Staff Profile:Dr Emma Versteegh

Name:

Dr Emma Versteegh

Job Title:

Postdoctoral Research Assistant - Stable Isotope Geochemist

Responsibilities:

Areas of Interest:

Emma's main research interest is the reconstruction of past environmental variability through geochemistry of biogenic carbonates.

The main focus of her current research is on the stable isotope composition of earthworm secreted calcite granules, with the aim to construct a new terrestrial palaeo-environment thermometer. Recent research has included:

• Bivalve nitrogen isotope composition recording human impact.
• Bivalve shell chemistry as a meltwater proxy in the Arctic.
• Freshwater bivalve oxygen isotope compositions as archives of past floods and droughts.
• The construction of bivalve growth models using seasonal stable isotope fluctuations in the shell.
• Stable carbon isotope chemistry of bivalves.

Research groups / Centres:

• Earth Systems Science Research Group
• Soil Research Centre

Key Facts:

Emma joined the department in October 2010. She completed her PhD on biogeochemistry of freshwater bivalves and its application in the reconstruction of past environments in 2009 at the VU University Amsterdam. She then worked as a postdoctoral researcher at the Vrije Universiteit Brussels within the CALMARS project (CALcareous MARine Skeletons as recorders of global climate changes).
