In the context of his thesis, which he concluded with “summa cum laude”, Julian Prell developed an automated computer-system, which was capable of identifying A-trains, a pathological pattern of intraoperative facial nerve EMG in cerebellopontine angle surgery. The system was well suited to carry on further scientific analysis regarding intraoperative facial nerve EMG, and served as a basis for Julian Prell ́s future scientific work, which he continued as a resident in the Neurosurgical department of the University of Erlangen from 2004 to 2006.
In 2006, he relocated to Halle, Germany, together with his mentor Christian Strauss. Immediately after finishing his neurosurgical training in 2010, Julian Prell became an Attendant Neurosurgeon in Halle. The automated monitoring system for the facial nerve was developed further, and consecutive papers on this topic were published by his group. This work has been continuously supported by the Deutsche Forschungsgemeinschaft DFG since 2010.
Besides that, Julian Prell investigated into depth of anaesthesia in a cooperation with the Anaesthesiological Department as well as into the detection and prevention of perioperative thromboembolism together with the Department of Angiology, with high-ranking publications respectively. These projects have also been founded by the Deutsche Forschungsgemeinschaft and by local trusts.
In 2014, Julian Prell received the German postdoctorate lecture qualification and published his postdoctorate thesis, reflecting 15 years of basic and clinical research into monitoring of the facial nerve EMG and 10 peer-reviewed publications referring to this topic.
On the German national level, Julian Prell belongs to the permanent faculty which organizes annual training courses regarding Intraoperative Neurophysiologic Monitoring under patronage of the German Neurosurgical National Society DGNC. He is a member of the DGNC, ISIN and EANS, and he passed the Primary European Examination of Neurosurgery of the EANS in 2011.
