Associate Professor of Structural Biology, Director

Juha Huiskonen completed his Ph.D. project on cryo-EM of membrane containing bacteriophages in the group of Sarah Butcher at the Institute of Biotechnology in 2006. The next three years he was a visiting post doctoral fellow at the Max Planck Insititute of Biochemistry in Munich, in the group of Kay Grünewald, at the Department of Molecular Structural Biology, headed by Wolfgang Baumeister. In 2010, Juha started a research group focussing on virus-host cell interactions at the University of Oxford, Division of Structural Biology, headed by Dave Stuart and Yvonne Jones. This research project was initially funded by the Academy of Finland, Medical Research Council (UK), and later by an ERC Consolidator Grant.  Juha was recruited to HiLIFE as a Tenure Track Associate Professor in 2017 where his group continues to study structures and interactions of macromolecular complexes. In September 2020, Juha started as the Director of the Institute of Biotechnology.

Senior Researcher, Principal Investigator

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. She was awarded the title of Docent in Molecular Microbiology (2011) and served as a University Lecturer in General Microbiology (2012–2018). Currently she also acts as an editor in the Journal of General Virology handling the manuscripts in the field of prokaryotic virology.

Postdoctoral Researcher

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. Her current research takes place both at the University of Oxford and University of Helsinki.

Postdoctoral Researcher

Xiyong Song obtained his PhD at the Institute of Biophysics (IBP), Chinese Academy of Sciences (CAS) in 2018 and did his postdoctoral research at the Case Western Reserve University School of Medicine from 2019 to 2020. His past researches focused on the structural biology of the viral proteins, especially the nucleoproteins of the single-stranded RNA viruses/HBV and the glycoproteins of the coronaviruses with a approach including biochemistry and cryo-EM. Xiyong joined the lab in 2021 as a postdoc and his project is to elucidate the molecular mechanisms of vesicular transport combined with single particle and tomography (cryo-ET) methods.

Laboratory manager

Xun Lu completed her PhD in Biochemistry in North Carolina State University in 2013. She joined as a postdoc Oak Ridge National Laboratory.  There, her study focuxed on structures of protein/DNA complexes that are involved in DNA replication/transcription/repair.  The main techniques she used were X-ray/neutron crystallography and small angle scattering.  In 2017, Xun moved to Finland with her husband.  She joined the lab in 2021 as the lab manager.  Xun is thrilled to be back doing science, and eager to learn from her colleagues.

Doctoral Student

Ashwini Kedari completed her bachelor’s degree from India and later moved to Finland where she obtained her MSc. in Protein Science and Biotechnology from the University of Oulu. She was awarded Swiss-European Mobility Traineeship to carry out her master’s research project at the University of Zurich. Ashwini joined the Laboratory of Structural Biology as a doctoral student in 2020. She is working under the supervision of Ilona Rissanen, where her project focuses on the structural basis of virus-host interactions. In her doctoral research, she will combine cryo-EM and X-ray crystallography techniques to unravel the molecular mechanisms and architecture of viral proteins.

Doctoral Student

Evans Kofi Eshriew completed his undergraduate degree in Cellular and Molecular Biology with a minor in Chemistry from Mount Royal University, Calgary, Canada.
