Research Associate / Senior Research Associate in Biochemistry and Ecology of Coral Venom

The role

We are looking for an enthusiastic postdoctoral scientist to join Maria Sachkova’s group to conduct research on the NERC-funded project “The Role Of Venom In Coral Resilience”. The project is for 3 years starting February 2026, in collaboration with Cecilia D’Angelo, University of Southampton. The main goal of this exciting project is to reveal if venom and heterotrophic feeding play a role in surviving bleaching in corals. The work will involve characterisation of venom composition and biosynthesis dynamics under bleaching in several coral species by proteomics, transcriptomics and other lab techniques. Maria’s group has access to genomics, proteomics and aquarium facilities at Bristol. The project benefits from access to the aquarium facility at Southampton, that maintains multiple coral species under controlled conditions. 

Project description: 

Global climate change is leading to the decline of coral reefs, mostly due to the phenomenon of coral bleaching. Corals obtain nutrients either autotrophically from their algal endosymbionts or by feeding on planktonic prey (heterotrophy). During bleaching, the symbionts are lost and coral risk starvation, often leading to death. However, many corals can survive some episodes of bleaching by increasing their capability for heterotrophic feeding. To catch prey, corals use venom produced by specialised stinging cells. Venoms are metabolically expensive to synthesize but they can play a key role in allowing corals to overcome energy depletion during bleaching and therefore might be a key resilience mechanism. Little is known about the composition of venom in corals and its role in coral nutrition and responses to environmental disturbance. This project will establish the role of venom in surviving bleaching in corals using biochemical and molecular approaches as well as experiments with live corals cultured at University of Southampton. Being at the intersection of animal venomics and coral ecology, this project will provide new insights into the key aspects of coral biology at organismal, molecular and cellular levels.
