Essential Bio: 

I am a Phd student in the MAMA program. I have done my bachelor in telecommunications engineering at An-Najah university in Nablus, Palestine. Then I have joined Erasmus joint master program called MathMods (Mathematical Modelling in Engineering) where I have studied in two universities which are University of L'Aquila in Italy and University of Hamburg in Germany. I have done my master thesis under the supervision of Professor Gianluigi Rozza with Dr Andrea Mola and Dr Giovanni Stabile as co-adivsors. My thesis title was Reduced order methods for computational fluid dynamics parametric problems with finite volumes discretization. In my thesis work we have dealt with the problem of flow around circular cylinder as a FSI problem with many interesting features from both the physical and mathematical point view.

During my PhD studies, I have done several courses in the first year in applied mathematics and scientific computing. I have also carried research activities under the supervision of Prof. Gianluigi Rozza in mathLab research group. My research work was in the field of numerical analysis and computational mathematics. In particular, I worked in the field of reduced order modelling and its applications in computational fluid dynamics.

In my PhD research work, we worked on developing reduced order methods for problems in fluid dynamics discretised using the finite volume method. We also studied the reduction techniques for turbulent flows. In the course of my research work, we have submitted several contributions to journals and conferences proceedings. These contributions focused on novel reduced order methods for problems of the interest of scientific community. We were able to develop reduction techniques which were received positively from other colleges and collaborators.

I have collaborated with several researchers both from SISSA and from other institutes or universities during the PhD time. These collaborations were important in achieving novel scientific results. I have participated in several conferences or summer schools. I was also a member of the organizing group in one conference which was held in SISSA and also in another summer school which took place in SISSA.
