Contact, Bio, Calendar, Code

My research interests are in User-Centred Systems, IoT, Applied Machine Learning, Privacy, and Human-Data Interaction. At Imperial College, I am part of Imperial-X (I-X). I am a Core member of the Machine Learning Initiative at Imperial, an Academic Fellow of the Data Science Institute and an Associate member of the Academic Centre of Excellence in Cyber Security Research.

I am keen to hear from strong students interested in doing their masters project or PhD research with me, or postdoctoral fellows interested in being hosted at Imperial College London. Please get in touch!

We are always keen to support exceptional candidates for the Imperial College Research Fellowships, the Imperial President’s PhD Scholarships, China Scholarship Council, the Islamic Development Bank – Imperial College Scholarship, UKRI AI for Healthcare CDT, the London Interdisciplinary Social Science Doctoral Training Partnership (LISS DTP), and various other UK and International Scholarships and Centres for Doctoral Training in Imperial College London.

I also supoort exceptional candidates for EU Individual Fellowships (IF) and UKRI EPSRC Postdoctoral and Open Fellowships. Please get in touch to discuss these, sending me any relevant material, information, and a potential proposal idea.

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.
