2008 - 2013   Junior group leader, University of Lausanne, Switzerland, with funding from the Swiss NSF to investigate the ‘Importance of mitochondrial uncoupling and telomere dynamics in the free radical theory of ageing’.

2005 - 2008    Post-doctoral fellow in the groups of Prof Pat Monaghan and Prof Neil Metcalfe, investigating telomere dynamics and ageing in birds. University of Glasgow. Fellowship funded by the Swiss National Science Foundation.

2004- 2005     Post-doctoral research associate in Dr Philipp Heeb’s group, investigating the role of skin UV coloration in parent-offspring interaction. University of Lausanne, Switzerland.

2000 - 2003    Ph.D. University of Berne, Switzerland entitled ‘Costs of parasitism and host anti-parasite strategies: Case studies in the Alpine swift Apus melba in response to infestation by the louse fly Crataerina melbae’ and supervised by Prof Heinz Richner and Prof Alexandre Roulin.

Current Research

The common thread that runs through my different research topics is the mitochondrion.

Mitochondria are small organelles present in most animal cells that are responsible to convert food into cellular energy. Hence, mitochondria functions are vital to support growth, reproduction and body maintenance, and ultimately for a healthy living. My current research aims to better understand (1) the sources of variation in mitochondrial function and (2)their consequences at the phenotypic level.

1. Sources of variation in mitochondrial function

A fascinating aspect of mitochondria biology is that they possess their own genome that is inherited through the mother only, whereas the nuclear genome is inherited from both parents. Because ultimately mitochondrial function relies on a ‘machinery’ with pieces that are encoded both in the mitochondrial and nuclear genomes, key questions are whether some mito-nuclear genome combination leads to more efficient/deficient mitochondria, and whether epigenetic interaction between these two genomes helps resolve conflicts.

To address these questions, I have developed a unique study system of four experimental lines of wild-derived voles with distinct combinations of mitochondrial and nuclear genomes (nuclearmitochondrial: CC, CW, WC, WW). This is allowing me to perform the most comprehensive study so far in a mammal species on effects of these two genomes on traits ranging from epigenetic variation in the mitochondrial and nuclear genomes and mitochondrial functions to the whole organism metabolism and metabolic health.

2. Linking mitochondrial function to the phenotype

Mitochondria & life history theories

Life histories describe how organisms grow, mature, reproduce and age, and substantial evidence has now accumulated that most of the variation in life histories of mammals and birds falls along a slow-fast continuum. Organisms with slow paces of life are characterised by slow growth, delayed maturity, low reproductive investments and extended lifespan, whereas organisms with fast paces of life possess the opposite combination of traits. The absence of alternative combinations of these traits implies constraints on the diversification of life histories. Besides the production of cellular energy vital to ensure growth, reproduction and maintenance, mitochondria are also producing reactive oxygen production (ROS) that can damage the cell and hasten ageing. Hence, variation in mitochondrial function may play a key role in shaping animal life history trajectories.

I am investigating the links between mitochondria, oxidative stress and life history trajectories in various animal species, both in the lab and in the field.

Mitochondria & behavioural and cognitive traits

Inter-individual variation in cognitive abilities, such as learning, has been related to variation in reproductive success in the wild. However, whether learning has a causal influence on reproductive success is an open question. Notably, it remains unclear how ageing, cognition and reproductive performance are inter-connected. Dysfunction in mitochondrial function with age can lead to a gradual accumulation of oxidative damage in the brain and muscles, which in turn may account for a spurious association between cognitive abilities and (reproductive) performance. A causal association between cognitive abilities and reproductive performance can arise through a better exploitation of the habitat. Because dietary antioxidants can mitigate cognitive ageing and improve reproduction, an alternative hypothesis is that cognitive abilities are key attributes allowing individuals to better exploit their habitat, increase reproductive success and live longer and healthier.

I am addressing this topic by measuring mitochondrial function, oxidative stress, cognitive abilities and reproductive performance in wild bird populations.
