Dr Ruth Griffin

School/Department: Life Sciences, Pharmacy & Chemistry
Position: Lecturer In Biochemistry And Genetics

Biography

Ruth obtained her honours degree in Biological Sciences at Exeter University, specialising in Molecular Biology, then conducted her DPhil at Oxford University in Medical Molecular Microbiology funded by the MRC. Ruth's research focused on a vaccine antigen of the bacterium, Haemophilus influenzae, which causes childhood meningitis.
Following her DPhil, Ruth pursued postdoctoral positions at the National Institute for Medical Research (MRC) and at Imperial College researching new vaccines against a more threatening bacterial pathogen, Mycobacterium tuberculosis, which causes TB. She set up collaborations with scientists at Institut Pasteur and at Colorado State University which led to her securing funding from the NIH.
Keen to return to research in 2013 after taking a career break from 2007, an opportunity presented for Ruth to re-establish her research career at Kingston University working part time. During this time Ruth set up her vaccine research on another bacterium that causes meningitis, the meningococcus, otherwise known as Neisseria meningitidis and has made significant progress in designing and developing a novel vaccine. She has re-established a collaboration with the NRC in Canada and set up a collaboration with the University of Surrey. Ruth was appointed a full-time Lecturer in Biochemistry and Genetics in September 2015. Earlier that year Ruth wrote a PhD proposal to the Brazilian foundation Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) for her former undergraduate student, Ronni da Silva. After successfully obtaining this scholorship Ronni began his PhD at KU in November 2015. In addition Ruth supervises a Masters by Research student, Cansu Karyal who is funded by the Faculty.

Research Interests

I am passionate about designing and developing novel vaccines and therapeutics against diseases caused by pathogenic bacteria. My research in this field began with my undergraduate research project sponsored by GlaxoSmithKline. Since then I have researched different vaccine antigens of a number of pathogens including Mycobacterium tuberculosis which causes TB and both Haemophilus influenza and Neisseria meningitis (the meningococcus) which cause septicaemia and meningitis. I am currently researching the latter.
Several vaccines are available against most of the invasive-disease causing serogroups of N. meningitis however the need remains to develop improved vaccines effective against serogroup B strains. A breakthrough by Pfizer led to the licencing of the first serogroup B vaccine in the US in October 2014. This vaccine is composed of meningococcal Factor H binding protein (FHbp). Despite encouraging results to date, its ability to protect against diverse strains is being investigated. To this end, I am improving the protective efficacy of FHbp by conjugating this protein to specific lipid adjuvants known to enhance the breadth of protection of protein antigens.
In addition to applied research, I am passionate about more fundamental research, specifically elucidating the molecular pathway for the synthesis of vaccine antigens and this feeds into my vaccine research. I have identified key genes in the biosynthetic pathway for lipopolysaccharide in H. influenzae, in p-hydroxybenzoic acid in M. tuberculosis and in the lipidation and transportation of FHbp of N. meningitidis. This has been achieved by targeted mutagenesis of candidate genes and by random transposon mutagenesis with subsequent screening of transposon libraries. My PhD student is characterising a transposon mutant strain with increased susceptibility to killing by antibiotics. The protein encoded by the mutated gene is a potential novel drug target against the meningococcus. This research is timely with the alarming rise in antibiotic resistance and resulting need for alternatives to antibiotics.
