Basics
I am a Reader (Associate Professor) in Digital Systems. I work in the Circuits and Systems group at Imperial College. My office is Room 912 of the Electrical and Electronic Engineering Department.
Research
- In summary, my research interests cover the theory and practice of using hardware to implement fast algorithms, especially numerical algorithms. I have active research in the architectures, synthesis tools, and applications of reconfigurable hardware (FPGAs) for this purpose. I coined the term "lossy synthesis" to describe circuit synthesis techniques allowing a controlled tradeoff between quality, typically numerical accuracy, and traditional metrics such as area and power. Much of my EDA work retains a focus on lossy techniques.
- The best detailed view of my research is from my publications. I suggest you look at my (incomplete) repository, at Google Scholar, or the DBLP server, but remember they all have a certain time lag. If you want the PDF of one of my papers, please ask.
- I am fortunate to have an excellent group of Ph.D. students. I am primary supervisor for Sam Bayliss, Theo Drane, Juan Jerez-Fullana, Abid Rafique and Kan Shi. I am also secondary supervisor for Zhenyu Guan and Josh Levine.
- I have also had some great Ph.D. students in the past, who have now graduated:
Dr Su-Shin Ang (now with Toumaz Technology), Dr David Boland (still at Imperial, as a member of research staff), Dr Nick Campregher (now with Standard Bank), Dr Jonathan Clarke (now with e-ip), Dr Chun-Te Ewe (now at Deloitte), Dr Ammar Hasan (now Assistant Professor in Pakistan), Dr Asma Kahoul (now with Goldman Sachs), Dr Qiang Liu (now Associate Professor, Tianjin University, China), Dr Gareth Morris (now with Celoxica), Dr Antonio Roldao Lopes (now with Morgan Stanley), Chalermpol Saiprasert (now with NECTEC, Thailand), Dr Kwang-Hwee Seah (now with I2R, Singapore), Dr Nalin Sidahao (now Assistant Professor at Mahanakorn University of Technology), Dr Al Smith (now at PA Consulting), Dr Pete Sedcole (now at Cambridge Silicon Radio), Amir Shahzad (now back in Pakistan), and Dr Kieron Turkington (now at Altera).
- I typically also have a small group of research staff under my research leadership. Currently this includes Mr Sam Bayliss, Dr David Boland, Dr Andrea Suardi, and Dr Sujit Bhattacharya. In the past, Dr Antonio Roldao Lopes (now with JP Morgan), Dr Al Smith (now with PA Consulting), Dr Dom Buchstaller (now with Siemens Research), Dr Peter Jamieson (now Assistant Prof at Miami University), Dr Altaf Abdul Gaffar (now with Islamic Development Bank), Stefano Longo (now Lecturer at Cranfield University), Mr Markos Papadonikolakis (now at Altera), and Dr Pete Sedcole (now with Cambridge Silicon Radio) also used to work on my projects. I am the sponsor of Junior Research Fellow Dr Nachiket Kapre.
- I have current academic collaborations internally with Prof Peter Cheung, Prof Wayne Luk, Prof Paul Kelly, Dr Eric Kerrigan, Dr Christos Bouganis, and externally with Prof Jan Maciejowski, Prof Ling Keck Voon, Katholieke Universiteit Leueven, ETH Zurich, Karlsruher Institut fuer Technologie, Technische Universiteit Delft, University of Heidelberg, Technische Universitaet Dortmund, INESC-ID, Universade do Porto, and University Polithnica Bucharest. In the past, I have also had external collaborations with Dr John Brooke, Dr Michael Chia, and Prof Mike Giles, and Prof Stan Scott.
- I have current industrial collaborations with Altera, ARM, Associated Compiler Experts, BASF, Coreworks, the European Space Agency, IPCOS, Imagination Technologies, LMS International, The Mathworks, Microsoft, and Xilinx. In the past I have also collaborated with Synplicity (now part of Synopsys), Celoxica, and Agility Design Solutions (now part of Mentor Graphics).
- From January to June 2008, I was on sabbatical leave in Cambridge, and a Visiting Scholar of Pembroke College, where I was based with Simon Moore, and Jan Maciejowski. I now have Long Term Visitor status at the University of Cambridge Computer Laboratory and occasional dining rights at Pembroke.

A note to prospective postgraduate students
I welcome applications for postgraduate study. Please note the following points:
- Applications for PhD places are very competitive. Unless you have a 1st class first degree or a 2/1 first degree + a 1st class project, it is unlikely that you will be accepted by our group. MEng or BEng + MSc is preferable to BEng only.
- If you have a BSc or a BEng from outside Imperial College, my advice is usually to apply for the MSc in Analogue and Digital IC Design or one of the other MScs offered by our department before considering an application for a PhD.
- If you are a home (UK) or EU student, funding opportunities are available - please contact me to discuss them. If you are an overseas student, unfortunately funding opportunities are far more limited: please read the IC Registry website - look under scholarships. There may be further departmental funding available for exceptional overseas students, but unless you have published well in international conferences or journals, it is unlikely that your application will be competitive.
- Please note that I do not usually take Summer interns from outside Imperial College, and I receive such a large number of such requests that I cannot reply to every one - I apologise for this.
Non-Professional Activities
- I like food. I love Munich.
- I am an espresso geek. I use a Gaggia Classic at home, a Krups Nespresso Le Cube at work, and a Handpresso when I am out and about. I have my eye on an Elektra Micro Casa a Leva, but I cannot bring myself to part with the money.
- I like mountains, especially the Austrian Tyrol, and most especially the village of Obergurgl.
