I am a skilled researcher with a major interest in the fabrication and testing of thermo-mechanical fatigue and creep in soldered/welded joints. I have several years of experience in the design of experiments to analyse soldered/welded joints, and the design of test equipment. I have a keen analytical mind, with experience in statistical analysis and presentation of experimental data, coupled with strong skills in FEA and mathematical modelling. FEA models were created using Abaqus Implicit/explicit and Ansys. Moreover, it included writing Python scripting to add unsupported constitutive material behaviour, atomization and optimization to models. Models are built using a complex meshing, parting, partitioning and boundary conditions techniques that require a deep understanding of multi-face interactions and convergence analysis. During my PhD I worked as a teaching assistant with particular focus on lab demonstrations and marking of student works. I also undertook some lectures on mechanical modelling to both undergraduate and master’s students. Education
Heriot-Watt University, Edinburgh, UK
PhD (Mechanical Engineering) 2007– 2014
For my PhD project I designed a novel micromechanical system to experimentally study the mechanical and thermal fatigue of lead-free solders for advanced microelectronic applications. This design required the development of a variety of skills including instrumentation and control (hardware, software and finite element analysis). I also developed advanced soldering techniques which were required for specimen preparation. The specimens were tested under displacement control while recording the number of cycles to failure as well as the cyclic stress-strain behaviour. The samples were examined microscopically before and after testing to determine if and how the micro structural and micro-hardness constituents changed. Tishreen University, Latakia, Syria
B.Sc (Hons) First Class degree in Mechanical Engineering and Production 1997– 2003 Consultancy Experience
University of Leeds, Faculty of Engineering, Departments of Mechanical CIRCOR Energy, Pipeline Engineering & Supply Co. Ltd 2014–current
The project supports an on-going collaborative KTP venture between the School of Mechanical Engineering and Pipeline that will enable the company to add value to its existing range of closure products and secure market penetration for large diameter mechanisms & very high pressure mechanisms (greater than 5000psi design pressure). The project included identification of load cases, build and validation of appropriate finite element models, lab-based material characterisation, design and optimization. I designed a prototype taking into account specific criteria: Structure and material considerations, Design by rule, Design by analysis, Factor of safety, Modes of failure (elastic failure and plastic failure), Allowable stress limits in the ASME Pressure Vessel Code, Categorisation of stresses: Primary stress, secondary stress, peak stress, and stress limits, and Theories of failure used in ASME Pressure Vessel Code: Tresca criterion, Von Mises criterion, and stress intensity.

2009–2014
I was responsible for the supervision of several Masters students from the Edinburgh Dental hospital. The supervision comprised teaching the students some required mechanical background information (manufacturing system design, control system theory and practice, signal processing and data analysis) Heriot-Watt University, Department of Mechanical Engineering & Epcos Electronic Components, Spain
2009–2011
The project dealt with the design and failure analysis of enclosures for power capacitors. I was responsible for examining the field failure, designing test specimens, Finite Element Analysis (FEA) of the load-deflection characteristics, validation of FEA simulations, and examination of the microstructure of different types of welded joints.

Laboratory/Tutorial/Teaching Assistant. Helping undergraduate students to solve tutorial problems. Skills
Analytical and Problem-Solving
The solution of problems using complicated concepts and knowledge is a key part of my undergraduate degree course and my PhD studies. For example, I encountered a problem calculating the true strain in solder joints between heterogeneous materials which I solved by creating a new calibration technique and validation using Finite Element analysis.
Efficient prioritising of workloads to meet deadlines is a skill I have demonstrated throughout my academic life. Numeracy and Computing
Advanced mathematics and the analysis and interpretation of data are key parts of my degree course. An example of this would be when I calculated the kinematic equations for an Aries/Equator delta robot and used matrix manipulation to analyse the motion of the tool head.
Competent with all Microsoft Office applications.
Programming modules in my degree have enabled me to become proficient programming in Maple, MATLAB, Abaqus Finite Element Analysis (FEA) software and LabVIEW software.
Familiar with Solid Edge, SOLIDWORKS and inventor Autodesk 3D CAD software. Communication and Interpersonal Skills
Presentations and written reports were assessed at every stage of my degree course and have enabled me to develop my written and verbal communication skills to a high standard. Presentations and written papers are a major part of the PhD.
Completed the Learning Enhancement and Development Skills (LEADS) 1 and 2 course which further developed my teaching and communication skills by backing up my several years of experience with theoretical examples and assessed practical teaching scenarios.
Teamwork
During my time at Heriot-Watt University I participated in several interdisciplinary international group projects in which my teamwork skills have been greatly developed. An example of which was the Epcos Electronic Components project that involved joining a team composed of different types of engineers that worked together to design, build and investigate the cause of power capacitor case failure.
