Personal profile

PhD student funded by the London NERC Doctoral Training Partnership and supervised by Dr Alice Milner (RHUL), Dr Celia Martin-Puertas (RHUL) and Professor Helen Bennion (UCL).

PhD title: Understanding lake ecosystem responses to natural and human stressors through the Holocene: a palaeolimnological approach.

My research focuses on the annually-laminated lake record of Diss Mere, Norfolk. Working with my supervisors, we have developed the first Holocene varve chronology for the UK, based on the integration of varve counting, radiocarbon dating and tephrostratigraphy. My project involves the generation of high-resolution palynological, charcoal and diatom data from Diss Mere. This multi-proxy investigation into the interactions between aquatic functioning and vegetation in the catchment, combined with chronological infromation, provides the opportunity to establish the timing, magnitude and direction of ecological response associated with environmental stressors in lake systems.
