About me

I received my B.Sc. degree in Molecular Biology and Genetics from Dimokritus University of Thrace (Greece - 2005). I subsequently received a Ph.D. in Medical Sciences from B.S.R.C Alexander Fleming (Greece - 2009) with special focus on post-transcriptional modifications and their role in hematopoietic development and colon cancer. In 2010 I had 1 year interruption in research due to my compulsory military service where I specialized as Microbiologist Assistant in the microbiology laboratory of Military Hospital for Special Diseases (414; Athens, Greece). I then joined the group of Professor Eva Hellström-Lindberg and Professor Sten-Eirik Jacobsen at Karoliska Institute (Sweden – 2011) as post-doctorate researcher to focus my research on the hematopoietic and MDS (myelodysplastic syndromes) cancer stem cells. From October 2017, I am an Assistant Professor and research associate for Professor Eva Hellström-Lindberg at Center for Regenerative Medicine and Hematology (HERM), Department of Medicine Huddinge, Karolinska Institutet. Overall, I am specialized in molecular biology, RNA  and post-transcriptional field, in HSC and leukemic/cancer stem cell biology, various molecular biology/genetics and sequencing platforms as well as multi-color flow cytometry sorting.


2005, B.Sc. in Molecular Biology and Genetics, Democritus University of Thrace, Alexandroupoli, Greece 

2009, Ph.D. in Medicine at University of Ioannina and Biomedical Sciences Research Center Alexander Fleming, Greece

2011-2017, Postdoctoral researcher, HERM, Department of Medicine Huddinge, Karolinska Institutet, Sweden

Research description

My research focus is on malignant hematopoietic stem cell (HSC) functions and MDS stem cells. The overreaching aim is to characterize the cellular and molecular heterogeneity but also the RNA usage within MDS stem cells. The vision is to explore novel solutions and tools to treat the disease in its origin by understanding and manipulating the RNA dynamics of MDS stem cells.
