Jaser Abu Mousa is a Yale Peace Fellow examining how Gaza's postwar reconstruction can reflect Palestinians' priorities while repairing the social fabric of society.

Most recently, he was a Program Officer working for the Swiss Agency for Development and Cooperation (SDC) in Gaza, Palestine until the breakout of the current war in October 2023. During the war, Jaser lost his wife, Heba, and two children, Hmaid (18) and Abdulrahman (8), and left Gaza with his remaining two children, Abdallah and Sham, for treatment in the United Arab Emirates.

Prior to his work with Swiss, Jaser served in the UN Department of Safety and Security (UNDSS), working under immense pressure during the 2014 war to report incidents, coordinated and communicate movements and follow intense political developments. Prior to that, Jaser worked as a social worker for the United Nations Relief and Works Agency (UNRWA) in the aftermath of the 2009 war, including leading a team of 50 social workers to run the poverty survey for UNRWA in the area of Khan Younis in the southern Gaza Strip. He also led a team of engineers to verify the work of a European contribution 30 million Euros known as the Private Sector Reconstruction in Gaza (PSRG). Between 2006-2009, he worked extensively as a political researcher in a Gaza-based think tank; during this period he reported on and analyzed Hamas’ rise to power in the Strip.

Jaser holds a Bachelor of Science in Civil Engineering from the Islamic University of Gaza and a Master of Science degree in Project Management. In addition to his work as an analyst and a development/humanitarian practitioner, he has worked as a civil engineer at private construction companies and UN agencies.
