Personal profile

Research Focus

My research is deeply rooted in life history theory and, using cutting edge phylogenetic comparative approaches, I investigate fundamental questions on the evolution of reproductive strategies, the tradeoff between self maintenance and reproduction, and how different life history strategies affect population growth. Specifically, I am interested in:

  • Reproductive strategies: how traits, such as diversity in parental care and placental morphology, influence life history evolution;
  • Sleep ecology and evolution: how sleep is related to the tradeoff between self maintenance and reproduction;
  • Biological invasions: how life history strategies facilitate population growth from small sizes in alien species.

Beyond these research areas, I collaborate on studies in a diversity of organisms - ranging from jellyfish to vertebrates - and research areas, including the evolution of hermaphroditism, the scaling of metabolic rates, brain evolution, and the role of evolutionary history in ecotoxicological studies.

(1) Biological invasions

I am particularly interested in the core question in ecology of how small populations grow from small numbers, a process that is central to speciation, island colonisation, metapopulations, and key to applied problems like reintroductions of threatened species, fragmentation of native populations due to anthropogenic disturbance (e.g. due to habitat alteration), population recovery following a decline, alien population establishment and spread, or the management of zoo populations. Alien populations are ideal models for this question, as they typically start small. We show that successful alien mammal, amphibian and reptile species are characterised by high reproductive rates, which help them boost population growth and reach quickly the size at which the driver of extinction of small populations become negligible. This research in  has been funded externally by NERC (New Investigator, 2014-7).

(2) Reproduction and Parental Care

Parental care has attracted much research attention as it is core to the fitness of parents and offspring, it is expected to alter a species’ life history strategy, and to lead to sexual conflict and parent-offspring conflict. I investigate the drivers of the evolutionary origin and maintenance of parental care and the relationship with life histories across species. We show that energetically expensive male care forms in mammals, such as  provisioning the mother or carrying heavy offspring, boosts maternal fecundity but does not help increase offspring weight. In amphibians, we find that parental care evolves in a step by step process, but prolonged care from the egg to the tadpole and juvenile statge can be easily lost. Moreover, we demonstrate that biparental care in amphibians is evolutionarily labile, even with division of labour between the parents.

The placenta is fundamental in mammalian reproduction and is one of the most diverse organs between mammals species. While there is much research on the clinical and physiological aspects of placental structure in human and farm animals, we know very little about how the diversity in placental morphology among species evolved and whether it has any implications for their reproductive strategies. My work reveals the importance of differences in placental structure for a species' life history strategies and how this is affected by parent offspring conflict. This research has been funded externally by NERC and BBSRC.

(3) Sleep ecology and evolution

Sleep is essential for animals. Lack of sleep can impair cognitive abilities and brain functioning, and undermine immune functions. Daily sleep time and how sleep is accommodated within the 24 hours cycle varies remarkably between species, but why this is so is poorly understood. My work has led to fundamental insights how ecology drives the evolution of diversity in sleep times and patterns in mammals, revealing the key influence of predation risk and the tight relationship between sleep, immunity and parasites.
