Key Qualifications: Assistant professor at Birzeit University teaching water treatment, wastewater technology, infrastructural planning and project management in both undergraduate and graduate programs. Practical experience in water and wastewater with a professional career spanning three decades. My duties include designing and co-ordination of research and development projects in the field of water and wastewater management. I’m specialized in urban and rural areas water supply and wastewater treatment technologies and has recently been involved in several projects aiming to introduce wastewater treatment plants and has provided technical services in the field of water supply and sanitation. Chairman of the technician training – wastewater working group (WG2) within the four Palestinian water and wastewater working groups founded by the Palestinian Water Authority to manage training in Palestine. Widespread experience in the planning of infrastructural projects.
Consultant and project manager for the feasibility study for the sewerage system to serve the Rawabi community. Developer of evaluation reports for operation units at the wastewater treatment plant in Al-Bireh, West Bank. Author of feasibility study for the treatment and disposal of the wastewater for the municipal area of Ramallah and technical reviewer for project documents. Team leader for several environmental studies conducted for wastewater treatment plants and several industries in Palestine. Given lectures and presentations at numerous national and international symposiums, courses, seminars, workshops and conferences.
