Career Trajectory
Bio
One of the hallmarks of living organisms is the change they induce in their abiotic and biotic environments. For instance, earthworms affect soil structure, beavers build dams, bees construct nests, trees lower light levels under their canopies, butterflies pollinate flowers, etc. Through their development, physiology, and behavior, organisms alter the world in which they live and these effects can feed back to influence their ecology and evolution. This process has been labeled niche construction (or, alternatively, ecosystem engineering). Using a combination of analytical, simulation-based and lab-experimental techniques, we study different biological systems that possess strong niche construction elements, including fire-prone flora with plant traits that enhance flammability, learning organisms that alter the form and frequency of their stimuli, bacteria that produce anti-bacterial toxins, and hosts and pathogens that continually coevolve. Recently, we have focused on how the incorporation of spatial structure can drastically affect the eco-evolutionary dynamics of these and other niche construction systems. We have also started to explore (both theoretically and experimentally) how altruistic forms of niche construction evolve in relation to various forms of population structure.
