I graduated with a BSc in Physics from the University of Sheffield in 2009 and continued in Sheffield to gain my Ph.D. in Electronic and Electrical Engineering developing novel III-nitride/organic hybrid LEDs. I joined the department of Electronic and Electrical Engineering as a postdoctoral research fellow to strengthen the growing III-nitride activity within the university and was appointed to my current position as lecturer in GaN materials and Devices in 2015.

My research is focused on fabricating and characterizing novel semiconductor materials and devices for future optoelectronics such as LEDs, lasers, sensors and displays. In particular, I have a strong interest in developing new additive manufacturing fabrication techniques, allowing the manufacture of new types of semiconductor devices, or devices in new application areas. By utilising these additive manufacturing techniques it is possible to combine different semiconductor materials such as III-nitrides, organic semiconductors and colloidal semiconductor quantum dots into novel devices, combining the strengths and mitigating the weaknesses of each individual material.

I am currently working on utilising transfer printing processes to fabricate hybrid LEDs and lasers that exploit strong coupling effects in optical microcavities to enable higher efficiency light emitting optoelectronic devices emitting across the full visible spectrum. I am also investigating employing non-standard epitaxy processes such as sputtering to grow III-nitride semiconductor materials such as AlN, AlInN and BN.
