Roles

Wajdi Abdulaziz Gaddah is a faculty member in the Department of Physics at the Faculty of Science. After earning his Master’s degree with distinction from the University of Tripoli in 1993 (in the field of Nuclear Physics), he worked at the Technical Research Center (Laser Department) and then at the University of Tripoli. He later pursued further studies at Durham University in the UK, where he obtained his PhD in 2002 in both Particle Physics and Mathematical Physics. During his time at Durham University, he worked as a part-time teaching assistant for nearly two years, and after completing his doctorate, he continued as a visiting researcher at the same university for a few months. 

Currently, he holds the position of Assistant Professor in the Department of Physics, where he is actively involved in both scientific research and teaching at the undergraduate and graduate levels. He has several international publications to his name, focusing on quantum physics, which represents his primary scientific interest.

Careers

·         Since May 2007 to present, I have been working as a full-time faculty member in the department of physics at the University of Tripoli. I have taught a number of lecture courses at the lower and upper undergraduate levels such as: General Physics, Physics Lab Experiments (1st-year level), Intermediate Classical Mechanics, Analytical Mechanics, Quantum Mechanics I and II. Moreover, I have contributed effectively to the MSc graduate teaching program.

·         From 9th August 2004 to May 2007, I held the position of a full-time faculty member in the physics department at the University of Al-Jafara (Libya), which was fully integrated into the University of Tripoli in 2005. During this time, I taught several undergraduate courses such as: General Physics, Classical Mechanics, Quantum Mechanics, and Mathematical Physics.

·         In spring 2004, I worked as a part-time lecturer in a private college, Al-Quds College in Tripoli, Libya. I taught Calculus I and II to the undergraduate engineering students.

·    From Oct. 1999 till June 2001, I worked as a part-time teaching assistant (TA) in the Department of Mathematical Sciences at Durham University in England. My duties included marking and invigilating examinations, grading weekly assignment, giving pedagogical feedback and tutorials to undergraduate students in the following courses:

1.      Single Mathematics A (MATH 1561): Linear algebra, calculus, complex numbers, matrices and numerical methods.

2.      Single Mathematics B (MATH 1571): Vector algebra, ordinary differential equation, Fourier analysis, partial differential equations with applications to physical problems, functions of several variables.

 ·         From 1994 till April 1995, I worked as a junior faculty member in the department of physics at the University of Tripoli. During this period, I taught a general physics course (PH112) to undergraduate students, using the standard textbook “Physics by Halliday and Resnick”. Besides, I gave numerous tutorial classes and contributed to the marking duties.

·         From Aug. 1993 till Dec. 1993, I worked with the laser research group at the Technology Research Centre in Tripoli as a research physicist.        

Research Interests

My research primarily focuses on the application of advanced mathematical methods to solve complex quantum mechanical problems, with a particular interest in quantum field theory and quantum scattering theory.

I have worked extensively on obtaining exact solutions to the Dirac equation, including solutions for quantum billiard systems using symmetry group transformations. This work also extends to exploring discrete symmetry approaches, where I successfully derived exact bound-state solutions for a regular hexagon Dirac billiard.

Recently, I completed a new research project that applies high-order Bender-Wu perturbation theory to solve the Dirac oscillator problem in a sextic anharmonic double-well potential, pushing the boundaries of perturbative methods in quantum mechanics.

Through these works, I aim to deepen the understanding of quantum systems using symmetry principles and perturbation techniques, while continuing to explore the mathematical frameworks underpinning quantum field and scattering theories.

External Activities
