I started and completed my studies at the Medical School of the University of Crete in 2002. As a student, I visited the ENT Clinic of Harvard University after exams and was impressed by the breadth of the ENT specialty. I started and completed my specialty from 2005 to 2010 at the University Clinic of Erlangen, which is one of the three largest ENT Clinics in Germany with 90 beds and 6 operating rooms daily. It is one of the largest and perhaps the most famous salivary gland center worldwide, (modern sialendoscopic tools were developed in Erlangen), the largest cochlear implant center in Bavaria and one of the largest surgical centers for Head and Neck Oncology in Germany.

After my training in general surgeries of the specialty (tonsillectomy, septoplasty, etc.) I was particularly trained in head and neck surgical oncology and salivary gland surgery, resulting in me performing unsupervised cervical lymph node dissections from the 3rd year and laryngectomies from the 5th year of the specialty. A year before the end of the specialty, I even started working on call as a supervisor! In addition, I was trained in endoscopic surgery of the paranasal sinuses. During the specialty, I also received 6 months of training in the treatment of seriously ill patients in the intensive care unit of the ENT clinic.

In July 2010, I successfully passed the exams and received the title of ENT specialist and continued to work as a second-year supervisor and since December 2013 as a first-year supervisor at the Erlangen clinic. I was trained and specialized in surgical oncology and in particular in transoral microsurgery of Laryngeal and Vocal Cord tumors with CO2 Laser and plastic surgery of flap reconstruction. In addition, in surgery of the Head and Neck Glands with particular emphasis on parotidectomy and thyroidectomy, in microsurgical anastomoses of the facial nerve. Also in endoscopic paranasal sinus procedures, such as ethmoid surgery  and cerebrospinal fluid rhinorrhea restoration. 

In thyroid surgery I trained with a special scholarship at the University Clinic in Prague and then organized and in 2012 became  Head of the Thyroid and Parathyroid Surgery Department in Erlangen, performing more than 150 operations until my departure from the clinic in 2014. In addition, after practical training and participation in special seminars, I began to independently perform ear surgeries.

The Erlangen clinic has one of the largest and most specialized ultrasound centers in Germany, conducting three certified Head and Neck Ultrasound seminars every year DEGUM (German Society for the Use of Ultrasound in Medicine). In 2010, I was responsible for the department for 6 months (under the guidance of the deputy director, Prof. Zenk), performing more than 2000 ultrasound examinations. I then received the title of instructor (DEGUM level 3) and since then I have maintained a particularly active role in the training of colleagues and a scientific interest in head and neck ultrasound.In total, I have performed more than 10,000 ultrasound examinations and am now a DEGUM 3 instructor (higher level). In April 2019, my post-graduate training in head and neck ultrasound was recognized by the Ministry of Health in Greece and I became the first hospital ENT Doctor in Greece with the right to perform and teach Head and Neck Ultrasound to Otolaryngologists in our country.

In March 2014, I accepted the invitation of Professor J. Zenk and was appointed Deputy Director and Deputy Director of the AugsburgUniversity Hospital , which has more than 60 general and 4 intensive care beds. It also has 3 operating rooms per day, in which a total of more than 3,000 operations are performed each year.

At the Augsburg Clinic I was responsible for the surgical treatment of patients with diseases of the Head and Neck Glands (Parotid and Thyroid) and head and neck tumors, especially those requiring transoral resection with CO2 Laser and plastic reconstruction with pedicle and free flaps. I also frequently chaired the clinic's weekly oncology board. In total, I have performed more than 1000 oncological operations and more than 100 flaps.

In addition, I was responsible for the Ear Surgery department , where I performed approximately 100 ear surgeries per year (more than 400 surgeries in total). I was also responsible, together with Professor Zenk, for salivary gland, thyroid and cochlear implant surgeries. In particular, we developed the cochlear implant department completely, since from one surgery in 2013, in 2018 we performed more than 40 surgeries (20 of which I performed as the sole surgeon). On average, I performed more than 400 surgeries per year from 2010 to 2019. In 2019, after exams, I received the specialization title “Plastic Surgery of the Head and Neck” in Germany.

In May 2018, , I was elected full professor of Otolaryngology at the University Clinic of Ioannina where I was sworn in and assumed duties in April 2019 under the direction of Professor Mr. Ioannis Kastanioudakis. 

In September 2022, I took over the management of the ENT clinic of University Hospital of Ioannina, in a clinic that now has 7 residents and and 6 specialized doctors and covers the widest range of Head and Neck surgery. Under my direction, the ENT Clinic has become an important Surgical Center for the whole of Epirus, especially in the Surgical Treatment of Laryngeal Tumors Laser CO2 for the Surgery of the Salivary Glands (Parotid, Submandibular) and for the Surgery of the Thyroid and Parathyroid Glands. In addition, it has become the first Head and Neck Ultrasound Training Center in our country. 

In addition, since 2021 I have started collaborating with the largest private hospitals in Greece, such as IASO Thessaly and Athens, the Inter-Balkan Medical Center of Thessaloniki and the Euromedica General Clinic of Thessaloniki to perform specialized surgical procedures.

Upon my appointment at Erlangen in 2005, I began Διδακτορική μου Διατριβή entitled "The Evaluation of the New TNM Classification (2002) for Advanced Laryngeal Neoplasms" under the supervision of Prof. Iro. Which I completed in 2009 with "high distinction".

Since 2008, I have been the scientific director of the official Erlangen oncology database with more than 9000 patients and we have started the immunohistochemical and PCR analysis of patients with oropharyngeal cancer for the detection of the HPV virus, which has also been my main research field and within the framework of the thesis on Hyphegiasis which I completed in 2013 and for which I was awarded a prize of €2,500 by the Dr. Wolfbauer-Stiftung.

After completing my postdoctoral studies, I was appointed as an assistant professor (Privatdozent) first in Erlagen and then at the University of Munich LMU, a position I still hold today. Additional research areas were the salivary glands, sialendoscopies and the use of elastographic ultrasound. Also since 2009 I have been a certified controller of clinical research programs and participated in several prospective multicenter studies. In Erlangen I supervised three doctoral theses, one of which (Ryzek) from beginning to end. In total I have 65 publications, of which 61 in Pubmed with a cumulative impact Factor of 105 and approximately 750 bibliographic references (h- Index=17, i-10 Index=25)

In Ioannina, I am a supervisor of doctoral theses on HPV in head and neck oncology, in thyroid and parotid surgery. We participate as a clinic in a multicenter study on the importance of HPV in oropharyngeal cancer and we are the 2nd center nationwide in number of patients. In addition, we continue research protocols and the importance of Elastography in head and neck ultrasound as well as the importance of Neuromonitoring in parotid and thyroid surgery. In October 2022, I organized the 1^st Seminar  on Diagnostic and Interventional Ultrasound in Ioannina, which you repeat with great success every year.

As part of my dissertation on the Epidemiology, I attended a series of seminars (80 hours) on University Teaching and obtained a title of University Teaching Efficacy. I also participated in the PERLE program and was the sole responsible for the course "In-depth ENT examination", in which students were taught the use of rigid and flexible endoscopes , ear microscopy and the use of ultrasound in the cervix.
