Career posts in more detail

A Professor of Veterinary Medicine and Head of Bristol University Clinical Veterinary School

1990 - present

Budget holder and "Chief Executive " of one of Europe's leading Clinical Veterinary Schools. Soon after taking up this post in 1990 I embarked on a radical reorganisation of the Clinical Veterinary School which up to that moment was a collection of disparate and relatively small departments. The Clinical School at Bristol now consists of nearly 200 staff (academic and support), together with over 50 post graduate students studying for a Ph.D (many from overseas) and between 70-80 Veterinary undergraduates in every year of a 5 year course. The reorganisation resulted in a single Department of Clinical Veterinary Science with four academic divisions:

Animal Health and Husbandry

Companion Animals

Food Animal Science

Molecular and Cellular Biology

The Veterinary School is assessed by the public, the academic community and our paymasters (HEFC) on the basis of three "outputs". These outputs are: teaching, research and clinical work. Within the new structure formed at Bristol Veterinary School these three "outputs" formed the basis of three major matrix committees that have both financial and organisational matters delegated to them:

Teaching Committee

Research Committee

Hospital Committee

The reorganisation at Bristol Veterinary School also involved a major building expansion including:

New Small Animal Hospital (one of the largest in the UK)

New Equine Diagnostic Centre (serving the south west, Wales and central England).

New lecture theatres

Extensive computerisation and networking of site.

I have been responsible for heading-up all these projects and developments including the initial planning, production of detailed business plans, securing funding, selection of contractors etc.

The main duties of my current post can be summarised:

a) Responsible to the Vice Chancellor of Bristol University for the annual budget of the Department, currently just over 10 million per annum

b) Co-ordinating the securement of over 3.5 million per annum for research within the Department

c) Overall responsibility for delivering an effective course to Veterinary undergraduates

d) Providing academic leadership to the Clinical Veterinary School

e) Overall responsibility for the management and career develpoment of nearly 200 academic and support staff

Current annual salary is 43,442 together with the British Universities contributory superannuation scheme (USS).


B Deputy Head of Cambridge University Veterinary School, Lecturer, Official Fellow and Senior Tutor, University of Cambridge

My ten year period of work at Cambridge Veterinary School combined a research and teaching career as a lecturer, a College career as Official Fellow and Senior Tutor and in the last few years a management career as Deputy Head of Cambridge Veterinary School. My research group included both overseas post graduate students and experimental work on diseases found in East and Central Africa (eg East Coast Fever and Trypanosomiasis). My position as Senior Tutor gave me the major responsibility for the selection, processing and overseeing of all the post graduate students, the majority of whom were from overseas.

I left Cambridge University on appointment to a Chair at Bristol University.


C Senior Research Associate, Department of Pathology, University of Cambridge

This was a three year full-time research post taken up after my initial return from the six years work in East Africa. The work was funded by the Wellcome Trust and Agricultural Research Council.

I left to take up a tenured position within Cambridge University.


D Immunologist at the Kenyan National Veterinary Research Laboratory

For the first three years in Kenya I was employed by the FAO of the United Nations as team leader in immunology within a project investigating the prevalence of tick-borne diseases within Kenya. The work also involved training of both professional and support staff including training abroad for a number of Kenyan staff.

The following three years of work funded by the British Government concentrated on developing the immunology laboratory at the Veterinary Research Centre and establishing a number of diagnostic tests etc. for use in the field and laboratory.

I left this job to return to an academic career in Britain.


Teaching Responsibilities and Experience


a) Lecturing

Veterinary Immunology

An applied course given to veterinary students after their basic immunology course in the Medical Science Tripos.


A course given to veterinary students before they begin their species medicine courses, and intended to introduce the concepts of epidemiology and disease control.

Cattle Medicine

Lectures forming part of the combined cattle course. Subjects covered include all neonatal calf diseases, enzootic calf pneumonia, salmenellosis, respiratory disease in adults, gastro-intestinal diseases in adults and fluid therapy.

