Short history: I was born in Romania some (longer and longer) time ago. I have graduated from the University of Bucharest in 1996 (Bachelor's Degree), when I obtained a position in the National Institute for Physics and Nuclear Engineering (Bucharest-Magurele). Same year I was admitted in the Master program at the University of Bucharest. In 1997 I received the Master's Degree, and in January 1999 I have joined the Ph. D. program in the physics department at LSU. I have graduated from LSU in August 2003 (link to my Dissertation).

Research interests: INuclear structure, namely testing approximative methods for evaluating binding energies for nuclides throughout the periodic table. My dissertation research (adviser Dr. Calvin W. Johnson) concentrated in testing the Mean Field corrected by Random Phase Approximation results for binding energies, scalar observables and transition strengths against exact Shell Model calculations. At the University of Arizona my task is to implement the Lee-Suzuki procedure for calculating the effective operators, essential for testing the nuclear wave functions obtained from no-core shell model calculations.
