Dr. Ghajar is a seasoned professional who brings in-depth experience in project management and coordination; marginal costing; computer applications; process redesign; and power system operation and planning. Some of his achievements are listed below.
- Dr. Ghajar was a key coordinator in an electric tariff study for Lebanon involving Electricité du Liban officials and external consultants. He also worked with the Kashida Electric Company in North Lebanon to perform a study on setting electricity tariffs for large industrial users, promoting sustainable growth and converting them to utility generation.
- He also coordinated the data collection and analysis for the USTDA-sponsored project on billing and revenue collection modernization for Electricité du Liban (EDL).
- In the U.S., he conducted comparative studies of two large computer programs for a law firm, to find the percentage ownership of various companies in order to allocate funds before the sale of these programs.
- In the Czech Republic, Dr. Ghajar conducted a thorough reliability evaluation of generating facilities for a U.S. consulting firm whose purpose was to secure grants from the World Bank to renovate these facilities.
- Dr. Ghajar took up software development, training, contract negotiations and project management in the areas of reliability evaluation and marginal outage costing for Power math Associates, San Diego, CA, and conducted research in the area of reliability modeling of protective systems.
- He completed a study for Distributed Energy Systems Group of San Ramon, CA to assess the status of use, techniques and data requirements for Reliability Centered Maintenance (RCM) in order to determine the applicability of RCM to the problems of electric transmission system operations and maintenance.
- In Canada, he conducted research in marginal outage costing and reliability evaluation of power systems, providing support and assistance to junior graduate students at the University of Saskatchewan, Saskatoon. He designed and developed PC-based software for reliability database and evaluation, and conducted research on renewable energy sources such as wind power.
- He developed and implemented a PC-based computer program for calculating the day-ahead marginal outage costs for Niagara Mohawk Power Corporation.
- He performed generation planning, reliability evaluation, production costing, generation expansion and economic evaluation for Alberta Power Limited, working closely with the CEO. Participated in hearings as a technical expert.
- He conducted real-time scheduling of generation and transmission at the Alberta Interconnected System Power Pool; coordinated emergency response plan; and developed a 240-hour scheduling tool and database.
- He engaged in the maintenance, enhancement and development of new energy planning software models for fossil and nuclear power plants at Ontario Hydro, Toronto, Canada. where he designed and developed an hourly load forecasting model and a load-weather forecast model.
Throughout his tenure at LAU, Dr. Ghajar has assumed responsibilities in strategic planning and project management and coordination. As chair of the LAU Strategic Planning Steering Committee, he coordinated the activities of nine sub-committees and liaised regularly between the external consultant and the president of LAU. Dr. Ghajar previously collaborated with the Center for Sponsored Research and Development at LAU on planning, designing, implementing and managing the Research & Development Conferences and Workshops program.
