- Conducted full functional experiment design and statistical analysis on the preparation and finishing processes of cellulosic fibres. - Implemented measures to simultaneously achieve improved product quality and reduced emissions to process water. - Applied work to 5 SME's as part of a public-private partnership called "National Campaign for Textile Development in Egypt". Best case results showed cost reductions of 100K£. - Disseminated work in an industrially oriented handbook for Cleaner Production in Textile Industry. - Gave multiple presentations and lectures for the NRC's staff on environmental and risk assessment best practices, Cleaner Production concept, Environmental Management System, Self-monitoring and Risk Assessment in the Textile Industry. - Worked on organising and editing several international symposia, workshops and conferences, in addition to serving on technical editorial board and international experts selection committees at the conference unit of the NRC.

- Conducted the Environmental Impact Assessment (EIA) for a vehicle-scrapping project in Cairo funded by the World Bank in collaboration with the Egyptian Ministry of Finance. - Updated the EIA for a wind farm project in the Red Sea.- Wrote a number of technical and financial proposals for projects such as: plastic recycling, E-waste management in Egypt and Disaster Risk Management in the Arab Region.- Conducted a number of Environmental Audits for various plants in Greater Cairo and Egypt.

MPhil (Master of Philosophy) in Engineering for Sustainable Development.Thesis entitled: ‘Toward Energy Efficient Buildings in Cambridge: A case study at Pembroke college’.- The MPhil was both a coursework program where I studied courses such as: Sustainability in Chemical Engineering, Electricity and Environment, Multi Criteria Decision Making, Project Management as well as a number of modules regarding the business development. - Conducted a case study of the energy efficiency in Pembroke College in Cambridge to assess the feasibility of low carbon footprint technologies in existing buildings using localized technologies rather than centralized methods.

Developed silica removal process so that waste rice straw (which is usually burned) could be reused as part of a paper pulping process. Showed reduction of CO2 emissions.
