Research summary

I am particularly interested in using palaeolimnological techniques to reconstruct past changes in algal communities and water quality for freshwater lake management. Lake Baikal is an UNESCO World Heritage Site, and is the world’s oldest and deepest freshwater lake. However, this unique ecosystem is threatened by water pollution from industrial development and catchment land-use changes, as well as from climate and environmental change. 

My research will mainly focus on using sedimentary pigment biomarkers (both chlorophyll and carotenoid pigments), to investigate the lakes primary production response to recent pollution and environmental change over the past 1,000 years. From my PhD, I hope to contribute towards the future policy plans to conserve the environment of Lake Baikal.
