I graduated with a MPhys (1999) and a PhD (2003) both from the Dept. of Physics at ºù«Ӱҵ. My thesis detailed research into the carrier processes and dynamics in quantum dot lasers.
I joined the EEE Dept in 2003 initially as a postdoctoral researcher investigating quantum dot lasers for telecommunications applications as part of a European project, but soon became involved in developing device fabrication capabilities for a broad range of additional projects including quantum cascade lasers, InP photodiodes, and single photon devices.
In 2005 I was awarded a Royal Academy of Engineering Research Fellowship for research into advanced semiconductor laser engineering, focusing on regrowth technologies for GaAs, including buried self-aligned stripe and distributed feedback (ie. single frequency) lasers, which provided a potential platform for GaAs photonic integration and next generation vertically-emitting lasers.
At the same time, a burgeoning interest in biophotonics research drew me in to investigate GaAs based superluminescent diodes as low coherence light sources for application in optical coherence tomography.
Following the end of my Fellowship I was appointed as Lecturer in 2010, moving to Senior Lecturer in 2012.
My research continues to focus on semiconductor optoelectronic component design and manufacture, with an interest in photonic integration and in the application of near- and mid-IR semiconductor lasers, superluminescent diodes, amplifiers, detectors and passive optical elements for application in high value manufacturing methodologies, such as in additive manufacturing and embeddable metrology.
I am currently working on projects to develop capability for the heterogeneous integration of III-V semiconductor components and circuits upon a range of substrates to enable new sensor technologies, both through the collaborative EPSRC Heteroprint project and via the EPSRC Future Photonics Hub.
At the same time, I am pursuing research into the application of laser diode arrays for efficient high-speed additive manufacturing of both metallic and polymer parts.
