Dr Jayaprasath Elumalai

Profile

I earned a BSc in Physics from Loyola College (Madras University), Chennai, India, in 2008, followed by an MSc in Physics from Pondicherry University, Pondicherry, India, in 2010.

In September 2011, I began my PhD in Physics at Pondicherry University in India. My PhD research focused on chaos synchronisation in diode lasers and the effect of propagation-time delay in coupled complex systems. In October 2016, I received my PhD with a thesis titled ‘Intracavity propagation delay in synchronised chaotic semiconductor diode lasers.’ During my PhD studies, I was awarded a Junior Research Fellowship by the University Grants Commission, Basic Scientific Research division, Govt. of India, from December 2014 to September 2015, and a Senior Research Fellowship by the Council of Scientific and Industrial Research, Govt. of India, from October 2015 to August 2016.

From September 2017 to November 2019, I was a postdoctoral researcher at Southwest University in Chongqing, China, where I worked on the dynamics of vertical-cavity surface-emitting lasers and microwave generation. In December 2019, I moved to the UK to serve as a postdoctoral research officer at the DSP Centre at Bangor University, Wales, a position I held until November 2022. My research during this period focused on physical-layer secure optical transmission systems, various network topologies, and microwave photonics.
