Javier conducts applied research on a range of topics across the animal and human health spectrum, mostly focusing on zoonotic diseases and food safety. His work combines epidemiological studies in livestock and human populations and analysis of animal and public health surveillance data. Javier is involved in research in the UK, India, Rwanda, Jordan, Peru and Bolivia. Ongoing projects include:

• Modelling biological hazards in the dairy chains of Andhra Pradesh to inform food safety policy
• Control of brucellosis in dairy herds in Rwanda
• Design and testing of interventions to reduce MERS-CoV infection risk in Jordan
• Food safety, consumer preferences and governance in the supply of meat to urban markets in Peru
• Reducing COVID-19 transmission in food markets in Peru and Bolivia
• Improved decision making for control of Johne’s disease in UK dairy herds

Together with Prof. Joanne Webster, he is currently supporting FAO with the development of technical guidelines for the surveillance of endemic zoonoses in the animal source.

Javier is involved with undergraduate and postgraduate teaching in epidemiology, food safety and public health. He regularly contributes to international training courses and in the last 15 years, he has designed and taught courses in Eastern Europe, Asia, Africa, Latin America and the Caribbean. Javier co-led the OIE Veterinary Education Twinning Programme between the RVC and the Jordan University for Science and Technology, one of the first education twinning programs endorsed by the World Organisation for Animal Health (WOAH). He was involved in the design and delivery of the China Field Epidemiology Training Program for Veterinarians since its inception in 2011, contributing to the training of five cohorts of veterinary epidemiologists in China over a 10 year period. Between 2020 and 2023, Javier supported FAO with the development and implementation of  field epidemiology training programs for veterinarians in Jordan, Malaysia, Philippines and Turkey.

Javier is actively involved in promoting epidemiology and its potential contribution to public health with the general public through different outreach activities. He volunteers for the statisticians for society program of the Royal Statistical Society, currently supporting the Indoamerican Refugee and Migrant Organization (IRMO).

 

 

• AMFORA: Applying a One Health systems approach to formulate strategies for mitigating risk to human health of AMR in Aquaculture

  

  The aim of AMFORA is to use a ‘systems-thinking’ approach to map aquaculture systems and identify hotspots for the emergence and selection of resistance and human exposure to antimicrobials and antimicrobial-resistant organisms.

  This will enable the identification of potential drivers of AMU and interventions to reduce AMU.

• Control of brucellosis in dairy herds in Rwanda

  

  We are working with overseas partners to research the frequency and distribution of brucellosis among dairy herds, and longitudinal studies to identify Brucella species causing infection in dairy herds.

  Brucellosis is the world's most widespread zoonosis, imposing a substantial burden on the livelihoods of poor people as a result of human disease and reduced livestock productivity. However, brucellosis is rarely a priority for health systems and for this reason the WHO classifies brucellosis as a "neglected endemic zoonosis"

• Foodborne diseases and public health governance: Comparing food safety, consumer preferences and governance in the supply of meat to urban markets.

  

  Foodborne diseases are a major cause of morbidity, mortality and undernutrition including micronutrient deficiencies, with animal-derived food posing the highest risk for consumers in low and middle-income countries such as Peru. Traditional food markets are still the dominant distribution channel for locally produced food in developing countries and the main food source for most poor urban households. The research explores the safety of meat supplied through traditional food markets that serve poor urban consumers.

• Genetic and non-genetic factors in Campylobacter levels in poultry

  

  Researchers explored variation at specific positions in chickens’ genome and their association with Campylobacter in the birds’ guts. Campylobacteriosis exerts profound societal and economic costs to the UK and other countries. The World Health Organization has estimated that Campylobacter causes 95 million illnesses, 21,000 deaths and loss of 2.1 million disability-adjusted life years globally. In the UK alone, there were 63,946 laboratory-confirmed human cases in 2017.

  The study concluded that, although there are genetic factors that influence Campylobacter colonisation, these factors play a relatively minor role.

• Responding to the challenge of MERS-CoV: Development and testing of interventions to reduce risk among Bedouin populations in southern Jordan

  

  Middle Eastern Respiratory Syndrome coronavirus (MERS-CoV) is an emerging infectious disease first identified in Jordan and Saudi Arabia in 2012. Clinical cases present as an acute respiratory infection with rapid onset pneumonia and, in many cases, death.

  In this interdisciplinary research, we study the biological and sociocultural contexts of the disease among at-risk Bedouin populations in southern Jordan. In particular, we are seeking to understand which individuals, or camels, should be targeted for future vaccination, the correct seasons for the deployment of such vaccines and the sociocultural issues that are driving the infection.
