Begun his working experience as fish biologist at the Dep. of Biological Applications and Technologies, University of Ioannina, as contractor (2009). Participated in the training program of graduates at the National Hatchery Station of Louros (2010-2011), under the auspices of the Hellenic Ministry of Agriculture.
Continued to collaborate as constructor with the Dep. of Biological Applications and Technologies until 2017, participating in 16 national and international projects in total. In 2012 attended the DEST Taxonomy training program in University of Ljubljana, Biotechnical Faculty (Ljubljana, Slovenia), Laboratory of Speleology while in 2014 enrolled in a seminar Ecological-environmental sustainable management and administration of infrastructure, buildings etc.
His research interests are on Ecological Quality Assessments of Lotic Ecosystems, Conservation and Protection of Freshwater Ichthyofauna and Management, Taxonomical classification of Amphipods, Decapoda larval developement.
He has contributed in 8 papers in peer- reviewed journals, as well as participated in 8 national and international conferences (2010 – 2017).
