Research Interests

​My interests lie in the complexities of incorporating species interactions into predictive models, especially species conservation models related to human-induced climate change. I am interested in network models of plant-pollinators that recognize the competitive relationships between pollinators. In addition, I hope to build more realistic models that are incorporate more empirical findings. Some topics I hope to address in my PhD are:

  • Experimentally testing shifts in phenology mismatch between plants and their pollinators
  • Understanding how species losses from plant-pollinator networks affect network stability and structure
