Gorazd Kandus †2026
In memoriam prof. dr. Gorazd Kandus
Z žalostjo smo se poslovili od prof. dr. Gorazda Kandusa, zaslužnega znanstvenika Instituta "Jožef Stefan", dolgoletnega vodje Odseka za komunikacijske sisteme, uglednega raziskovalca, mentorja in cenjenega sodelavca.
Prof. dr. Gorazd Kandus se je Institutu "Jožef Stefan" pridružil leta 1979 in na njem deloval vse do upokojitve konec leta 2016. Med letoma 1993 in 2010 je vodil Odsek za komunikacijske sisteme ter pomembno zaznamoval njegov raziskovalni razvoj in mednarodno uveljavitev. S svojim delom od zahtevnih razvojnih projektov za slovensko industrijo do mednarodno odmevnih raziskav na področju satelitskih, brezžičnih in mobilnih komunikacij je prispeval k razvoju sodobnih telekomunikacijskih tehnologij. Pod njegovim vodstvom se je odsek uveljavil na številnih novih raziskovalnih področjih, med drugim kot eden od pionirjev raziskav komunikacijskih sistemov preko stratosferskih ploščadi.
Kot priznan strokovnjak je z delovanjem v različnih nacionalnih delovnih skupinah in strokovnih svetih pomembno prispeval k razvoju sodobne telekomunikacijske infrastrukture in storitev v Sloveniji. Kot dolgoletni vodja odseka, večkratni član Znanstvenega sveta IJS ter član Komisije za intelektualno lastnino in Komisije za podelitev priznanj pa je pustil trajen pečat tudi pri delovanju in razvoju Instituta.
Prof. dr. Gorazd Kandus ni bil le cenjen strokovnjak, izjemen raziskovalec in uspešen vodja, temveč tudi predan mentor številnim mladim raziskovalcem in doktorandom, ki jih je usmerjal in spodbujal na poti k samostojni raziskovalni karieri. S prenosom znanja in izkušenj na mlajše generacije je pomembno prispeval k nadaljnjemu razvoju področja in kontinuiteti raziskovalnega dela na odseku.
Za svoje izjemne znanstvene dosežke, vzpostavitev novih raziskovalnih področij, predano mentorsko delo ter velik prispevek k mednarodni prepoznavnosti Instituta na področju telekomunikacij mu je bil leta 2017 podeljen naziv zaslužni znanstvenik Instituta "Jožef Stefan".
Gorazda bomo ohranili v hvaležnem spominu kot izjemnega znanstvenika, predanega vodjo in predvsem kot toplega človeka.
