Our Mission
Our aim is to determine the molecular mechanism(s) that prolong health during aging, using the nematode C. elegans, in order to develop novel strategies to treat age-related pathologies.
Global Challenge
Age-dependent diseases
By 2030 almost every fourth person will be 65 or older in Switzerland, Europe, and USA. Since old age is the main risk factor for developing cancer, neurodegenerative, cardiovascular, and metabolic diseases, as well as other age-related pathologies, the growing elderly population poses an immense social and financial challenge.

Strategic Goal
To identify novel strategies to improve human healthspan.
Using C. elegans as a pioneering system to model the aging process because of its ease for genetic manipulation, high evolutionary conservation of genes implicated in human diseases, and short lifespan (3 weeks). Importantly, using C. elegans lifespan assays as a read-out for extension of healthspan is a tractable and fast approach for discovering novel mechanisms that confer healthy aging. Several fundamental mechanisms discovered in C. elegans have been shown to delay age-related pathologies in higher organisms, such as mice, and these mechanisms have major implications for humans aging. Hence, by using C. elegans to model the aging process we could rapidly identify strategies to improve human healthspan.
Research
Currently, the lab focuses on exploring a novel and exciting mechanism that promotes healthy aging.
Our recent work has shown that many health- and longevity-promoting interventions re-activate the expression of extracellular matrix (ECM) genes during aging (Ewald et al., Nature 2015, PMID:25517099). This ECM enhancement is required and sufficient for extending the lifespan of C. elegans. Our research efforts are focusing on exploring the mechanism(s) of how prolonged ECM homeostasis promotes healthy aging. [read more] [pdf]
Our core competencies are:
- Aging research
- Extracellular matrix biology
- Molecular biology, genetics, and neuroscience
Our technical expertise with using the model organism C. elegans are:
- Automated lifespan assessment using the lifespan machine.
- High-throughput screening with genetic manipulations and chemical compounds for aging research.
- Neuronal plasticity (learning) assays.
Experimental advantage for using C. elegans- No animal safety or ethical issues: For FSVO, C. elegans not defined as an animal
- 60-80% of genes conserved with humans
- multicellular and eukaryotic
- C. elegans ages similar to humans, but faster (lifespan of 3 weeks)
- scalable for high-throughput genetic and drug screens
