Dr Charlotte Braungardt

Associate Professor (Senior Lecturer) in Environmental Science

School of Geography, Earth and Environmental Sciences (Faculty of Science and Engineering)

I am Associate Professor (Senior Lecturer) in Environmental Science and Assistant Head of School for Environmental Science within the School of Geography, Earth and Environmental Sciences (SoGEES). My main roles in learning and teaching are in BSc (Hons) Environmental Science and MSc Environmental Consultancy.
I am a member of the Biogeochemistry Research Centre (BGC: http://www1.plymouth.ac.uk/research/bgc/Pages/default.aspx ), it's sub-group Biogeochemistry and Environmental Analytical Chemistry (BEACh:  http://www.plymouth.ac.uk/research/beach ) and the Environmental Science Research Group. My research activities centre around the geochemistry of mine waste and its impact on the aquatic and terrestrial environments and mitigation.


In my previous career, I graduated as a Dipl.-Ing. Electrical Engineering/Communication Electronics in 1989 and worked as a project engineer in industrial process controll systems for the engineering consultancy Metallurgische Gesellschaft/LURGI in Germany until 1993.
I obtained a BSc Environmental Science at the University of Plymouth in 1996 and continued my scientific training with a Ph.D. in marine geochemistry (Metal biogeochemistry of a mine contaminated estuarine-coastal system in SW Spain) at the same University in 2000. Two EU-funded post-doctoral research fellowships followed between 2000 and 2003, on the projects MEMOSEA (UV digestion of metal complexing natural organic matter and humic substances) and IMTEC (In situ automated monitoring of trace metal speciation in estuaries and coastal zones).
Between 2001 and 2006, I took on various part-time lecturing roles in environmental science and marine science and obtained the LTHE (Learning and Teaching in Higher Education) qualification. My permanent position as lecturer at the University of Plymouth commenced in 2006.

Teaching interests

My teaching activities centre around our BSc Environmental Science programme and the MSc Environmental Consultancy course. As a lecturer, my focus is on catchment science, geochemistry,  water resources, scientific method and skills development; the latter including practical scientific investigations, providing opportunities for work experience, as well as introducing advanced IT skills, such as GIS, to the programme. 
The development of life skill alongside academic credentials is key to the personal and professional development of our graduates. In this context I am working on embedding into the curriculum opportunities for our students to obtain and practice their communication, leadership and management skills and become resilient individuals and confident professionals. I am member of the University Mental Health Taskforce.

Research interests

My research interests lie in the geochemistry and biogeochemistry of catchment systems, from headwaters to estuaries and into the coastal zone. Current research projects investigate point and diffuse sources of elements associated with metal mining activities and the impact of contamination on aquatic and terrestrial environments, the assessment of risk for humans from uptake of metals and metalloids into the food chain and mitigation and remediation measures. For this work, collaboration with external partners include local organisations (e.g. Tamar Valley Service), as well as the Environment Agency, Camborne School of Mines, the British Geological Survey, the International Zinc Association and the European Copper Institute. My recent sabbatical at the University of Montpellier II has complemented my research interests in the area of remediation of metal mining legacies.
