In 2010, he joined the University of Strasbourg to obtain a Master's degree on Science of Medicaments, major Pharmacology, and also a University Diploma in clinical research. During his masters, He worked on the innate immune system and especially on Neutrophil Extracellular Traps (NETs) at the Institut de Génétique et de Biologie Moléculaire et Cellulaire in Strasbourg, France.
Antoun started his PhD in 2014 at the Laboratory of Experimental Cancer Research, Department of Oncology at the Luxembourg Institute of Health. The objectives of Antoun's thesis is to study the role of breast tumor actin cytoskeleton in the resistance to natural killer (NK) cell-mediated cell lysis. With the use of the imaging flow cytometry, He studied the immune synapse between tumor cells and NK cells and applied various masks and features to characterize 1) actin cytoskeleton modification, 2) lytic granules transfer 3) ligand and receptor accumulation and 4) autophagosome clustering.
