Research Specialization

My research program focuses on understanding the mechanisms by which species interactions maintain species diversity, and how we can harness these processes to manage and restore diversity in human-modified systems. I focus on pollinators because they are critical for pollination in managed and natural plant communities, but my research is broadly applicable across ecological interactions. My aim is to discover new insights into how communities form, evolve, and persist through time and space, aiding in the prediction and prevention of community collapse. I combine modeling, synthesis and field-based work, and adhere to the principles of reproducible, open science
