Mahmoud Khalil is a Palestinian-Syrian activist and former graduate student at Columbia University, born in 1995 in a refugee camp in Damascus, Syria. He holds Palestinian refugee roots from Tiberias and grew up in Syria before pursuing higher education. Khalil earned a bachelor's degree in computer science from the Lebanese American University and completed a master's degree in International Affairs at Columbia University's School of International and Public Affairs in 2024[1][3]. Before his activism prominence, Khalil worked in international development and social services, including managing the Syria Chevening Program at the British Embassy in Beirut, which is a UK government international scholarship scheme. He has been described by colleagues as thoughtful, intelligent, and conscientious[1][4]. He also worked with Syrian refugees and non-profit organizations focused on education[4]. Khalil became widely known for his leadership in the pro-Palestinian student movement at Columbia University, particularly during the 2024 campus occupations advocating for Palestinian rights and against alleged university complicity in Israeli policies. He served as a lead negotiator between student protesters and university administrators, helping mediate tensions without directly participating in building occupations[1][2]. His activism drew national attention and controversy, especially within debates on academic freedom and immigration policies in the United States. In March 2025, Khalil was detained by U.S. Immigration and Customs Enforcement (ICE) in Louisiana, despite holding a U.S. green card that grants him permanent residency. His detention sparked widespread discussion about immigration enforcement and the rights of activists, with his case potentially reaching the U.S. Supreme Court[1]. On a personal note, Khalil married Noor Abdalla, an American dentist, in 2023, and they are expecting their first child in April 2025[1][4]. He has been featured in the 2025 documentary "The Encampments," which chronicles the pro-Palestinian student protests[1][3]. His net worth is estimated under $100,000, primarily from scholarships and part-time consulting[1].
