Dr Tabbaa specialises in understanding the modern human condition, particularly as it pertains to matters of Speech, Truth and Violence. His early research focused on the limitations of Human Rights as an emancipatory tool, with his thesis earning him peer recognition as a Legal Scholar. He also worked closely with affected communities during the decades of the War on Terror, including serving as an Executive Director at the Islamic Council of Victoria (ICV).

His later research focused on understandings and embodiments of Truthful Speech, from the Ancient notion of parrhesia to modern notions of Freedom of Speech, in pursuit of the question, How Can a Muslim Speak Truthfully Today? His research took a turn to trauma and mysticism when he uncovered his Complex PTSD after more than two decades of medical interventions. He subsequently used his research to develop a Trauma Healing modality and has since founded Elemental, a Trauma Healing Clinic in Marrickville, Sydney.
