Profile

Professor Rob Allaker holds a BSc (Hons) in Applied Biological Sciences (1982) and a PhD (1986) in Skin
& Oral Microbiology from the University of the West of England, Bristol. He joined the Royal Veterinary College
in 1986 as a Wellcome Trust Post
-Doctoral Research Fellow.

He then joined Queen Mary University of London (QMUL) as a lecturer in 1992, was promoted to Senior Lecturer

in 2002, Reader in 2006 and took the title of Professor of Mucocutaneous Microbiology in 2011. He was secretary to the Oral Microbiology & Immunology Group, British Division of the International Association for Dental Research (IADR) for 6 years. He holds a Principal Investigator post at QMUL and currently works with a number of companies with interests in oral care and materials, including GlaxoSmithKline (GSK) and Johnson Matthey. He has acted as a London Technology Network Business Fellow to help facilitate the transfer of technology-enabled innovations from QMUL to Industry. In 2010, he was awarded the IADR/GSK Innovation in Oral Care Award.

Professor Allaker is an author on over 90 publications in peer reviewed journals and books, and has supervised over 50 researchers. He is a section editor for the International Journal of Antimicrobial Agents.

In 2019 he was made a Fellow of the International Society of Antimicrobial Chemotherapy in recognition for
outstanding contributions to the field of antimicrobial chemotherapy. He has served on the management committee of the British Society for Oral and Dental Research (BSODR). Since 2013 he has been Director of Graduate Studies for the Institute of Dentistry.

Teaching


Professor Allaker is a Fellow of the Higher Education Academy and teaches a wide range of microbiology topics
at both the undergraduate and postgraduate levels on QMUL and external courses. He was on the management
committee of the Association of Basic Science Teachers in Dentistry, Society for General Microbiology Education
& Training Group and British Society for Oral and Dental Research.

Research

Research Interests:

 
Host - microbial interactions and antimicrobial research have provided the focus for Professor Allaker's
research career since 1982 with an emphasis on the microflora of the oral cavity and skin. 

At PhD and Post-Doctoral levels, studies centred on the virulence capabilities of Propionibacterium and
Staphylococcus spp. At QMUL, the role of innate immune mechanisms in the control of microbial populations has been under investigation. These include those centred on the entero-salivary circulation of nitrate which
encourages nitrate reducing bacteria (NRB) to reside within the oral cavity. Whereby, immunity may be enhanced via the action of microbial nitrate reductases and the subsequent production of nitric oxide (NO) from nitrite under acidic conditions. This theory has been examined in relation to dental caries and periodontitis.  In oral microbiome studies, the stability of the tongue microflora, particularly the NRB has been shown to be associated with oral health. These studies also complement Industry funded projects to determine the role of volatile compound producing tongue bacteria in oral malodour and periodontitis.


The use of nano-antimicrobials and copper-bearing alloys to prevent implant infection is being explored in
collaboration with the Institute of Metal Research in China and Industry. Alongside clinical colleagues, the
oral microbial profile of patients with neutrophil defects, metabolic syndrome, rheumatoid arthritis and
periodontal bony lesions is under investigation. A major project funded by the Medical Research Council,
involving collaboration with the Blizard Institute, commenced in 2020 to examine the impact of microbial and
inflammatory exposures at oral and other sites on birth outcomes in rural Zimbabwe.
