PhD Position in Metabolic Discovery and Mechanistic Physiology using Exhalomics in Dairy Cows
Location: 100%, Zurich, fixed-term
The Animal Nutrition group at ETH Zurich invites applications for a PhD position focused on the interface of ruminant nutrition, animal health, and physiological phenotyping using emerging non-invasive exhalomics (exhaled breath metabolomics). The research program integrates animal experiments with advanced analytical techniques and bioinformatics to enhance understanding and monitoring of physiological metabolism in dairy cows. The successful candidate will work within a dynamic research team led by Mutian Niu, benefiting from a state-of-the-art dairy research facility, a metabolic center, and high-resolution analytical platforms.
Project Background
The PhD student will engage in three major research components centered around exhalomics and its application to animal physiology and health:
- Nutrient Metabolism in Dairy Cows: Conduct controlled nutritional experiments to evaluate how dietary factors influence rumen function and metabolic responses.
- Immune Challenges and Early Detection of Health Perturbations: Perform immune-related animal experiments using LPS challenge to examine how inflammatory states alter metabolic signatures in dairy cows.
- Large-Scale Exhalomics in Dairy Cows: Carry out an observational study comparing exhaled-breath profiles of healthy and hospitalized animals.
Across all three components, the project will involve high-resolution mass-spectrometry and complementary data streams to explore how exhaled metabolites reflect physiological status.
Job Description
- Conduct in vivo/ in vitro experiments in collaboration with an experienced team.
- Perform physiological and metabolic sampling (rumen, breath, blood, fecal, urine, milk).
- Operate, integrate, extract, and interpret data from high-resolution mass spectrometry platforms.
- Organize, manage, and analyze large datasets including bioinformatics.
- Communicate scientific results in written and oral form, including conference presentations.
- Publish findings in peer-reviewed journals.
- Participate actively in group meetings and collaborative research discussions.
- Support other team members in their animal experiments/projects.
Profile
Required Qualifications
- Master's degree in Animal Science, Biology, Physiology, Veterinary Science, Biochemistry, Bioinformatics, or related fields.
- Ability to perform structured, well-documented experimental work.
- Strong motivation to work with animals.
- Curiosity for science.
- Good communication and teamwork skills.
- Proficient in English language.
Desired Skills (but not required)
- Experience with nutritional, immunological (LPS) or metabolic models in animals.
- Familiarity with laboratory techniques in biochemistry, metabolomics, or bioinformatics.
- Exposure to mass spectrometry or analytical chemistry tools.
- Statistical/data-science/bioinformatic tools.
Workplace
The workplace is set within a stimulating research environment in a prestigious institution equipped with state-of-the-art facilities and datasets.
We Offer
- A stimulating research environment in a world-leading institution, with access to state-of-the-art facilities and datasets.
