George A. Constantinides
I am Professor of Digital Computation. I lead the Circuits and Systems group at Imperial College where I hold the Royal Academy of Engineering / Imagination Technologies Research Chair. If you would like to contact me, please check this advice.
- In summary, my research interests cover the theory and practice of developing hardware for fast and low power computing, especially for numerical problems. I have active research in computer architecture / custom processor design, synthesis tools, and applications of FPGAs and customised hardware 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, now often referred to as approximate computing in the literature. My other main focus is on customised memory system design and optimisation.
- My research output is widely used in industry. Designs and / or tools based on my work have made it into millions of devices worldwide, as well as tools from leading EDA vendors.
- 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 advise:
- I have also had some great Ph.D. students in the past, who have now graduated:
- I typically also have a group of research staff under my research leadership. Currently this includes:
- Former members of research staff under my management include several of my former PhD students (above) and, in addition:
- I have current academic collaborations internally with:
- Externally, I have active academic collaborations with:
- I have active industrial collaborations with the following companies:
- In 2008 I was a visiting researcher at the Computer Lab in Cambridge (host Simon Moore) and Pembroke College Cambridge (host Jan Maciejowski), where I retain occasional dining rights.
- My Erdos number is 3. Visit AMS to find your Erdos number, or collaboration distance to other mathematicians and computer scientists!

Tools and Benchmarks
Some open-source tools and benchmarks resulting from my research include:
My research, my staff, and my PhD students are funded by:
I have also previously received research funding from:
- I am Technical Program Chair of FPGA in 2014, General Chair in 2015, and Finance Chair in 2016.
- I serve on the programme committees of: ACM/SIGDA International Symposium on Field-Programmable Gate Arrays (FPGA), ARITH, and DAC Designers' Track. In the past I have chaired the FPL (2003) and FPT (2006), ISCAS track (2013), FPGA (2014/2015) and ARC conferences.
- I sit on the International Subgroup of the EPSRC Strategic Advisory Team, after having been a long-serving member of the team itself (2010-2015).
- I am a member of the EPSRC Peer Review College (2006-).
- I am a Fellow of the BCS and a Senior Member of the IEEE.
- My teaching is limited due to the award of a Research Chair. I undertake occassional teaching as interests me.
- I have a strong interest in STEM outreach work with primary schools.
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.
