In particular, Jon is interested in addressing current clinical problems and knowledge gaps and transferring research findings to the dairy industry and veterinary profession.


Dr Jasmeet Kaler

Jasmeet is Associate Professor in Epidemiology and Farm Animal Health. She was named Young Animal Welfare Scientist of the year in 2015 by the Universities Federation of Animal Welfare for her research on lameness in sheep and she was also runners up for 2011 Scopus Young Researcher Award in Health and Medical Sciences awarded by Elsevier in association with the US/UK Fulbright Commission.

Jasmeet  currently holds grant portfolio of > £2.8M from BBSRC, Innovate UK and AHDB UK as Principal Investigator and had been integral contributor to the grant income of around £6M since joining Nottingham.   Her main area of research interest is the epidemiology of livestock diseases, which she explores through the use of big data, analysing patterns that can advance our understanding of livestock health, welfare and behaviour. Jasmeet is also Chair of the School’s Athena Swan SAT and Ruminant Population Health Strategic Research Area Leader.


Dr Chris Hudson

Chris is Clinical Associate Professor in Dairy Health and Promotion. Prior to joining us at The University of Nottingham in 2009, he trained and taught at the University of Bristol, where he gained an award for outstanding achievement in clinical teaching. He has also worked in a large mixed practice in Devon and is an RCVS Recognised Specialist in cattle health and production.

Here at Nottingham, Chris has completed a PhD on factors affecting reproductive performance in UK dairy herds. He has extensive experience of measuring and monitoring herd performance and is especially interested in strategies for improving herd-level fertility, the interactions between nutrition and reproductive performance, research that maximises routinely gathered data and opportunities to translate research into real industry impact.


Professor Andrew Bradley

Andrew is a part-time Professor in Dairy Production Medicine. He qualified as a vet at the University of Cambridge, working at a dairy practice before teaching and researching at the University of Bristol. An RCVS recognised specialist in cattle health and production and a European specialist in bovine health management, Andrew joined The University of Nottingham in 2009.

His primary area of research interest is bovine mastitis, extending into other areas of bovine production medicine. He has published widely on mastitis control and has a particular interest in dry period management. Andrew’s work also applies the latest molecular and analytical techniques to intractable clinical problems to maximise animal welfare and productivity.


Dr James Breen

James is  Associate Professor in Cattle Health and Production. He qualified as a veterinary surgeon at the University of Bristol in 1998 and joined Prof Martin Green working with companion and farm animals at the Orchard Veterinary Group, Glastonbury. He is an RCVS-recognised specialist in cattle health and production and has a PhD in cow risk factors for clinical mastitis and increased somatic cell count.

James worked with Dr Andrew Bradley and Prof Green on a national dairy cow mastitis research project and was involved in developing the national DairyCo mastitis control initiative. He completed a three-year residency in production animal medicine, and today divides his time between lecturing here at Nottingham, working in his own surgery and being a clinical associate at a commercial laboratory that provides milk recording services and mastitis consultancy.


Other researchers

Dr Fiona Lovatt

Fiona works part-time and is a Clinical Associate Professor here at the School of Veterinary Medicine and Science. She’s a past president of the Sheep Veterinary Society and an RCVS recognised specialist in sheep health and production.

Fiona is active member of sheep flock health research and collaborates with Dr Jasmeet Kaler and Dr Peers Davies on various sheep projects .

Fiona also runs a sheep veterinary consultancy business, Flock Health Ltd, which involves working with veterinary surgeons, students, farmers, processors, retailers and pharmaceutical companies throughout the sheep industry, both in the UK and internationally.


Dr Wendela Wapenaar  

Wendela is Clinical Associate Professor in Cattle Health and Epidemiology. An enthusiastic veterinary surgeon and scientist, she’s dedicated to translating her research findings into practical applications, on farm. She’s a diplomate of the American Board of Veterinary Practitioners, a named veterinary surgeon and a senior fellow of the Higher Education Academy. She received her PhD in Veterinary Epidemiology from the University of Prince Edward Island, Canada, in 2007.

Wendela’s specialist field is ruminant health and her research focuses on three key areas:

  • bovine infectious disease and vaccination
  • bovine reproduction and obstetrics
  • knowledge transfer

She also collaborates with other researchers to promote evidence-based veterinary medicine and educational research. 


Dr Peers Davies

Peers is Clinical Lecturer in Sheep Health and Production. He grew up on a sheep and beef farm in North Wales, graduating from the University of Cambridge in 2008 before working in farm animal practice in Devon and North Wales. In 2010, he established Pro-Ovine Sheep Veterinary Consultancy Ltd, providing expertise in sheep health, management and production systems to commercial sheep producers throughout the UK, Ireland and EU.

He has since completed a PhD is molecular epidemiology of S.uberis mastitis and become a resident of the European College of Small Ruminant Health Management. His principal research interest is production-limiting disease in sheep flocks – its impact on efficiency, cost of production and methods of control.


Dr Pete Down

Pete is Clinical Assistant Professor in Farm Animal Population Health. He graduated from the University of Bristol veterinary school in 2004 and worked as a general practitioner at a large mixed practice for almost six years before taking up a dairy residency here at the School of Veterinary Medicine and Science, combining clinical work at Scarsdale farm animal practice with research and undergraduate teaching.

In 2012, Pete began a PhD funded by the BBSRC and DairyCo, investigating decision-making around mastitis control in dairy cows. Today, he’s a European veterinary specialist in bovine health management. His research focuses on population health and welfare, in particular using the Bayesian decision-theoretic framework to evaluate and optimise decision-making for bovine mastitis control in the UK.
