She has been working as a research scientist at HCMR since 1998, and has acquired a broad experience as a fisheries biologist. She assumed her duties as a Researcher in HCMR in October 2006. Since November 2016, she is a Research Director at the Institute of Marine Biological Resources and Inland Waters at HCMR.
She has multidisciplinary research interests, focusing on the population dynamics of small pelagic fish, physical/biological interactions in marine ecosystems, fisheries acoustics, spatial analysis techniques, determination of essential fish habitat and habitat suitability modelling, food web modelling as well as stock assessment modelling techniques, marine mammals distribution, marine megafauna stranding events, bottom trawl discards, incidental catch, invasive species. She has attended special training courses in fisheries acoustics and acoustic data analysis, fish stock assessment using FLR, habitat modeling techniques, analyzing biological and environmental field data, sampling design for field data, geostatistical analysis for acoustic surveys, Introduction to Bayesian inference in fisheries science, Food web modeling with E2E.
She is an active member of the Steering Committee of the Mediteranean International Acoustic Survey (MEDIAS) as well as an active member of the stock assessment study groups in the Mediterranean region (i.e. GFCM, STECF, FAO-EastMed) being responsible for the application of stock assessment models for anchovy and sardine stocks in the Greek Seas, providing essential information for management advice and the production of fishery management plans. She has organized/coordinated an International Workshop on the use of geostatistical techniques on acoustic surveys design (ICES WGACUGEO), as well as various workshops within the framework of scientific projects on the application of habitat modeling techniques. Since 2019 she is the Chair of the GFCM Working Group on Stock Assessment of Small Pelagics (WGSASP). She has a high level of expertise on spatial analysis techniques, predominantly geostatistics and generalised additive models. She has done pioneer work within the Mediterranean region in respect to the application of habitat suitability models for small pelagic fish species. She has participated in more than 25 national and international projects while served as the scientific co-ordinator of 3 European Union (EU) projects.
She has contributed to 57 papers in peer-reviewed journals, 3 book chapters, as well as more than 100 publications in conference proceedings, special publications, newspaper and magazines. She has co-authored more than 20 technical project reports.
