EMPLOYMENT HISTORY
I – Staff Opto-Mechanical Engineer at Lumentum Operations, San Jose, CA (Sept. 2020- Current)
· Developing opto-mechanical designs of VCSEL measurement systems.
II- Mechanical Design Engineer at Lawrence Berkeley National Laboratory (LBNL)- Berkeley, CA (June 2020- August 2020)
· Designing mechanical assemblies of the new generation synchrotron at LBNL.
III - Opto-mechanical Design Engineer at KLA- Milpitas, CA (July 2019- May 2020)
· Designing opto-mechanical assemblies to mount optical elements such as mirrors and lenses. These assemblies will be used in the KLA’s new mask inspection tool (UHV system).
· Developing vibration isolation system of the tool to achieve nano-scale positioning tolerances.
· Developing alignment tools for aligning the optical system after tool assembly.
· Developing 6DoF adjustment capabilities in key assemblies.
IV- Senior Opto-mechanical Design Engineer at Veeco- San Jose, CA (April 2018- June 2019)
· Designing the mechanical mount for high power mercury lamp (2KW), The design provides means to adjust the lamp spark with respect to the ellipsoid focal point (tip-tilt and XYZ),
· The design included an extensive use of Solidworks® to create the CAD models, assemblies, and 2D drawings. Also Computational Fluid Dynamics (CFD) was used extensively to determine the required cooling air flowrate and directions to maintain the lamp and ellipsoid temperatures within specification limits,
· Bolt-calculations were conducted using an accurate calculation module,
· Design documents were maintained and shared using SAP system,
· Invented a new cooling method (patent is under processing) that provides high efficiency cooling for high power mercury lamps (2KW),
· Developed a metrology system and tools for aligning optical components and precisely put them in the right relative position. This method to be patent later.

· Worked for an academic year with Prof. Jay Raja, during which I made a preliminary data base that can be used to facilitate surface texture assessment of engineering surfaces.
IX-Summer internship in Ford Motor Company – Livonia- Michigan (May – August 2008)
· Worked on three different metrological projects related to surface roughness and flatness measurement of motor parts. Also, I was validating a software used for roughness measurement.
X-Teaching Assistant, Faculty of Engineering, Alexandria University, Alexandria, Egypt (Sept. 2000 – Aug. 2007)
I have taught the following courses:
· Participated in supervising graduation projects concerning dimensional and geometrical metrology, quality improvement, and total quality management. My role was to help students in carrying out the experiments of the practical part of their projects.
· Taught courses to engineers and technicians in the industrial field under the supervision of American University in Cairo (AUC) and Arab Academy for Science and Technology and Maritime Transport (AAST) These courses include "Fits and Tolerances" for technicians in Alexandria Iron and Steel Company, "Statistics" for engineers in Alexandria Iron and Steel Company, “Quality Engineering" for engineers in Petroleum Maritime Service Co.(PMS),"ISO 9000-2000 Series" for managers in the Egyptian Imports and Exports Monitoring Organization.
EDUCATION
PhD, Mechanical Engineering
University of North Carolina at Charlotte (UNCC), Charlotte, NC, USA (May 2013)
M.Sc., Mechanical Engineering
Alexandria University, Alexandria, Egypt (Feb. 2007)
B.Sc., Mechanical Engineering
Alexandria University, Alexandria, Egypt (June 2000)
PhD dissertation topic: Plasmonic Nanolithography Machine.
My PhD research project was about building a state of the art Plasmonic Nano-Lithography Machine (PLM). Working under the supervision of Prof. Robert J. Hocken, and working as a team member, I was responsible for the precision design and analysis of the machine parts. Also, I was involved in the machining, assembly and system integration phases.
The project was funded by NSF and was a result of the cooperation between the Center for Precision Metrology (CPM) at UNC Charlotte and the Center for Scalable and Integrated NanoManufacturing(SINAM).
M.Sc. thesis topic: Surface Texture Identification Using Optical Methods.
I have developed a binary Morphological Image Processing (MIP) approach to assess the roughness of engineering surfaces. This approach was analyzed mathematically and examined experimentally on real (shaped) specimens and ideal roughness forms (sinusoidal, circular, inverted circular, and triangular) and the results were found to be valuable. I had determined mathematical models to predict some of the surface roughness assessment parameters based on certain morphological statistics of the image and the incidence angle of light. Also, I used the results obtained experimentally to reconstruct a part of the roughness profile of the inspected surfaces. Also, my M.Sc. preparatory studies included Artificial Neural Networks (ANN) but did not contribute to the final thesis.
