Brief Bio

Giannis Vatsellas is the lab scientific manager of the Greek Genome Center of BRFAA. He is a molecular biologist, graduate of the Department of Biology of the University of Crete and holds a PhD in Molecular Biology and Genetics from the Aristotle University of Thessaloniki. As an undergraduate he worked on the genetics of the malaria mosquito in the pest & disease control laboratory of Dr. Christos Louis at IMBB-FORTH. As a doctoral fellow he joined Dr. Dimitris Thanos lab initially at BSRC “Alexander Fleming” and subsequently at the BRFAA, where he studied mechanisms by which human genes respond to environmental stimuli during development and cellular differentiation. Upon accomplishing his Ph.D. thesis, he joined Dr. Yassemi Capetanaki lab at BRFAA, where his post-doctoral research focused on the genetic analysis of cardiovascular disease with NGS technology. In 2017 he re-joined Dr. Thanos lab, taking over the management of the Greek Genome Center of BRFAA. Apart from his post-doctoral research on the application of genomics technologies in understanding human disease, he has also designed, performed and analysed numerous genomics projects in collaboration with researchers and physicians in Greece and abroad, with a vast variety of different genomics technologies. He is an integral member of several Hellenic and European initiatives (Hellenic Precision Medicine Networks in Cancer, Cardiovascular disease, Neurodegenerative disease, Hellenic Network for Genomic Surveillance of SARS-CoV2 variants, CORBEL and others). Under his management the Greek Genome Center has performed the overwhelming majority of SARS-CoV2 virome sequencing in Greece, thus constantly improving our ability to better understand and address the SARS-CoV2 pandemic.
