Biography

I received my BSc degree in electromechanical engineering from the University of Resita, Romania in 1995, and my MSc and PhD degrees in electrical engineering from 'Politehnica' University of Timisoara, Romania in 1996 and 2001 respectively.

From 1996 to 1999, I was with Bee Speed, Timisoara, Romania (full time and part time), involved in the design, execution, commissioning and maintenance of electrical equipment based on power converters, where I acquired valuable practical industrial experience.

Between 1998 and 2000 I was for a total of 14 months a Guest Researcher at the Institute of Energy Technology, Aalborg University, Denmark, where I was working with matrix converters, in conjunction with my PhD thesis, under the auspices of the Danfoss Professor Programme.

From 2001 to 2003 I was a Research Assistant Professor at the same Institute, continuing the research work in direct power conversion under the auspices of the Innovation Post-Doc programme supported by the Danish Research Agency and Danfoss Drives A/S.

As of October 2003, I am a lecturer at the School of Electrical and Electronic Engineering, University of Nottingham, UK, teaching Power Electronics Design (H63PED/H5DPE2) and partly, Power Quality. I am also supervising undergraduate student projects related to general electrical engineering with focus on power electronics, electrical drives, power quality, renewable energy. I am also supervising postgraduate (MSc and PhD) and research projects related to desing, control and evaluation of novel/advanced power electronic converter topologies.
