Principal Investigator

Associate Professor

My research has mostly focused on how trophic interactions and productivity shape community organization across a variety of different ecosystems including coral reefs, rivers, tall grass prairies, and African savannas.

Project Scientists

Research Scientist

My work is generally focused on how disturbance and biotic interactions influence community structure and dynamics of coral reefs with particular focus on the direct and indirect effects of herbivores on reef systems.

Postdoctoral Researchers

My research focuses on the role herbivorous fish species play in promoting reef health and the intraspecific variability apparent in this role.

My research lies at the nexus of data science, conservation, and ecology, where I employ synthesis methods to study multiscale ecological patterns that inform practical solutions for managing coral reef social-ecological systems. My postdoctoral research is focused on interactions between local and global drivers of coral bleaching as part of a synthesis of global coral bleaching patterns.

My postdoc research is focused on understanding how anthropogenic forcing impacts trophic interactions, particularly those between reef fishes and corals, from community ecology down to microbial scales.

My work is focused on tri-trophic interactions in African savannas. I am particularly interested in understanding how changes in savanna vegetation structure alter herbivore and carnivore communities as well as the feedback between herbivory pressure and plant chemical defences in savanna trees. 

Graduate Students

Ph.D. Student

My current research investigates how local anthropogenic stressors interact on multiple scales to alter coral reef community structure and resilience.

Ph.D. Student

My dissertation work is focused on the restoration ecology of tropical ecosystems, with an emphasis on coral reefs. I am primarily interested in understanding the ecology and drivers of coral reef community recovery, with the ultimate goal of improving coral reef restoration methodologies.

M.S. Student

My current research investigates the invertebrate communities that inhabit corals and how the nature and rate of their excretion contribute to nutrient cycling across a coral reef.

M.S. Student

My research interests include the role of mobile grazing herbivores on disturbed coral reef communities, and the impact of local island fisheries on reef structure and species composition. 

Ph.D. Student

My Ph.D. research will focus on developing new osmosamplers to facilitate the assessment of nutrient dynamics in nearshore coastal ecosystems.

Ph.D. Student

My research will focus on the impact of consumer-derived nutrients in kelp forest ecosystems and how these nutrients affect kelp production and species interactions.

Ph.D. Student

For my current research, I am interested in examining the direct effects environmental stressors have on the physiology and ecology of calcifying organisms and how these stressors may translate into indirect effects on trophic interactions and changes in community structure and dynamics.

Ph.D. Student

For my dissertation research I am interested in the effects of anthropogenic stressors on coral recruitment and juvenile coral survival.
