About Me

Geologist, educator, photographer, first aider, leathercrafter… I am a person of diverse interests and expertise. I am a Postdoctoral Researcher at Johannes Gutenberg–Universität Mainz.

Primarily, I am a geologist who specialises in the tectonics of subduction zones and large fault zones. My research is focussed on understanding how the physical heterogeneity of rocks in large-scale fault and subduction systems influences the wider-scale tectonics and hazards. I take a highly holistic and multidisciplinary approach to my research, integrating field-based structural geology with petrology, rock mechanics, photogrammetry, and numerical modelling.

I also love to teach and I am interested in innovative and engaging methods of teaching earth sciences, both in the classroom and in the field. I am particularly interested in the opportunities and challenges presented by new technologies and how to balance teaching the traditional fundamentals with preparing students for the realities of modern geoscience.

My photography reflects my love of nature and the diverse forms nature can take. I therefore mainly photograph landscapes, rocks, flowers, insects, and wildlife. I aim to show with my photography the details and wonder hidden in our natural world. As a field geologist, my eyes are trained to notice subtle details in our natural environment and I try to share that experience through my photography.

In my remaining time, I volunteer as an Advanced First Aider for St John Ambulance and am a hobbyist leathercrafter.
