Biography
Dr. Iulian Ionita is a member of the faculty of physics at the University of Bucharest, where he has been a lecturing professor since 1991 and is currently the director of the Research Center in Photonics–Spectroscopy–Plasma–Lasers. Dr. Ionita earned his PhD in physics, specializing in optics–spectroscopy–lasers, from the University of Bucharest. He has published (as author or coauthor) 37 articles related to either biophotonics or spectral characterization of both inorganic materials and human tissues. He is also the coauthor of textbooks on condensed matter spectroscopy, optics, and applied spectroscopy for undergraduate and graduate students.
