoctoral researcher at Michigan State University, co-advised by Ashley Shade, Elena Litchman, and (unofficially) Chris Klausmeier. I work on various projects related to the microbial ecology of the human gut. I also spend time working on projects related to microbial resistance to disease, and general community ecology theory. I did my dissertation at University of Michigan in the Department of Ecology and Evolutionary Biology, which focused on trying understand and predict how grasslands will respond to climate change. Before that, I spent several years traveling and working public service jobs in Namibia, Ecuador, and Colombia. I did my undergraduate at Grinnell College.

    Research Summary

    A central focus of my research is to connect individual-level processes to population-level outcomes. These cross-scale interactions are key to understanding things like eco-evolutionary dynamics, shifts in demography, population stability, and disease outbreaks. Moreover, connecting multiple scales of biological organization is proving increasingly crucial for addressing public health challenges such as the development of “evolution-proof” strategies to slow the evolution of virulence and antibiotic resistance.

    My research program emphasizes the use of multi-disciplinary and quantitative approaches to science. My research lies at the interface of three traditionally separate bodies of research: consumer-resource ecology, physiology, and evolutionary epidemiology. I work within several focal systems and have developed collaborations with mathematicians, physiologists, ecologists, and conservation managers. Working across disciplines helps me think ‘outside the box’ and develop a unique skillset in meditating across multi-disciplinary teams.

    My aim is that by bringing a theory-guided approach and an ecological lens to these important questions, the Hite lab will become a leader in translational research. To test (and advance) theory, my research program uses a variety of lab-based and natural systems as case-studies including freshwater zooplankton and fruit flies and both bacterial and fungal pathogens.


    Biographical Info

    I am a quantitative eco-evolutionary biologist. My research lies at the interface of physiology, ecology, and evolutionary epidemiology. Broadly, I study how ecological variation shapes the interaction between individual life histories and the dynamics of populations and communities.

    My approach integrates empirical and observational data with innovative statistical approaches (e.g., machine learning) and mathematical modeling. I use theory from population ecology and evolutionary epidemiology as a guide to develop and test general, yet mechanistic models that advance multiple fields.

    Research Summary

    For the past 10 years, my main focus has been on metamorphosis in the ocean, a process that has evolved numerous times in animals and non-animals. Across kingdoms, planktonic propagules face similar challenges: surviving (and in some cases growing) util they reach a "competent" stage to transform into juveniles, identification of suitable juvenile habitat when they arrive there, deciding whether to settle therein or wait for a potentially higher quality settlement habitat, and accomplishing the transformation itself. I use the word "challenges" here purposefully, as these early life stages need to function effectively as larvae and then make instantaneous decisions to abandon that life stage, undergoing what can be profound physiological and morphological changes into a benthic juvenile stage. A detailed understanding of this common yet diverse life cycle transformation that occurs at metamorphosis in marine organisms is not merely an intriguing cross-disciplinary problem, it represents a major knowledge gap that limits our understanding of and ability to predict trends in marine populations. In the face of profound anthropogenic ocean change, increasing our knowledge of these issues will be a key piece in our efforts to protect threatened marine ecosystems.


    Biographical Info

    I am broadly interested in the nexus of ecology, development and evolution. Specifically. I am fascinated by how organisms assess their internal and external environments to make informed, consequential life history decisions. To me, the ultimate example of this phenomenon is metamorphosis, a process that has evolved numerous times in both animals and non-animals. I have studied the internal mechanics of metamorphosis –where developmental changes underlie both subtle and profound evolutionary change– and how marine larvae evaluate their external environment in order to increase their very long odds of recruitment into adult populations. I am committed to addressing climate change, which I have done largely through educational outreach.

    Biographical Info

    John Hutchinson is a Professor of Evolutionary Biomechanics. John's research straddles the fields of evolutionary biology and biomechanics, with an emphasis on how very large animals stand and move and how locomotion evolved in different groups of land vertebrates. He is an American biologist who found a new home in the UK as a dual citizen. He gained a BS degree in Zoology at the University of Wisconsin in 1993, then received a PhD in Integrative Biology at the University of California with Kevin Padian in 2001, and rounded out his training with a two-year National Science Foundation bioinformatics Postdoctoral Fellowship at the Biomechanical Engineering Division of Stanford University with Scott Delp. John started at the Royal Veterinary College as a Lecturer in Evolutionary Biomechanics in 2003 in the Department of Veterinary Basic Sciences (now Department of Comparative Biomedical Sciences), in 2008 became a Reader, and in 2011 became a full Professor.

    Research Summary

    How do organisms respond and adapt to complex, variable natural environments? Our research integrates environmental physiology, ecology and evolution to address this question, using a combination of laboratory, field and modeling approaches. Much of our work is with temperate insects and their interactions with plants, but together with recent graduate students and colleagues we have also studied bacteriophage, echinoderm larvae, and tropical butterflies. One major theme in recent years is plastic and evolutionary responses to human-induced environmental changes—climate change, invasive species, agroecosystems—and their ecological consequences.


    Biographical Info

    Joel was educated at St. Camillus Elementary, Thomas Johnson High, Duke, Wisconsin, Stanford, and UC-Berkeley, and held faculty positions at Brown University and University of Washington before moving to UNC in 2001. Over the years his research has involved biomechanics, environmental biophysics, physiology, ecology and evolution, but current foci are evolutionary and physiological ecology and population biology, mostly with insects and insect-plant interactions. He has a long-standing interest in educational software, and more recently in communicating science to non-science audiences. In his spare time Joel likes to hike and play guitar, and sometimes writes songs about biology.
