I am responsible for teaching physical geography topics at St John's College. These currently include geomorphology, biogeography, climatology and Quaternary Science, but are subject to change in response to the department syllabi. I also teach lectures in the School of Geography and Environment.
Before coming to Oxford in 2013, I undertook degrees at the University of Sheffield (BSc Geography), Royal Holloway, University of London (MSc Quaternary Science), and Aberystwyth University (PhD Geography). During my time here, I have successfully completed the University of Oxford Enhancing Teaching Programme, accredited by the UK Staff and Educational Development Association.
My research focuses on the reconstruction of climate and environment over the past 2.7 million years (known as the Quaternary Period). I mainly focus on dryland regions, and am most interested in the interaction between ancient civilisations and climate change over the past 10,000 years.
current research projects include:
- Examining river activity over the past 10,000 years in northwest India to understand the relationship between changing hydrology and civilisation collapse.
- Understanding the relationship between changing lake levels and ancient human activities in the Thar Desert, India over the past 100,000 years.
- Quantifying the evolution and relationship between dryland river activity and dune building/migration in the Simpson Desert, Central Australia.
- Development of the sediment dating technique luminescence dating.
