Petru-Edward Nica graduated in 1996 the Faculty of Physics, “Al. I. Cuza” University of Iași, Romania at Solid State Physics Division and he obtained his Ph.D. in 2004 at the same institution in the field of Electromagnetic phenomena physics. 

Between 2004 and 2006 he was employed as Postdoctoral researcher at Laboratory of Advanced Science and Technology for Industry, University of Hyogo, Japan, working in the development of new soft X-ray sources based on laser produced plasma (LPP) for the present generation of semiconductor lithography. During the past ten years, his scientific activity is mainly in the field of LPP, being focused on the following subjects: i) Theoretical and experimental studies of plasma produced by femtosecond laser ablation using various targets – atomic mass dependence of ablation plasma oscillations; ii) Analytical and numerical description of hydrodynamic processes during plasma expansion – local fluctuations of plasma parameters; iii) Analytical interpretation of Langmuir probe characteristics and currents recorded by charge collectors through fundamental ionization – recombination processes (local thermal equilibrium model, stationary and non-stationary collisional-radiative model); analysis of the multi-peak structures of the ionic current; iv) Investigations of new methods for determining the plasma parameters (electronic temperature and number density, charge state distribution) and v) Building new laser ablation models based on the scale-relativity theory and fractal space-time hypothesis. During his activity he published more than 60 papers in Thomson ISI journals, having in 2018 the Hirsch index of 13.

  In present, Petru-Edward Nica is working as Professor at “Gheorghe Asachi” Technical University of Iași, where he is the Director of Physics Department.
