Public Engagement

Learning events, The Natural History Museum and UCL, London        2009 - present

  • Regularly participate in ‘meet the scientist’ events delivered in the public galleries

  • Participate in A-level Geography taster courses, at University College London, to enable students to experience the laboratory techniques used to reconstruct past climates and environments and to encourage students to apply to university

  • Demonstrator on ‘Chironomids: water quality and climate change’ short course organised by the Environmental Change Research Centre, Department of Geography UCL and NHM  

Associate lecturer, The Open University          2009 - present

  • Tutoring undergraduates on the level 2 Geology course (S276)

  • This involves marking and providing feedback on assignments, running field trips and tutorials, helping the students understand the course material and prepare for the end-of-course assessment

Research

Interests

My main areas of interest are determining the extent and impacts of past and present climate change on mid to high latitude ecosystems. In my research I use chironomid midges preserved in lake sediments to make quantitative estimations of past climate. Chironomidae is a family of two-winged flies (Insecta: Diptera), often referred to as Chironomids or non-biting midges, and they are sensitive indicators of past climates. The winged adults disperse widely and lay their eggs in water bodies. If the environmental conditions are suitable the eggs hatch and develop through larval and pupal stages before emerging as adults. In many freshwater systems their larvae are abundant and diverse, there are 5000 described species and up to 15000 species may exist in total. The larval head capsules are usually well-preserved in lake sediments and most specimens are identifiable at least to generic level. Many species are stenothermic (only capable of surviving within a narrow temperature range) so a small change in temperature can lead to a different assemblage of larvae within the lake. Analysing subsamples from lake sediment cores enables the chironomid assemblages to be recorded over time and from this data the changes in environmental conditions can be estimated.

Holocene climate reconstructions from arctic and subarctic Russia

For my Ph.D. I investigated the response of chironomids to past and present environmental change in Arctic Russia.  Average arctic temperatures have increased at almost twice the rate of the rest of the world over the last 100 years (IPCC 2007) and this trend is predicted to continue as high latitudes are predicted to warm by 4 - 7°C in the next century (ACIA 2004, 2005). Arctic Russia is often poorly represented in the global perspective of climate trends and their affects on ecosystems due to the scarcity of observational or proxy records.  By compiling a data set of lakes from northern European Russia to central Siberia in collaboration with David Porinchu, Ohio State University, USA and Larisa Nazarova, Alfred Wegener Institute, Potsdam I developed chironomid-based inference models to reconstruct July air temperature and continentality (Self et al. 2011). I applied these models to lake cores from the Pechora Basin, North-east European Russia and Putorana Plateau, western Siberia to produce estimates of changes in July air temperature and continentality over the past 11,500 years. The climate reconstructions from European Russia formed part of palaeoenvironments work package in the EU funded CarboNorth project. The models have also been applied by the palaeolimnological research community to interglacial and Holocene sequences from central and NW Europe.

The Holocene climate of Kamchatka

I am currently investigating Holocene climate change in Kamchatka, the Russian Far East as part of a multi-proxy project including chironomids, oxygen isotopes, diatoms and pollen to improve our understanding of the climate teleconnections between the North Atlantic and the North Pacific.
