Mounir Laroussi Inventions Information

Mounir Laroussi, is a Tunisian-American scientist. He is known for his work in plasma science, especially low temperature plasmas and their biomedical applications.

Mounir Laroussi was born and raised in Sfax, Tunisia, the son of Habib Laroussi and Manana Jeloul. He is the middle child of three siblings.

Laroussi attended the Alexander Dumas Elementary School and the Lycee Technique de Sfax (middle school and high school). He received his “Diplome d’Ingenieur” from the Ecole Nationale d’Ingenieurs de Sfax (ENIS) and completed his Master’s equivalent thesis in 1981 at the Ecole Nationale Superieure d’ Electronique et de Radioelectricite de Bordeaux (ENSERB) in Bordeaux, France. In 1998, Laroussi received his PhD in electrical engineering from the University of Tennessee.

In 1995, Laroussi joined the Microwave and Plasma Laboratory of the University of Tennessee as a Research Assistant Professor. In 1998, Laroussi joined Old Dominion University as a Research Associate Professor in the Applied Research Center. In 2003, he became an Associate Professor in the Electrical and Computer Engineering Department at Old Dominion. In 2008, Laroussi was appointed Full Professor. He is currently a Professor at the Electrical and Computer Engineering Department of ODU and is the Director of ODU’s Laser and Plasma Engineering Institute (LPEI).

Laroussi's research interests are in the Physical Electronics area, particularly in the applications of non-equilibrium gaseous discharges. Amongst these are the generation of large volume low temperature plasmas, the interaction of microwaves with plasmas, and the biomedical applications of cold plasmas, a field known as “Plasma Medicine”. In the latter, he published seminal papers on the interaction of low temperature plasmas with biological cells. In plasma medicine research, low temperature plasmas (or simply cold plasmas) are used to inactivate bacteria and proteins, assist in wound care, destroy some types of cancer cells, and play an active role in various other medical therapies. In 2009 the Institute of Electric and Electronics Engineers (IEEE) elevated Laroussi to Fellow for his contributions to the biomedical applications of plasmas.

Laroussi’s best known invention is the Plasma Pencil. This device can generate long plumes or jets of cold plasmas that can be used in various biomedical applications, including in dentistry. The Plasma Pencil was the subject of wide media coverage including a mention in an article in National Geographic (February 2006 issue), and ABC online news. It was featured in science/technology shows on the History Channel and the Smithsonian Channel.

Laroussi served as an elected member of the Administrative Committee (2002–2005) and the Plasma Science and Applications Executive Committee (2005–2007) of the IEEE Nuclear and Plasma Sciences Society (NPSS). He has also served as a Guest Editor of the IEEE Transactions on Plasma Science, and of Plasma Processes and Polymers, a Wiley-VCH journal. He serves as an IEEE-NPSS Distinguished Lecturer.

In addition to his scientific work, Laroussi writes short stories and is a soccer player and fan. He is fluent in Arabic, French, and English.
