My current main research interest is the ontogeny of the innate immune system between species, the importance of SNP in innate immune receptors for ligand binding, and how we can use our knowledge regarding the innate immune system to design new/optimise existing vaccine strategies. Here, we are concentrating more on carbohydrate recogntion and carbohydrate-based vaccines.
After gaining a BSc.VetMed. (Veterinary University Hannover), my Dr.Med.Vet. thesis at the ETH Zuerich examined the impact of Bovine Leukaemia Virus infection on the ability of bovine macrophages to respond to LPS. This work was then followed by a stipend of the Swiss National Science Foundation (SNF) to participate in the PostGraduate course in Experimental Medicine, run by the University Hospital Zuerich. After a year, I returned to ETH Zuerich with a Postdoctoral Research Fellow Stipend of the German Research Foundation (DFG). This was followed by a Marie Curie Research Fellowship of the EU to join the group of Chris Howard at the Institute for Animal Health (Compton Laboratories) to work on the development and characterisation of dendritic cells and their role in respiratory syncytial virus infection. From here, I moved back to the ETH Zuerich as a Senior Scientist (Oberassistent). During this period I expanded the scope of my work to encompass the development of the innate immune system in ruminants, and aspect of pathogen escape mechanisms in innate immune cells. In 2001, I accepted an Assistant Professorship (Tenure Track) at the Institute of Virology (University of Berne), in the group of Thomas Jungi. In 2003, I accepted a Senior Lectureship at the 51³Ô¹ÏÍø, and was promoted to a personal tenured Chair and Professor in Molecular Immunology in 2007. The key motivation for this move was the unique opportunity to develop dendritic cell based vaccines for farm animals by targeting the then newly discovered class of innate immune receptors, such as the Toll-like receptors. In this role I have been responsible from the outset for the design, implementation and evaluation of new vaccine delivery platforms. These activities have attracted substantial funding and resulted of the submission of 3 different patent-applications. My research during this period has naturally been biased towards research administration, where close working relationships with industrial partners has been essential. Throughout, however, I have continued to make significant contributions to answering the function of the innate immune response in farm animals and evolutionary questions associated with identified differences between farm animals, human and mice. I have produced so far over 100 Peer Reviewed Publications in international journals across a broad range of empirical research topics such as that of the coevolution between host and pathogens, and the species-specific recognition of pathogens (Trends in Immunology). My current research is funded through BBSRC, EU (FP7 and EMIDA) as well as the Bill and Melinda Gates Foundation.

Efficacy testing of novel immersion and oral vaccines for Aeromonas hydrophila in Tilapia and Vietnamese catfish
Scientists are testing the efficacy of novel vaccines that can be easily administered to farmed fish without the need for highly trained personnel and specialist equipment. Over 30 species are currently farmed, including tilapia and Pangasius (Vietnamese catfish also known as Tra catfish). These fish species are farmed in low and middle-income countries (LMICs) and provide an important source of revenue for many low-income families, supplying both the domestic and export market.

Interaction of methanogens with the immune system
Globally, around 32 percent of global human-induced methane emissions come from livestock, mainly from enteric fermentation and manure management systems. Recent meta-analysis identified that the main intervention to reduce enteric methane production is by direct impacting methanogenic Archaea in the rumen that produce it. Vaccines offer a great potential since they don’t require direct and frequent access to the animals. However, with vaccination, we are faced with diverse problems, the main one being our lack of understanding if and how rumen microorganisms, and more specifically methanogenic archaea, are detected and potentially controlled by the immune system of the animal. The rumen and the large intestine of ruminants are quickly colonized during and after birth by methanogenic archaea and the processes occurring during this colonization over the first weeks of life are critical to understand their recognition by the developing immune system of the animal. This major gap of knowledge needs to be closed before we can fully develop an immunization strategy.

LEPTIMMUNHOST
Leptospirosis is a zoonotic disease due to motile Spirochete bacteria. All vertebrates can be infected with pathogenic Leptospira species, such as Leptospira interrogans (L.i) that is responsible for the more severe forms of disease. Different mammals present various disease symptoms and susceptibility, which is puzzling and not understood. For example, rats and mice are asymptomatic renal carriers of leptospires, cattle suffer morbidity and abortions, whereas humans and hamsters can die from acute leptospirosis. Prevalence of leptospirosis is high in tropical and subtropical areas, and in low-income countries with poor sanitation, where seasonal rains and global warming favor the dissemination of leptospires via contaminated sewage. Despite its health and economic burden, leptospirosis is a reemerging neglected disease, but it is not even cited as such by the WHO.

Optimising response to oral yeast-based vaccines against coccidiosis in chickens
We aim to improve Saccharomyces cerevisiae as an oral vaccine vector platform for use with poultry, focusing on the economically significant disease coccidiosis. We have developed a yeast-delivery platform in which antigens from Eimeria can be expressed in a stable, non-secreted form, with the yeast itself acting as transport system and adjuvant.

Protecting Pigs From Enzootic Pneumonia: Rational Design Of Safe Attenuated Vaccines (EPEDC)
Mycoplasma Hyopneumoniae (M.hyop) is a major worldwide pathogen in the pig industry that is the cause of enzootic pneumonia. Current vaccines are all based on inactivated or subunit approaches but fail to prevent circulation of the pathogen. Evidence from vaccines to other Mycoplasma species, e.g. M.gallisepticum vaccines in chickens suggests that live vaccines can be extremely effective at preventing disease spread. Barriers towards implementation of this type of vaccine for M.hyop include the lack of suitable strains that are sufficiently immunogenic without causing disease. One solution to this problem would be identification genes which contribute towards the pathogenesis of the bacteria as a basis to identify strains suitable to form the basis for new vaccines.

SweetAnimals
The SweetAnimal project studies the presence of sugar-binding receptors in the genomes of a variety of farmed animals, how these differ between species, what ligands expressed on pathogens they bind, and how this information can be used to develop carbohydrate-based vaccines.
