IN MEMORIAM MATEV@ GOREN[EK (1972–2020) Dr. Matev` Goren{ek, specialist in orthopaedic sur- gery with a sub-speciality in diseases of the spine and feet, dedicated his career to the surgical treatment of de- generative diseases of the spine. Matev` Goren{ek was born on 16 th of May 1972 in Ljubljana. He successfully completed his veterinary studies at the Faculty of Veterinary Medicine of the Uni- versity of Ljubljana in 1999 and studies of medicine at the Faculty of Medicine in Ljubljana in 2004. He ob- tained his specialisation in orthopaedic surgery with hon- ours in 2010 and worked as a spinal surgeon at the De- partment for Orthopaedics Surgery in the University Medical Centre, Ljubljana. In parallel with his professional activities, he carried out scientific research based on the detection and treat- ment of degenerative diseases of the spine. For his work on the cultivation of stem cells for the implementation in intervertebral discs he received a PhD in Experimental Methods for the Prevention of Intervertebral disc Degen- eration In 2008. In 2016 Dr. Matev` Goren{ek MD, with his father Miro Goren{ek MD, and partners founded a new clinic, Sanatorium MD Medicina, to create a working environ- ment where the relationship between the patient and the doctor comes first and the doctor is directly accountable to his patients. In his position as Executive Director of MD Medicina his main focus was to establish a better system in which patients can take an informed decision and make choices between different institutions and dif- ferent doctors. Dr. Matev` Goren{ek dedicated his life to better health care so that it would be accessible to all pa- tients and at the highest possible level. Together with his daily work, he was extremely inter- ested in and aware of the importance of academic medi- cine, such as participation in congresses, presentation of research achievements, personal contacts with interna- tionally renowned experts, and the transfer of knowledge to Slovenia. He was very keen to foster the importance of transferring knowledge to young doctors and residents both at home and abroad. Dr. Matev` Goren{ek was one of the founders of the MD-RI Institute for Materials Research in Medicine, a public institute which was established in 2018 and ac- quired its first research projects in 2019 and 2020, thus enabling further research work. In particular, it was im- portant for him to meet a matrix of young doctors, clini- cians, older colleagues and to have their work presented at the International Symposium on Biomaterials and to publish their results in the scientific journal MIT, with its IF. Dr Matev` Goren{ek’s joy in research work remained undiminished, despite all his other professional obliga- tions in managing MD Medicina and his daily work as a spine surgeon. Future plans included new breakthrough stem-cell research, which following eventual clinical and regulatory approval was designed to be both patient- and clinician-friendly. Matev` was extemely active in the organization of all three International Symposia on Biomaterials. The Sci- entific and Organizing Committees decided that 4ISB will be dedicated to Matev`. We have lost an excellent orthopaedic surgeon, a re- searcher, a teacher and a good friend. We all miss him.
