Dr Bogdan Roman

Picture I have dual affiliation, as a Research Associate at the Applied Maths department working primarily on compressed sensing, and as Research Fellow at the Computer Lab, working on wireless comms. I am also the Director of Studies for Computer Science at Homerton College.

Research and Teaching

I co-lecture a Part III course on Sampling and Compressed Sensing at DAMTP, give a Part II lecture on wireless comms at the CL, and supervise a number of undergraduate courses.

My research interests at the Computer Lab lie in the design, implementation and modelling of cross-layer wireless schemes (with an emphasis on scalability, efficiency and harsh conditions) and Software Defined Radio (SDR) approaches. I am also interested in the usage of multi-carrier systems and OFDM techniques for higher level applications (e.g. contention, cognitive radio, white-spaces), and analysis of randomized algorithms.

Software Defined Radio (SDR)

The wireless system I designed and implemented during my PhD (called Multi-Carrier Burst Contention), has received a Microsoft Research Software Radio Academic Program Award to advance the research into multi-carrier techniques. As a result, we now have several powerful SDR equipment available for research and for Part II and MPhil projects.

Contact me if you are interested in SDR applications or projects (Part II and Mphil welcome).

Probability Questions and Puzzles

I sometimes create and collect probability theory questions and puzzles. They are short, yet not (all) trivial, so I hope you'll find them entertaining. I also use them in my undergraduate teaching so I welcome alternative solutions, extensions or new questions:

During 2006-2010 I was sponsored by Girton College, the Cambridge European Trust, the Cambridge Overseas Trust and also by Felix Telecom Romania.

I'm also the author and webmaster of the Digital Technology Group website.
