Personal statement

My areas of activities are centered around heterogeneous integration, micro-fabrication with specific focus in Gallium Nitride light-emitting diodes and photonic integrated circuits, optical characterization, organic and colloidal semiconductors. Each of these areas is evidenced by my publication track record in peer-reviewed journals.
Specifically, I have developed a number of novel micro-fabrication processes, for example the design and build of a custom laser and LED direct write lithography tools or the full design and implementation of custom transfer printing tools; the latter with added capabilities such as full deterministic alignment capability, improved motion system and computer-controlled alignment processes.
In addition, I contributed to the development of LED color conversion and lasers devices using organic semiconductor (OLED) materials and colloidal quantum dots. It included the fabrication, measurement and application of these devices in visible light communication for example. It also encompassed the demonstration of novel formats such as arrays of mechanically flexible lasers with emission over the visible spectral range for applications in bio-sensing.

The research themes selected for the programme featured internationally leading groups at Strathclyde that are well supported by the EPSRC. Each theme is headed by a recognised pioneer in their field supported by a number of associated world class researchers. The five thematic areas were: Photonics, Power & Energy, Advanced Engineering; Advanced Manufacturing, and Bionanotechnology.

Strathclyde identified key international partners at various institutions in the USA and Asia with whom we wished to develop more strategic, mutually beneficial, relationships. We adopted a “best with best” approach, identifying internationally leading researchers who aligned well with several of our own EPSRC funded internationally leading experts. Existing interactions with the groups in the USA and Asia were at different stages of development so we aimed to escalate the relationship engagement levels from Tier 3 (Emergent), through Tier 2 (Developing) to Tier 1 (Strategic). The intention was to develop as many of the relationships as possible during the period of the award so that longer-term interactions could be established thereafter.; 01-Jan-2012 - 31-Jan-2013
