I am a Reader in Human-Centred Systems and the Director of Postgraduate Studies at the Dyson School of Design Engineering, at the Faculty of Engineering at Imperial College London. I also serve as a Security Science Fellow of the Institute for Security Science and Technology. In my industrial role, I am a Visiting Professor at Brave.
My research interests are in User-Centred Systems, IoT, Applied Machine Learning, Privacy, and Human-Data Interaction. At Imperial College, I lead the Systems and Algorithms Laboratory (SysAL). 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.
