Biography

Biography

Professor Marcello Riggio graduated from the University of Leicester with a BSc (Hons) degree in Chemistry-with-Biochemistry in July 1983. In May 1984 he took up a position as a Research Technician at the Beatson Institute for Cancer Research in Glasgow, working on oncogene expression and regulation. In April 1986 he took up a position as a Research Assistant in the Department of Veterinary Pathology at Glasgow Vet School, working on the development of recombinant equine herpesvirus vaccines, and studied for his PhD at the same time.

He obtained his PhD in 1991 and carried out his first postdoctoral position in the same department on equine herpesvirus vaccine development. In February 1994 he moved to Glasgow Dental School to take up a position as a Postdoctoral Research Fellow, where his immediate task was to establish a molecular microbiology laboratory and undertake novel research into oral diseases. In April 1995 he was appointed to a Lectureship in Molecular Biology, was promoted to Senior Lecturer in Molecular Microbiology in August 2002 and to Professor of Comparative Oral Microbiology in August 2021.

Current and previous roles

Professor Marcello Riggio is Professor of Oral Microbiology and is an integral member and group lead (Comparative Oral Sciences) within the Oral Sciences Research Group at the Dental School (University of Glasgow), which forms part of the School of Medicine. He has published in excess of 70 peer-reviewed papers, principally in the area of microbial ecology associate with human oral and systemic health and disease and oral diseases of animals. His main research focus is on oral diseases of animals (cats, horses, dogs, cattle). Most of this research involves active collaborations with colleagues in academia and industry in the UK (e.g., University of Glasgow; University of Edinburgh; University of Surrey; University of Liverpool; Fixed Phage; Carus Animal Health) and internationally (e.g., University of Amsterdam; Universidade Federale de Goiás, Goiânia, Goiás, Brazil;  UNESP, Araçatuba, Sao Paulo, Brazil; Nestlé Purina, USA).

In addition to his research portfolio, Dr Riggio has had a series of roles within the University of Glasgow linked to postgraduate management and teaching. He was Postgraduate Convenor (Dental School) from 2008-2014, overseeing all aspects of postgraduate research student administration and welfare (annual progress reviews, organisation of examining committees, pastoral support). He also served as Deputy Director of Postgraduate Dental Education (Dental School) from 2009-2014, contributing to the wider management and recruitment of students to the postgraduate dental taught programmes. From 2011 to 2016 he served as Deputy Postgraduate Convenor (School of Medicine), contributing to the management and assessment of postgraduate research students within the School of Medicine, the largest school within the College of MVLS. He has represented the Dental School on a number of University committees dealing with postgraduate student administration and is currently a member of Senate. He has also served on several committees within the Dental School (Postgraduate Management Committee; Research Committee; Information Services Committee; BDS1 Teaching Committee; BDS1 Staff-Student Liaison Committee).

In addition to his undergraduate teaching duties, he was leader of the Dental Postgraduate Taught (PGT) Core Course from 2009 to 2016, a course that formed the first year of study for all students studying on dental postgraduate taught courses. He has served as Deputy Lead and course lead for several courses in the MSc in Oral Sciences PGT programme. His is currently Education Lead for the Biological and Medical Sciences (BAMS) section at the Dental School.

Professor Riggio serves on several national and international committees influential in dental research and teaching. He served as Councillor (2012-2016) and Membership Secretary (2016 onwards )on the management committee of the Association for Sciences Educators in Dentistry (ASEiD). He has had numerous roles within the British Division of the International Association for Dental Research (IADR), which is also known as the British Society for Oral and Dental Research (BSODR): Councillor (2010-2013), Webmaster (2012 onwards), Honorary Secretary (2014-2019), President (2019-2021) and Immediate Past President (2021-2023). He serves on the IADR Council (its governing body) and represents BSODR on the Board of Directors of the Pan European Region (PER) of IADR and is amember of the Management Committee of PER-IADR. This influential role in UK dental research involves interaction with many bodies allied to dental research at national and international level. He served as Secretary/Treasurer of the Oral Microbiology & Immunology Group (OMIG) of BSODR (2008-2020) and previously served as a Councillor on the OMIG management committee (2005-2008). Professor Riggio was Chairman of the Local Organising Committee for the BSODR conference, which was held in Glasgow in September 2009 and has organised numerous other research meetings on an annual basis for OMIG and BSODR.

Professor Riggio has held roles as External Examiner for undergraduate and postgraduate taught dental degrees at the University of Bristol (2010-2015), University of Liverpool (2011-2015), Cardiff University (2015-2020), Queen Mary University of London (2018-2022) and University of Surrey (2020-2024). He has also acted as External Examiner for higher degrees (15 PhD, one DDent).

He has served as Editor (2011-2016) and Senior Editor (2016-2021) for the Journal of Medical Microbiology.

 

 

Research interests

Research interests

Professor Riggio’s main research theme is to identify the bacteria involved in inflammatory oral and systemic diseases in animals. This is now being achieved next generation (high throughput) sequencing of bacterial 16S rRNA genes in order to provide far greater depth, coverage, accuracy and sensitivity than that offered by Sanger sequencing in assessing the composition of complex microbial communities, uncovering microbial diversities that are orders of magnitude higher than revealed by previous sequencing technologies.

This research, in collaboration with academic colleagues at University of Glasgow, University of Surrey, Universidade Federale de Goiás, Brazil;  UNESP, Araçatuba, Sao Paulo, Brazil and with industrial partners (Fixed Phage; Carus Animal Health; Nestle Purina) is to understand the microbial ecology of oral health and disease in animals (cats, dogs, horses, cattle. He is also determining the nature of host-pathogen interactions in disease, particularly by assessing the innate immune response to infection. In vitro and ex vivo model systems are being used to further understand the host-pathogen relationship in disease. Future studies will seek to adopt a combined ‘omics’ approach to understanding more fully the underlying processes associated with oral and systemic diseases in animals.
