Rhiannon Heard MEng

DPhil Researcher

Stipendiary Lecturer in Engineering

Trinity College Junior Dean

Biography

Rhiannon studied Engineering Science at University of Oxford for her undergraduate degree, for which she was in receipt of the IMechE Spen King Sustainability Award 2013 and the IET Diamond Jubilee Scholarship. During her undergraduate degree, Rhiannon worked on a number of summer projects at Jaguar Land Rover with a focus on materials development and sustainability.

In 2017, Rhiannon completed her Master’s specialising in mechanical and materials engineering, and was given the opportunity to remain in the Solid Mechanics group at Oxford to take up her current DPhil position.

Rhiannon’s doctoral project, funded by EPSRC and in collaboration with Deben UK Ltd, focusses on development of new technologies for studying material behaviour in situ SEM at elevated temperatures.

She is also currently a Junior Dean and a Stipendiary Lecturer in Engineering Science at Trinity College.
