Jeff is part of Lincoln Agritech’s Environmental group in Hamilton, working on an MBIE funded programme assessing climate change impacts on the Waikato River, and a Tāwhia te Mana fellowship investigating past seismicity in Aotearoa using cave minerals (speleothems).

With a PhD in geology from the University of Auckland, Jeff specialises in applying geochemical techniques to reconstruct past environmental change and address modern environmental challenges. His research spans the use of cave deposits as archives of past seismic activity (speleoseismology) and hydrologic and climatic change.

Since completing his PhD in 2022, Jeff has helped advance the use of cave deposits in geohazards research, including earthquakes, volcanic eruptions and rainfall extremes. At Lincoln Agritech, he applies this expertise to projects that strengthen earthquake and climate resilience and water management.

Focus areas:

• Cave deposits as records of geohazards
• Geochemical techniques for environmental and geological research
• Climate change impacts on freshwater systems
