Teaching

Undergraduate teaching:

I teach analogue and digital electronics (EN1215/EN1216/EN2178) in the first year to Electronic, Integrated and Medical Engineering students.

Post-Graduate teaching:

I teach CAD and simulation software (ENT672), instrumentation (EN799/EN4089), modelling and measurement of solid state devices (ENT610/EN4910), and high frequency power amplifiers (ENT898) to MSc and MEng students in the areas of Microwave and Wireless, Communication Technologies and Compound Semiconductor Electronics.

I am year tutor for the MSc in these areas.

Biography

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.

I am in the review panels of the European Microwave Conferences, and a regular reviewer for the IEEE Transactions on Microwave Theory and Techniques and the IEEE Microwave and Wireless Components Letters. 

I am the Deputy Chair of the IEEE Microwave Theory and Techniques Society Technical Committe 12 "Microwave high-power techniques", with which I regularly organize workshops and special session at the main conferences in the sector.

Honours and awards

MTT-S 2024 Award for Best Papaer in the IEEE Microwage Magazine

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

MTT-S Member

IET 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.

Supervisions

I currently supervise 8 PhD students as main supervisor in the areas of high frequency power amplifier design, characterisation and modelling. I also co-supervise other students in similar areas.

I am interested in supervising PhD students in the areas of:

  • Power amplifiers design and characterisation
  • Microwave and millimetre-wave non-linear characterisation
  • System level characterisation, modelling and linearisation
