Professor Wendy Barclay - Chair in Influenza Virology, Imperial College London

Wendy Barclay

After graduating from Cambridge University, Wendy’s postgraduate study at the Common Cold Unit in Salisbury involved infecting human volunteers with cold viruses to understand why people keep getting colds year after year. In her two postdoctoral appointments, at the University of Reading and then Mount Sinai Medical Centre in New York, Wendy learned the molecular virology skills that would form the technological basis of her research career.  Upon returning to Reading in 1995 to a junior lectureship, she set up her research group to study influenza viruses.  In May 2007 she took up a Chair in Influenza Virology at Imperial College London. 

She is particularly interested in the mechanism by which viruses can cross from animal sources into humans to cause new pandemics. She sits on several advisory boards, for example, offering advice about respiratory virus outbreaks and also work with the Science Media Centre, whose aim is to improve the relationship between scientists and the media. Wendy has two children and a loving husband and they all enjoy skiing in the winter and sailing in the summer.


Dr Jason Long - Research Associate

Jason Long

Jason completed a joint PhD project between the Barclay lab and the Animal and Plant Health Agency, investigating the likelihood of highly pathogenic H5N1 bird flu viruses obtaining human adapting mutations. He has been a Post-Doctoral Researcher at the Barclay lab since 2014. His current work focuses on the host restriction of the influenza polymerase and the development of a novel imaging system to visualise influenza infection in chickens, in collaboration with the Roslin Institute and the University of Cambridge.


Dr Daniel Goldhill - Research Associate

Daniel Goldhill 

Daniel is a post-doc in the PRU in Respiratory Infections jointly between Public Health England and the Barclay lab at Imperial College. He has been researching how influenza virus might develop resistance to favipiravir, a new antiviral drug. Following his undergraduate degree in Biological Sciences at Oxford University, he crossed the Atlantic to do a PhD in Evolutionary Biology at Yale University. He joined Professor Paul Turner’s lab where he studied experimental evolution using the bacteriophage φ6. He was particularly interested in trying to understand adaptation by tracing a change in virus phenotype through a change in the genotype to a structural change in the protein to explain the phenotype.  Since 2015, he has switched to work on a eukaryotic virus and has been using experimental evolution in an attempt to understand the mechanism through which influenza might develop resistance to favipiravir.  Hopefully, his work will lead to a public health benefit in that we will be able to understand how viruses may become less susceptible to the drug and design better assays to test for resistance.


Dr Carol Sheppard

Dr. Carol

Carol received a BSc (Hons) Biochemistry degree from the University of Bath in 2007. During her degree, she worked for a year at GlaxoSmithKline developing techniques to measure preclinical biomarkers. After graduating she spent some time at UCB Celltech investigating the use of antibodies as therapies for autoimmune diseases.

In 2008, Carol started a PhD in Molecular Microbiology at Imperial College London. She joined Professor Ramesh Wigneshweraraj’s laboratory where she worked towards novel anti-microbial strategies by investigating the mechanisms of action of bacteriophage derived inhibitors of the bacterial RNA polymerase. After completing her PhD in 2012 she was keen to continue her interests and passion in transcription and virus-host interactions and was appointed as a post-doctoral researcher in Professor Finn Werner’s laboratory at University College London. Here she transitioned to the 3rd domain of life and characterised the first virus-encoded regulator of the archaeal RNA polymerase. She later extended her post-doctoral investigations by also exploring the transcription system of the MegaVirus ASFV. Carol joined the Barclay lab in April 2018 as a senior post-doctoral researcher where she aims to establish in vitro techniques to elucidate the mechanisms by which host cell factors regulate the influenza A virus RNA polymerase.


Dr Jay, Jie Zhou - Research Associate

Jie Zhou 

Jay received his PhD in Virology in 2017 from the centre of influenza research, school of public health, the University of Hong Kong. His PhD project is to define the aerosol particle size which can mediate the airborne transmission of influenza viruses and investigate related molecular determinants. During this time he also conducted an air sampling surveillance at the live poultry markets in Guangzhou, China. Jay has been a postdoctoral research associate at the Barclay’s since January 2018. He is participating in the “Collaboflu” project which aims to study the transmission modes and evolution of human influenza H3N2 viruses.



Dr Raul Yusef Sanchez David - Research Associate

Raul Sanchez

Raul received his PhD in Immunology in 2015 from the Paris Diderot University and the Institut Pasteur-Paris. His PhD project consisted in understanding virus sensing by the Rig-I Like Receptors (RLRs). RLRs are cytosolic pattern recognition receptors that sense viral RNAs and trigger innate immune pathways for the establishment of an inflammatory response in an infected tissue. During his PhD, he identified natural ligands of RLRs to viruses of positive and negative polarity.  In parallel, he was interested in how the RNA silencing machinery influenced RLR recognition of viral RNA. Raul joined the Barclay Lab in February 2018 as a Post-Doctoral Researcher. His current work mainly focuses on understanding how the RNA polymerase of influenza A virus is involved in viral pathogenesis in mammals.
