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 works 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 Carol Sheppard - Research Associate

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.
