 Research interests

My research interests are divided into two main tracks, the first with an international focus on automotive powertrain technologies, and the second at the local level with a focus on transportation and mobility challenges.

Road transportation worldwide is undergoing a rapid transition to more sustainable mobility solutions as an effective means of dealing with climate change and air pollution challenges. Thus, CO2 and pollutants emissions are key challenges for car manufacturers. Emissions and fuel economy standards are becoming increasingly stringent, and manufacturers must continually seek technological solutions to reduce consumption and emissions. Therefore, the development of new generations of powertrains goes along with the new regulations on consumption and emissions, and the state-of-the-art technological solutions are the electrification of the powertrains and the adoption of new alternative fuel converters, combined to waste heat recovery.

At the national level, the road transport system in Lebanon is one of the most unsustainable in the Middle East region due to, in large part, a chronic lack of enforcement of traffic laws and an underdeveloped and poorly maintained road infrastructure, leading to unregulated and chaotic driving patterns. Therefore, facing the diversity of proposed unconventional vehicle technologies by the transport industry, there is an imminent need to explore the impact of these technologies in Lebanon and developing countries with similar context, in order to inform stakeholders and local authorities on the transient strategies for the adoption of adequate mitigation options.

Thus, my research activities consist of the following:

  1. Improving energy efficiency and reducing emissions from vehicle technologies in order to make the automotive industry be compliant with the increasing stringent regulation standards
  2. Improving energy efficiency of passenger mobility in the Lebanese transport sector in order to help Lebanon meets its commitments to the United Nations Framework Convention on Climate Change and other related commitments

The first fold of research activities is done in collaboration with PSA Peugeot Citroen and Mines ParisTech, focusing in particular on optimizing the energy management strategies and powertrain topologies of electrified vehicles; and second, assessing the potential of new fuel converters operating on alternative fuels as substitutes to the internal combustion engines currently used on vehicles.

The second fold involves research collaboration with local governmental and non-governmental entities, namely, the Lebanese ministries of energy and environment, the United Nations Development Program (the energy and environment program) and the Lebanese Petroleum Administration. Typical conducted research activities evolve around environmental, energy use and costs assessments of transport technologies under local real driving conditions, assessment of mitigation measures based on Lebanon’s commitments for reducing fossil fuel use and CO2 emissions from road transport by increasing the share of fuel-efficient and electrified vehicles, and increasing the utilization of the existing bus service.
