Kristian graduated with an MPhys (1999) and a PhD (2003) both from the Dept. of Physics at The University of Sheffield. His research focuses 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.
He is 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, he is pursuing research into the application of laser diode arrays for efficient high-speed additive manufacturing of both metallic and polymer parts.
