Since 2006 she has been with CERTH, where she is a Principal Researcher and head of the HydPro group of CPERI. Her research focuses on environmentally friendly fuels and biofuels and on hydroprocessing optimization. She is scientific advisor in European and national projects, author of numerous publications and winner of the 2nd prize in the “Greece Innovates” competition (2011).

Dr. Athanasios Dimitriadis holds a Mechanical Engineering diploma (2008) and a PhD (2021) from the Aristotle University of Thessaloniki, with a thesis on the effects of hydrotreated vegetable oils on internal combustion engines and their emission control systems. He joined the HydPro group of CPERI/CERTH in 2010, where he is the head engineer of the hydroprocessing pilot plants.

His research covers advanced, electrified and environmentally friendly fuels and 2nd and 3rd generation biofuels technologies. He is co-author of more than 26 journal papers and 66 conference proceedings and, since 2022, also teaches at Institutes of Vocational Training in Thessaloniki.

Dr. Loukia Chrysikou holds a Chemistry diploma, a Master’s degree and a PhD from the Aristotle University of Thessaloniki, where she studied airborne particulate matter and automotive exhaust emissions. Since 2011 she has been a research assistant in the HydPro group of CPERI/CERTH.

Her research focuses on the aging of fuels and biofuels and on the Life Cycle Assessment of fuel and biofuel production processes. She has participated in European and national projects and is co-author of several scientific publications.

George Meletidis holds an Engineer of Petroleum & Natural Gas Technology diploma from the Technological Educational Institute of Kavala. Since 2011 he has been a member of the HydPro group of CPERI/CERTH, operating the pilot plant units in hydroprocessing experiments for biofuels production.

He is also the safety manager of the group and a member of the Emergency Response Team of CPERI/CERTH.

Ioanna Kosma holds a Chemistry diploma (2019) and a Master’s degree with excellence (2021) from the Aristotle University of Thessaloniki. Since 2023 she has been working as a research and development chemist in the HydPro group of CPERI/CERTH.

Her research focuses on biomass characterization and pretreatment prior to its upgrading to alternative transportation fuels. She has participated in national and European research projects.

Dimitrios Liakos graduated with excellence in Chemical Engineering from the Polytechnic School of the Aristotle University of Thessaloniki in 2020. He is a PhD candidate at the Department of Chemistry of AUTh, working on the hydrothermal liquefaction of various types of biomass for bio-oil and biofuels production.

Since November 2020 he has been a postgraduate fellow at CPERI/CERTH, involved in the development of the biomass hydrothermal liquefaction process.

Nikolaos Tourlakidis is a Mechanical Engineer, graduate of the International Hellenic University (former TEI of Central Macedonia – Serres), receiving his diploma in May 2022.

He carried out his internship at CERTH on the operation and maintenance of catalytic hydroprocessing pilot plants.
