My research focuses on understanding and extending instrumentation hardware performance limits, including signal integrity, hardware signal processing and novel device technologies.

My group currently works on memristor modelling, the use of memristors in random number generators and stochastic computing gates, and multiunit/cell ReRAM.

In the past we have studied signal integrity, including slow surface wave propagation and substrate crosstalk and coupling on multilayered conductive substrates. Our work on novel devices includes SiGe devices and circuits, RF MEMS, slow wave filters and more recently memristors. Finally, we have worked on novel data acquisition techniques including asynchronous sigma-delta modulation and spread spectrum modulated amplifiers.

Before coming to Imperial I worked on GaAs monolithic microwave integrated circuit design and technology and also on fundamental electron physics at low temperatures.

I serve on several IEEE Circuits and Systems Society Conferences Technical Program Committees and review for a number of IET and IEEE journals. I am a visitor at the National Centre for Scientific Research in Athens.

I am a Senior Member of IEEE and Member of IET.
