PhD student

My research focuses on the application of tephrostratigraphy in identifying and tracing the deposits of explosive eruptions in the East African Rift Valley. Specifically, I focus on the identification of distal tephra in lake records.

Research

Tephrostratigraphy is the study of strata composed of volcanic ash (tephra) and various other deposits, their superpositions and how they are distributed across a landscape. It is a tool used to understand the characteristics and frequencies of historic, explosive eruptions prior to written records, thus has applications in present day hazard management.

However, tephrostratigraphy has a wider interdisciplinary scope, and also provides a method of dating and correlating palaeoenvironmental or archaeological sequences. The proximal and distal deposits of a single eruption represent a geologically instantaneous event and have a unique geochemical fingerprint which can be traced between archives.

My research focuses on building tephrostratigraphic frameworks for the East African Rift Valley, with a specific focus on identifying distal tephra layers in lake sediment records and correlating these across Kenya and Tanzania.
