I earned a Bachelor's degree in Computer Engineering followed by an MSc in Data Communication Engineering at the University of Sheffield. Then, I pursued a PhD with a focus on translational digital engineering in chronic conditions to sustain behaviour change. I have had the privilege of holding several postdoctoral research associate roles in the Electronic and Electrical Engineering Department at the University of Sheffield. In these roles, I focused on researching novel statistical, machine learning and AI models and biomarkers. I've also ventured into digital healthcare technology with a mission to make it more inclusive and efficient. I've had the opportunity to collaborate closely with the Royal College of Arts, combining design and technology to create user-friendly healthcare solutions. My emphasis in this endeavour has been on highlighting the potential of digital technologies to enhance care, especially for vulnerable populations. |

My research is primarily focussed on energy efficient communications. This is becoming increasingly important as mobile communications expands, with power consumption of networks rising sharply with the introduction of 5G. I am particularly interested in applying newly mature and emerging electromagnetic technologies, such as metamaterials, in wireless transceivers and mobile networks. This is now an expanding topic in research for 6G mobile, where the ability of metasurfaces to manipulate signals offers new ways of designing communications systems by controlling the propagation environment. These techniques are often referred to as Intelligent Reflecting Surfaces (IRS) or Reconfigurable Intelligent Surfaces (RIS). |
