Ananya Renuka Balakrishna

I am a third year PhD student at University of Oxford. I work in Solid Mechanics and Materials research group under the supervision of Prof. John Huber.

My research focusses on modelling a set of "smart" materials called the ferroelectrics. These materials possess immense potential as memory elements, transducers and energy harvesters. I have designed nanoscale devices such as actuators with enhanced performance (larger strains) using a phase-field model and am currently studying size effect on in nanoscale ferroelectrics.
