- Profile
-
Thomas graduated in Environmental Geoscience (MSci) from The University of Bristol in 2014, before carrying out a research placement in volcanology at Colima de Intercambio en Investigación en Vulcanología, Mexico. He joined The University of Sheffield in 2015, where he completed a PhD on the development of low-cost remote sensing instruments for application in volcano monitoring. He subsequently completed post-doctoral research and a Leverhulme Early Career Fellowship at Sheffield, focussing on wider dissemination of permanent SO2 cameras and their use in volcanology.
In 2023 he became a Lecturer in Volcanology at the University. His research interests span volcanology, remote sensing, and the use of machine learning within these fields. He has led the development of a software library, PyCamPermanent, for SO2 camera control and data processing, which is used by a number of researchers and monitoring organisations around the world.
- Research interests
-
I began my academic career as a geoscientist but through my PhD I have developed further skills and interests in software engineering (predominantly in Python), instrument design and optical design. My work therefore spans a broad range of fields, with the overarching focus on using remote sensing techniques to improve our understanding of volcanic activity.

- Teaching activities
-
I have taught on a range of modules during my time at Sheffield. As a graduate teaching assistant I acquired experience marking and providing lab- and desk-based teaching assistance, as well as fieldwork assistance. Now, as an active member of the department’s teaching team, I am involved in course delivery and content design.
