Dr Erasmia Lyka

Erasmia received her M.Eng. degree in electrical and computer engineering with Erasmia Lykahonours from the Aristotle University of Thessaloniki in Greece in 2011. She then completed her M.Sc. degree in biomedical engineering at the University of Oxford in 2012. In 2013, Erasmia started her doctoral studies under the supervision of Prof. Constantin Coussios in BUBBL. Her research was supported by the UK’s Engineering and Physical Sciences Research Council (EPSRC) Departmental (DTA) Studentship, and focused on the development of techniques for improved detection and localization of sources of acoustic activity using Passive Acoustic Mapping. Erasmia successfully defended her DPhil thesis in December 2016, and since then she joined the EPSRC UltraSpine Project as a post-doctoral researcher. Her work is currently focused on delivering high intensity ultrasound to the intervertebral disc using an acoustic array of transducers and beamforming techniques based on time-reversal to induce tissue fractionation for removal of diseased tissue.
