He is an Elected fellow of the American Academy of Microbiology and in 1999 was awarded the Ivanovsky Medal for “Contributions to the Development of Virology” by The Scientific Council of Virology of Russian Academy of Medical Sciences.

Professor Wendy Barclay

Professor Wendy Barclay joined Imperial College in May 2007, moving with her research group from the University of Reading where she had previously been based since 1995.  She graduated in Natural Sciences from Cambridge University and had undertaken her PhD at the Common Cold Unit, Salisbury under joint supervision of Dr David Tyrrell and Dr Fred Brown, studying the human immune response to rhinovirus.  She acquired molecular virology skills as a postdoctoral fellow first in the laboratories of Professor Jeff Almond at Reading, and then working with Dr Peter Palese at the Mount Sinai School of Medicine, New York.

Professor Barclay’s expertise is in the field of respiratory viruses, in particular influenza virus. Her studies aim to understand the molecular and cellular basis of the pathogenesis, host range restrictions and transmissibility of influenza viruses. The approach includes the generation of recombinant viruses with defined mutations. This strategy has contributed to the production of novel influenza pandemic vaccines. Translational aspects include analysing mode of action and resistance mechanisms of antiviral compounds, and characterization of novel cell substrates and attenuated virus backbones for influenza vaccines.  Her laboratory is funded by grants awarded by the European Union, MRC, BBSRC, and Wellcome Trust.

Professor Persephone Borrow

Professor Persephone BorrowProfessor Persephone Borrow is a viral immunologist whose research interests centre on understanding virus-immune system interactions and their roles in determining the balance between virus clearance versus viral persistence and associated pathogenesis.

She obtained a BA(Hons) degree in Natural Sciences from the University of Cambridge, UK and stayed at Cambridge to study for a PhD under the supervision of Professor Tony Nash. After this she carried out postdoctoral research with Professor Michael Oldstone at The Scripps Research Institute, USA, where she subsequently progressed to become an Assistant Member. She then returned to the UK to lead the Viral Immunology Group at the newly-established Edward Jenner Institute for Vaccine Research, and in 2005 joined the Nuffield Department of Medicine at the University of Oxford, where she currently holds the position of Professor of Viral Immunology and is also a Jenner Institute Investigator.

Her research team, based at the NDM Research Building on Oxford University’s Old Road Campus, focuses mainly on analysis of CD4 and CD8 T cell responses and innate responses in HIV infection, aiming to inform the development of vaccines and other prophylactic and therapeutic strategies based on modulation of T cell and innate immunity; and is also performing some comparative studies of innate responses in other human virus infections including herpesvirus infections.  Her group’s research is largely funded by the MRC and the US NIH.

He has also been a founder shareholder and consultant to a number of biotech companies and a member of many UK and overseas funding panels, advisory boards and Councils. He was elected a Fellow of the Academy of Medical Sciences in 2011.

His main research interests have centred on bacterial diseases of humans and other animals, with zoonotic bacteria such as Salmonella, Campylobacter and Streptococcus suis being particularly constant elements of his research portfolio. His work has covered all aspects of the host-pathogen interaction, from how the bacteria themselves work, through to how host responses operate to lead to infection or clearance of the bacteria, and he has been a keen advocate for using genomics to study these pathogens in the laboratory and in the field.

Professor Thomas Mettenleiter

Professor Thomas Mettenleiter For more than 30 years Thomas Mettenleiter has performed research primarily on herpesviruses, in particular herpesviruses of animals. He has trained as a molecular biologist at Tübingen university from 1977-1982, then started his PhD work at the then Federal Research Centre for Virus Diseases of Animals (the current Friedrich-Loeffler-Institut).    

After obtaining a PhD with studies on pseudorabies virus (PrV) glycoproteins he went to performed research at Vanderbilt University, Nashville, USA for 18 months to continue his work on PrV in collaboration with Professor Tamar Ben-Porat, then the world's leading PrV researcher.  After his return he was appointed director of the department of molecular and cellular virology at Insel Riems.  His scientific studies on the molecular biology and pathogenesis of animal herpesviruses provided important results to understand the structure, replication, virulence and tropism of herpesviruses and for the development of novel vaccines.  His results contributed to the first development of marked vaccines and, thus, for the efficient control and eradication of Aujeszky's disease in pigs.

Since 1997 he is president of the Friedrich-Loeffler-Institut (FLI), Federal Research Institute for Animal Health, with headquarters on the Isle of Riems close to Greifswald, the world's oldest virological research institute.
