Biography

I received my BSc degree in electromechanical engineering from the University of Resita, Romania in 1995, and my MSc in Power Electronics and Drives 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.

In October 2003 I became a Lecturer in Power Electronics at the Department of Electrical and Electronic Engineering, University of Nottingham, UK. In 2010 I was promoted to Associate Professor in the same Department.

I am member of the Power Electronics, Machines and Control (PEMC) research group, the largest in the Research Division of Electrical Systems and Optics. I am involved in the supervision of postgraduate (MSc and PhD) students and research projects related to design, control and evaluation of novel/advanced power electronic converter topologies for various applications where fast control of power and/or high conversion efficiency is essential.

Expertise Summary

Power electronics and AC drives (in general), direct power conversion (matrix converters), integrated motor-converter drives, grid-friendly power converters for connecting renewable resources (fuel cells, photovoltaic) or novel energy storage devices (supercapatteries) to the AC grid, PWM active front end rectifiers, hybrid power electronic converters.

I have published 100+ papers (37 as first author) in international conferences and 20+ papers in international journals with peer review (13 as first author).

Teaching Summary

I am involved in the teaching of the following modules: Electronic Construction Project (H62ECP), Technologies for Wind Generation (H64TWG) and the Energy Storage (H64ESN) .

I am supervising undergraduate and MSc student projects related to general electrical engineering with focus on power electronics, electrical drives, power quality, renewable energy, energy storage.

I am also the Science without Borders tutor for the EEE department.
