I am an evolutionary biologist. I study how animals (specifically, insects and land snails) diverge and adapt. I am particularly interested in rapid evolution, either in natural situations or in situations that have been influenced by humans. I work both in the field and in the lab, and where possible I make use of that unique research tool: our natural history collection.

My main motivation is the incredible diversity of life. In my research I study the processes that have driven (and are still driving) that diversification.

The biodiversity we see around us today is not static. It is constantly changing, evolving. Species diversify or go extinct. Their distributions and their niches change as does their appearance. Various processes of natura and sexual selection are responsible for these changes, some of which are accelerated today, as we humans create changes in the environment that set up novel selection regimes. In my research, my students and I study cases of rapid evolutionary change and diversification in wild organisms.

Evolution of endemism

Endemic species are the cherries on biodiversity's cake. Species that occur only in a small area are vulnerable and therefore have a high priority for conservation. they also give an insight into the processes of extinction (if they are ancient endemics)…

Rapid Evolution in the Anthropocene

Rapid evolution takes place when there are drastic changes in the environment which drives species' adaptation. These days, humans are the chief cause for such drastic environmental changes. I run a number of research projects to understand how such HIREC…

Left hand, right hand

Chirality is the phenomenon that, like hands, asymmetric objects can come in two mirror-image forms. Many organs and entire organisms are asymmetric. However, in most species, only one of the two mirror-images actually exists. In snails, for example,…
