Research Interests

Interests include the design, fabrication and characterisation of optoelectronic devices. Current research topics include quantum dot lasers , high power emitters for photodynamic therapy and the physics of InGaN light emitting devices. I am also interested in optoelectronic integration of materials and functions (see Functional Material and Integration). This involves the exploration of the physics of the light matter interactions in these materials and devices.

Measures of Esteem

Conference Organisation: I currently Co-Chair the Novel-In-Plane Lasers Conference, Photonics West, San Francisco. I was general co-chair for CLEO Science and Innovation 2015, San Jose, having been program co-chair in 2013 and chair of the semiconductor laser subcommittee for CLEO 2010 and 2011. I am a voting member of CLEO steering. I served as general chair for the 2014 International Semiconductor Laser conference held in Palma, Mallorca and was program chair for the 2012 ISLC held in San Diego.

I am also involved in the organisation of a number of other UK based meetings, workshops and conferences including the annual meeting UK Semiconductors and Semiconductor Integrated Optoelectronics, which has been held in Cardiff since 1986. I serve on the program committees of a number of additional international conferences such as CLEO Pacific Rim and the International Photonics Conference (IPC).

I am a member of the editorial board of IOP Semiconductor Science and Technology and IET-Optoelectronics and have edited 2 special issues of the IEE Proceedings - Optoelectronics on Semiconductor Optoelectronics in 2001 and 2006, 3 special issues of IET - Optoelectronics in 2007, 2008 and 2009, co-edited an issue of IEEE Journal of Selected Topics in Quantum Electronics on "Solid State Lighting" in 2009 and co-edited SPIE vols 6909, 7230, 7616, 7953, 8277, 8640 and 9002 on "Novel In-Plane Semiconductor Lasers" in 2008-2014.
