Sean R. Connolly

Sean R. Connolly is a Research Professor at the Smithsonian Tropical Research Institute (STRI) in Panama, where he leads the Connolly Lab focused on coral reef ecology and biodiversity dynamics. He joined STRI in late 2019 after approximately 20 years of research on Central Indo-Pacific coral reefs, and now directs his research toward the coral reefs of the Tropical East Pacific and Caribbean regions.

Dr. Connolly's research interests center on understanding the mechanisms that maintain biodiversity in species-rich systems, particularly coral reefs. His work investigates how large numbers of species coexist despite similar resource requirements, what determines the commonness or rarity of different species, how fishing and marine reserves impact reef ecosystems, and how coral reefs respond to climate change. His approach combines empirical field studies with mathematical and statistical modeling across multiple spatial and temporal scales.

His publication record demonstrates a strong focus on coral reef community dynamics, biodiversity patterns, climate change impacts, and fisheries management. Recent work increasingly addresses the effects of multiple stressors on reef ecosystems, with growing attention to the Tropical Eastern Pacific as a comparative natural laboratory. His collaborative research spans multiple institutions globally, reflecting the international nature of coral reef science.

Dr. Connolly received his B.A. from Earlham College in 1994 and his Ph.D. from Stanford University in 1999. His educational background provided the foundation for his interdisciplinary approach that bridges theoretical ecology with practical conservation applications.

His research program currently investigates reef ecosystems on both sides of the Isthmus of Panama, taking advantage of the dramatically different reef conditions in the Tropical East Pacific (where one coral group dominates marginal reef conditions) and the Caribbean (where former community dominants have collapsed to a fraction of historical abundances). This comparative approach provides unique insights into the mechanisms of biodiversity maintenance and ecosystem resilience.
