I am a part-time professional law teacher at Cardiff University. I qualified as a Solicitor in 2001 and work full-time as a Partner at Blake Morgan LLP, a full service law firm, based in Cardiff. I specialise in Construction and Engineering law and have particular expertise in a field of alternative dispute resolution commonly used in construction contracts (Adjudication). I am a member of the Technology and Construction Solicitors Association (TeCSA) and the Adjudication Society. I am a Regional Representative for the Society of Construction Law. I was appointed to the RIBA's Professional Conduct Panel in 2016.


I was born and grew up in Leicester.

I studied law at Cardiff University at undergraudate level and also obtained my Postgraduate Diploma in Law (LPC) at Cardiff University. I have a Postgraduate Certificate in Construction Adjudication from Kings College, London.

I qualified as a Solicitor in 2001, having first completed a two-year training contract with a law firm (Morgan Cole).
