May 2013 -- present

My current research is broadly in the area of trust, privacy and security. Having finished my post-doctoral position in March 2013, I am currently working at the Information Security Group of KDDI R&D Laboratories Inc., based in Japan. I also have active research collaborations with people at the University of Sussex (UK), University of Ontario Institute of Technology (Canada), Rutgers (USA), Victoria University (Australia), Nanyang Technological University (Singapore) and British Telecom (UK).

January 2010 -- March 2013

As a post-doctoral Research Fellow at Tokai University in Japan, I worked in the area of trust, privacy and security. In particular, I worked for a Japanese Ministry of Internal Affairs and Communications funded project on the development of privacy preserving technologies for data on cloud computing. Project partners are Waseda University, Hitachi, NEC and KDDI. I have also been a Visiting Research Fellow at the University of Sussex in the UK since 2010.

In addition to this, I sometimes work with some mini research projects. Please see more details here.

October 2005 -- January 2010

For my doctoral (PhD) research, I have worked on developing a reputation framework based on behavioural history of network clients, which can be used as means to control service levels to protect network services from abuses and unsolicited communication. I have successfully defended my thesis on January 29, 2010 and have been officially awarded the degree on February 15, 2010.

October 2008 -- September 2009

I have worked as a Research Fellow on a £1 million EPSRC funded project to investigate means of supporting shy users in pervasive computing - Shyness.

October 2006 -- September 2009

I have been involved with a £1.4 million EPSRC funded project on trust in pervasive computing - Utiforo.

October 2005 -- July 2006

I have been worked, in collaboration with other researchers, on surveying peer-to-peer network simulators.

July 2003 -- September 2005

I have past research experience in software development for digital cultural heritage applications.

I was working in a €2.8 million EU IST Framework Programme V funded digital cultural heritage project - Augmented Representation of Cultural Objects (ARCO) - and its lightweight prototype (ARCOLite) between July 2003 and September 2005. ARCO was aimed at providing museums with useful technologies for digitising, managing and presenting virtual museum artefacts in virtual cultural environments. Two years after the project started, it became apparent to the designers of ARCO that the total cost of ownership of ARCO was too high for certain smaller heritage institutions due to licensing of components such as Oracle and X-VRML. For this reason, a lightweight digital cultural heritage prototype (called ARCOLite) having similar functionalities was developed primarily as my undergraduate final year project. Further to that, a portable version of ARCOLite was also developed which could run off a CD-ROM. This was developed for educational purposes.
