Research Themes and Scholarly Interests

I am a quantitative physical geographer, interested in the interactions between earth surface processes and topography. My current research interests can be organised into the following three inter-related categories landslide hazard and risk mapping, participatory mapping and geomorphological, environmental and digital terrain modelling.

I am currently a Research Fellow on the Global Challenges Research Fund Sajag-Nepal: Preparedness and planning for the mountain hazard and risk chain in Nepal project working with Dr. Katie Oven and Dr Amy Johnson here in Northumbria and with a large interdisciplinary team of social and physical scientists and anthropologists in Nepal, the UK, Canada, and New Zealand. Within this large project I am both examining shifting patterns of hazard and risk but also our approaches to mapping exposure to these cascading hazard systems.

Before joining Northumbria in January 2023 I worked as a PDRA at Durham University on the following projects:

Participatory approaches to make big data on disaster risk accessible to local-level decision makers. UKRI Participatory Research funding.
Risk-Informed Landslide Management in Nepal's Hill Areas. EU ECHO HIP
Earthquake triggered landsliding in Nepal. NERC / DFID SHEAR

Areas of Interest

Landslide hazard and risk
Participatory mapping
Digital terrain models
