Available for postgraduate supervision


I am a Lecturer in the School of Engineering. My research focusses on high frequency power amplifiers.

I have published around 80 peer-reviewed scientific papers, of which more than 25 on international scientific journals. I am co-author of the books "Electronics for Microwave Backhaul" and "Telecommunication Electronics" published by Artech House.

I am year tutor for the MSc courses related to Microwave and Wireless technologies.

I teach master-level modules on advanced microwave techniques, and undergraduate modules on Analogue and Digital Electronics.


I graduated cum laude in Electronic Engineering from Politecnico di Torino in 2008.

I obtained my PhD from Politecnico di Torino, Italy, in 2012, where I have been working on power amplifier design, characterization and linearization.

From 2012 to 2014 I have been a Post-Doc fellow at Politecnico di Torino.

In 2015 I joined Huawei Technologies, where I designed millimetre-wave components for 5G prototypes.

I started my position at Cardiff University in September 2015 with a MSCA Fellowship from the European Union. The 2-year project PADWIC treated theory and techniques in power amplifier design for high frequency telecom applications, based on hybrid and integrated technologies.

In February 2017 I have been appointed as a Lecturer at the Schoool of Engineering of Cardiff University, a role that I started in September 2017.

Honours and awards

2009 Young Graduated Research Fellowship presented by the GAAS Association.

2015 Individual Fellowship supported by the European Union in the Marie Sklodowska Curie scheme

Professional memberships

IEEE Member

Committees and reviewing

I am an elected member of the IEEE MTT Technical Committee MTT-5 MICROWAVE HIGH-POWER TECHNIQUES

I am a reviewer for the EPSRC. 

I am a reviewer for the IEEE Transaction on Microwave Theory and Techniques and the IEEE Microwave and Wireless Components Letters. I am in the reviweing board for the European Microwave Week.














Undergraduate teaching:

I teach analogue and digital electronics in the first year to Electronic, Integrated and Medical Engineering students.

Post-Graduate teaching:

I teach CAD and simulation software, instrumentation, modelling and measurement of solid state devices, and non-linear electronics to MsC students in the areas of Microwave and Wireless, Communication Technologies and Compound Semiconductor Electronics.

I am year tutor for the MsC in these area.
