Weaam Alkhaldi received his B.Sc. degree in Electrical and Electronics Engineering in 1997 from University of Garyounis, Benghazi, Libya, and the M.Sc. degree in Electronics and Communications Engineering in 2002 from the Arab Academy for Science and Technology, Alexandria, Egypt. From 2002 to 2003, he was a teaching assistant in the Electronics and Communications Engineering department at the Arab Academy for Science and Technology, and from 2003 to 2005, he was a lecturer in the Electrical Engineering department at the Islamic University of Gaza, Gaza, Palestine. In 2005, he awarded a DAAD scholarship to pursue a Dr.-Ing. degree in Germany. In May 2006, he started working on his doctorate in the Signal Processing Group.

In June 2010, Weaam Alkhaldi finished his PhD with “summa cum laude” for his thesis “Statistical Signal and Image Processing Techniques in Corneal Modeling”.
