My research aims to better understand how species interact with each other and the physical environment, and the effect of these interactions on populations, communities, and ecosystems. I am becoming increasingly interested in understanding how humans are altering these relationships, and identifying ways these effects can be ameliorated. Being based at NGRREC on the banks of the Mississippi River provides a unique opportunity to understand these issues in the context of large river systems. 



Dr. Brittany H. Ousterhout


Britt is a question driven ecologist who seeks to understand how population demography and environmental gradients affect the movement of individuals across the landscape, and ultimately, metapopulation persistence. She combines theory from animal behavior and population biology with experiments, field studies, and robust quantitative approaches to mechanistically understand the process of dispersal and predict the resulting patterns of population dynamics and gene flow. 


Dr. John M. Grady (Starts in November '18)

Postdoc - NGRREC


John is interested in linking biological levels of organization – from cells to ecosystems - across space and time. For instance, how do individual traits, such as body size or metabolic rate, drive emergent ecological properties, like abundance, diversity, and the division of resources? And what principles unify the variety of life? Johns work in our lab will be focused on the role of metabolic assymetry is structuring species interactions, and the distribution of species and their abundance through time and space.

Ashley Olson

PhD Student - Federation University, Australia


Ashley is studying factors behind community assembly on Indo-Pacific islands. Using a unique dataset comprised of vertebrate distributions, as well as their trophic and evolutionary relationships, he hopes to determine what makes a successful colonist and the drivers behind species turnover in tropical island communities.
