In 1977 he graduated from Technical University of Timisoara as a chemical engineer. He received his PhD degree in chemical engineering in 1994, under the supervision of the distinguished Professor Liviu Oniciu. As Teaching Assistant (1987), Assistant Professor (1990), Associate Professor (2000) and Professor (2005) at the Faculty of Chemistry and Chemical Engineering Cluj-Napoca, Petru Ilea introduced and developed the electrochemical engineering and electrochemical technology programs in the undergraduate and graduate curricula at our faculty. His courses were appreciated by both undergraduate and graduate students. He focused his research efforts in the domains of electrochemical engineering and technology. At the same time, the environmental applications of electrochemistry were among the most fruitful scientific preoccupations of Professor Petru Ilea. In addition to over 80 scientific papers, Professor Petru Ilea also co- authored 3 books and managed numerous grants and research projects. He counts more than 110 participations to scientific conferences with lectures, posters and oral communications. The research grants he coordinated, substantially contributed to the development of electrochemical engineering and technology at “Babeş-Bolyai” University.
