Extended Biography

I studied for my PhD between Oct 2004-Oct 2008, investigating the Topological Characteristics of IP Networks, which I successfully defended on 31st October 2008. My examiners were George Pavlou and Christos Gkantsidis. I carried out my thesis research jointly between two great labs, the NetOS Group, Computer Laboratory, Cambridge University (userid: hh318), and Networks and Services Research Laboratory Group, UCL (supervised by: Miguel Rio, Andrew Moore , Richard Mortier)

I was also a scholar at London Business School, under the UCL CSEL sponsorship programme, attending MBA electives.

My MPhil (transfer) Thesis investigated Network Traffic Inference Using Sampled Statistics [pdf].
In 2004 I completed the MSc in Telecommunication Engineering with distinction. I was sponsored by EPSRC, Project: kOS “kind of Operating System” (report). This work had contributions to technology spin-out Senceive.

Between 1999-2003 I studied for the BEng (Hons) Electronic & Electrical Engineering at UCL. My 2nd & final year were sponsored by Sony Europe. For my final year project I built a stand-alone RDS Encoder (report).

Before that, I studied for A-Levels at William Morris Academy.
