Dr Owen Weller is a Lecturer in the Earth Sciences department at the University of Cambridge. Dr Weller took up this position in 2017, following a research fellowship at the Geological Survey of Canada, where he contributed to developing the first trilingual geological maps (English, French, and Inuktitut) of a remote but resource-rich part of Baffin Island, Arctic Canada (alongside co-Trip Scholar Professor Marc St-Onge).

Dr Weller researches how the paradigm of the Earth Sciences—plate tectonics—has evolved through geological time. This research includes analyzing ancient, eroded mountain belts in the Canadian Arctic and the Scottish Highlands, as well as active mounting building processes in the Himalaya, to understand how the associated driving forces have changed through Earth history. In particular, Dr Weller specializes in interpreting the metamorphic rock record to decode the history of past plate movements, alongside field, petrographic, phase equilibria modelling and geochronological techniques.

Within the Earth Sciences department at Cambridge, Dr Weller teaches a variety of undergraduate courses associated with metamorphic petrology, and contributes to several field trips, including leading the second-year field trip to Cornwall.
