The University of British Columbia

Activities between the University of British Columbia and Exeter include a joint research symposium focused on Community, Culture, Creativity, and Wellbeing held at Exeter in May 2018 and a faculty-led, co-funded initiatives in Sport, Exercise and Health Sciences, Climate Change and Digital Humanities.

University of South Florida

University of South Florida and Exeter have entered into a 5 year student exchange between the two Universities. They launched the University of Exeter / University of South Florida Research Catalyst Fund to provide grants to support joint research initiatives between the two institutions.

Tsinghua University

The University of Exeter and Tsinghua University have launched a jointly-awarded PhD degree programme in climate and environmental sciences which supports six students to be co-supervised between Tsinghua's Department of Earth System Science and Colleges at Exeter that conduct research on earth systems and environmental sciences.

Nanyang Technological University

NTU and Exeter are working in partnership to deliver six split-site Biomedical PhD studentships. If successful, you will benefit from expert supervision from researchers in both institutions and have the opportunity to research and live in two great locations, for up to eighteen months in each.

University of Geneva

To celebrate, and further extend, the strong relationship of staff within the University of Exeter and the University of Geneva, the two universities have launched a new seed fund to support developing research links.

University of Queensland

The University of Exeter and The University of Queensland have partnered to establish the QUEX Institute, a new multi-million pound partnership designed to bolster their joint global research impact. Read more.

Laver Building Level 7

Laver Building, University of Exeter, North Park Road, Exeter, EX4 4QE, UK

Overview

Rayanne graduated from the University of Exeter in 2018 with an MMath in Mathematics, specialising in applying mathematics to Earth system science. During her final year, Rayanne developed a particular interest in Earth and climate system modelling, collaborating with the Met Office to help improve vegetation dynamics within the Joint UK Land Environment Simulator model (JULES).

Since then, she has joined the WildFIRE lab as a PhD student to investigate Earth system feedbacks and the history of Oxygen. In particular, using models to investigate the role in which fire has played in keeping Oxygen levels relatively constant over time.

Broad research specialisms:

Earth system and climate modelling, Earth system feedbacks, Mathematics of the Earth system

Qualifications

MMath (Hons) Mathematics