Comparative Immunology

A short course given to pre-clinical veterinary, medical and natural science students.


b) Clinical and practical teaching

Small group teaching in clinical examination, preventative medicine, the use and application of computer-based (eg Daisy) programmes and immune-mediated diseases.

c) Examining

Assessor, Examiner and Chairman of Examiners for all medical subjects in the Final Veterinary Examination at the University of Cambridge and Bristol.


I have personally supervised 12 PhD students comprising individuals from both both home and overseas (including one from Kenya). I have also examined several PhD dissertations for the Universities of Bristol, Cambridge, Edinburgh, Liverpool, Glasgow and London.


Research Interests 

My research group consisted of post-doctoral workers, research assistants, Ph.D.students, laboratory technicians and animal technicians, together with a regular number of visiting scientists. Over the last ten years my research has been focused in the following main areas:

1. A study on the immune response against helminth and nematode parasites

This includes studying the eosinophil-mediated antibody-dependent destruction of parasites; the isotype and sub-isotype of antibody responsible; the influence of mediators such as ECF-A and interleukins; the characterisation and biological activity of granule contents from eosinophils and neutrophils, especially cationic proteins; and purification of surface antigens from the parasites both to provide sensitive and specific serological assays, as well as possible immunogens for vaccination.

2. A research project involving both basic and applied immunology to study the defense mechanisms of the calf respiratory tract and its importance in enzootic pneumonia of calves

This includes working on viruses such as BHV1, PI3 and RSV; producing highly sensitive ELISA tests for each virus; examining the potential of calf leucocytes to destroy virus infected targets in both antibody-dependent (ADCC) and antibody-independent (CTL and NK) assays; and producing a sensitive and reliable 3H-uridine incorporation assay for bovine interferon (IFN).

3. A study of the anti-viral and immunomodulating effects of recombinant bovine IFNa, IFNg and tumour necrosis factor (TNF)

These recombinant lymphokines and monokines are assessed in vitro for their effect on the recruitment and activation of bovine NK cells. Experiments are also done on delivery systems in vivo to induce high levels of anti-viral activity in the upper and lower respiratory system of calves following inhalation of an aerosol of IFNa. Some of this work has involved the study of individual field cases and outbreaks in an effort to bridge the gap between laboratory based research, the actual disease problem itself and the needs (diagnostic and therapeutic) of the clinicians.

4. Equine Herpes Virus (EHV1) and foal immunology

A major part of the research effort of my group was in the area of producing SPF (EHV1 free) foals and establishing a totally susceptible equine model for EHV1 infection. Various recombinant and purified glycoprotein preparations tested by various routes for their potential as candidate vaccines.

In addition, the IFN response and isotype and sub-isotype antibody response in serum and nasal mucous in response to EHV1 infection was studied. At the cellular level specific T cell transformation, NK activity and neutrophil-mediated antibody-dependent cytotoxicity (ADCC) were also studied. All these parameters are included in a battery of assays in an additional study on the development of immune competence in the neonatal foal.

5. Monoclonal antibodies

A panel of monoclonal antibodies (Mabs) have been made against canine lymphocytes and a retrovirus-infected canine lymphoid cell line. In addition the canine NK cell assay has been established using the latter target, and was studied in a series of clinical tumour cases.

A panel of Mabs has also been recently made against canine IgG sub-isotypes. In addition another panel of Mabs has been produced against equine lymphocytes and equine immunoglobulins.

6. Use of Bovine Hyperimmune Colostrum for Treatment and Prevention of Disease

Techniques have been evolved to hyperimmunize cattle against selected pathogens from both domestic animal and human diseases. Assays have been developed to quantify the specific immunoglobulin content of the colostral preparations as well as assessing the anti-pathogen activity of the samples in patients (eg in AIDS patients suffering from cryptosporidial infection).

7. AFRC link programme with the Institute of Animal Physiology, Babraham

This link programme studied the role and fate of the large population of null T lymphocytes in the young pig. This work was firstly on their potential differentiation pathways using a combination of Mabs and cDNA probes; secondly on their functional role in assays such as NK cell killing; thirdly on their origins, phenotypic changes and migration in vivo.

8. Innovative Vaccines

A molecular biological approach to developing an innovative approach to vaccination of cattle involving a recombinant herpes viral vector with insertion sites for both bovine cytokine genes as well as individual pathogen genes.
