My main research interests are the analysis of distributed algorithms, and network economics and dynamics. It involves the mathematical analysis of models of large networks that arise in online systems using tools from probability theory and algorithm design. See my papers below for details.



Short Bio


I graduated from the Ecole Polytechnique (Paris) in 2000. I then completed a DEA in Probability Theory at the University Paris VI. I undertook a PhD at the LIAFA (Theoretical Computer Science Group), University Paris VII. 


From October 2004 to January 2007, I was a Marie Curie research fellow at the Statistical Laboratory and a lecturer in Part III (Certificate of Advanced Study in Mathematics), Cambridge University.


Since 2007, I am a Faculty member in the EEE department, Imperial College London.


I spent the first half of 2011 as a visiting researcher to Microsoft Research Cambridge visiting the Networks, Economics and Algorithms group.


In Fall 2014, I will be teaching, with Wei Dai, a course Topics in Large Dimensional Data Processing.



Prospective PhD students


If you enjoy applying a variety of mathematical tools (probability, algorithms, game theory, optimisation and learning theory) to model online systems (e.g., social networks, crowdsourcing, cloud computing), then consider applying to our PhD programme to undertake a PhD with me.

Do not hesitate to contact me for further details.


The college and the EEE department offer a number of funding schemes.


Chinese applicants may want to consider the CSC Imperial scholarships.



Postdoctoral funding


In addition to occasional funding opportunities that are directly funded through research grants, a number of funding schemes are available to undertake postdoctoral research.


EU Marie Curie Fellowships, EPSRC Postdoctoral Fellowships, Royal Academy of Engineering Research Fellowships, Leverhulme Trust Early Career Fellowships, Newton International Fellowships, Imperial College Junior Research Fellowships.


Do not hesitate to get in touch if you are considering to apply for one of the above schemes.
