100%, Zurich, fixed-term
The ETH Zurich Laboratory of Epigenetics, Nutrition and Metabolism and the Sustainable Food Processing Group in the Department of Health Science and Technology are collaborating on a strategic research initiative focused on Microalgae and Plant-Based Foods in Human Nutrition and Health. The Sustainable Food Processing Group emphasizes a systemic approach to food production, taking into account societal needs and their environmental, economic, and social impacts. Innovative raw materials are explored within urban farming and processing concepts to enable sustainable food supply solutions.
The Laboratory of Epigenetics, Nutrition and Metabolism seeks to unravel the intricate relationships between nutrition, metabolism, and the epigenome through advanced methodologies, including single-cell and next-generation sequencing, as well as human and murine in vivo and in vitro studies. We are currently seeking a talented and highly motivated doctoral student to investigate novel mineral sources for treating micronutrient deficiencies in humans, with a focus on the absorption and bioavailability of these mineral sources in clinical trials.
Micronutrient deficiency is a pressing global health challenge, largely due to inadequate dietary intake. It is estimated that over 5 billion people do not consume sufficient amounts of at least one micronutrient. Mineral deficiencies—particularly of iron, calcium, zinc, and magnesium—are widespread, especially in low- and middle-income countries, impacting women and children the most due to low-mineral diets.
Dietary minerals are typically sourced from a variety of foods, including animal products such as meat, dairy, and seafood, as well as plant-based foods like legumes, cereals, nuts, seeds, and leafy vegetables. However, the reliance on traditional animal-based foods raises concerns about environmental sustainability, ethical issues, and dietary preferences. While plant-based foods are generally more sustainable, they often contain lower levels of minerals and may have reduced bioaccessibility and bioavailability due to absorption inhibitors such as phytates and polyphenols. This necessitates the exploration of alternative, more sustainable, and mineral-rich food sources that can effectively address global mineral deficiencies.
Novel mineral sources, such as microalgae, are promising candidates for supplying essential minerals, including iron, calcium, zinc, and magnesium, alongside proteins, lipids, vitamins, and other bioactive compounds. However, it is crucial to assess the bioavailability of these minerals through in vivo clinical trials before large-scale applications in human populations.
As a doctoral student, you will be responsible for conducting research aimed at exploring the absorption and bioavailability of novel mineral sources through clinical trials.
You will be part of a leading research team focused on Microalgae and Plant-Based Foods in Human Nutrition and Health, supported by both ETH groups. You will have access to state-of-the-art research equipment in an excellent working environment. ETH Zurich and the team offer outstanding training opportunities for career development and strong networks in sustainable food and nutrition. Research assistants will be available to support the project as needed.
Living expenses will be covered with a fixed-rate standard monthly doctoral student salary according to ETH guidelines.
