Mohammad Ghanem graduated with a dual bachelor degree- B.Sc. in Pharmacy in 2015 and LLB in Law in 2017 from Tishreen University (Syria). After graduation he was invited to teach in the practicum of Clinical Biochemistry at the faculty of Pharmacy at Tishreen University, where he further developed his passion for biochemistry. In 2019, Mohammad started his master's studies in pharmaceutical biotechnology at the University of Milan and joined the laboratory for his thesis project. Mohammad's project focused on the optimisation of nanoparticles for the use as small protein-displaying systems in the cryo-EM imaging studies. After his graduation, Mohammad returned to the group to pursue a PhD in the field of structural and cell biology of protein aggregation in neurodegenerative diseases.
Ilona Rissanen earned her PhD in 2014 from the University of Jyväskylä, Finland. Her PhD project in the group of Jaana Bamford was focused on the crystallographic investigation of an extremophile bacteriophage, and incited her lasting interest in the study of viral structures. From 2014 to 2017, Ilona was a postdoctoral researcher at the University of Oxford working with Thomas Bowden, whose group investigates the structure and function of viral glycoproteins that are the key determinants of pathogenicity for emerging viruses. In 2017, Ilona was awarded Postdoctoral Researcher funding by the Academy of Finland to study the molecular mechanism that govern virus–host interactions of pathogenic hantaviruses. In September 2021, Ilona started as an Academy Research Fellow and Principal Investigator at the Institute of Biotechnology.
Elina Roine started as a Senior Researcher in the Laboratory of Structural Biology in the beginning of 2019. For her PhD she studied the role of extracellular filamentous protein structures, for example pili, in the pathogenesis of Pseudomonas syringae. Her post-doctoral research as a Marie Curie Individual Fellow at the University of Leiden focused on type IV protein secretion in Agrobacterium tumefaciens. She moved to the laboratory of Professor Dennis Bamford (University of Helsinki) to study molecular interactions of prokaryotic viruses with their hosts.
