I have always enjoyed the outdoors and all aspects of the natural environment. During my schools years my love for biology really began to develop and as a result I enrolled for a B.Sc. Zoology degree at the University of Pretoria. My interest in research was sparked during this time which led me to apply for an honours programme examining the effects of animal-facilitated nutrient transfer across an aquatic-terrestrial interface. Thereafter I undertook a Master’s degree in the Hot Birds Research group under the supervision of Prof. Andrew McKechnie and Prof. Stephan Woodborne. This project focused on modelling bird responses to past, present and future climates. This included examining both acute and chronic heat exposure of birds in the Kalahari Desert. I have recently been awarded my Ph.D., which was supervised by Prof. McKechnie and two additional supervisors, Dr. Susan Cunningham and Prof. Blair Wolf. The aim of my Ph.D was to develop a novel, integrative modelling approach linking the thermal landscape, heat and water fluxes and behavioural decisions and trade-offs for desert bird species. Ultimately, I intend to construct detailed models of survival and reproduction in bird species, which reduces the need for detailed species-specific empirical datasets. 

Research Interests

 

My primary research interest concerns the role of climate change on species distributions. More specifically I am interested in how endotherms physiological performances are influenced by changes in climatic conditions. Further my interests extend to integrating eco-physiology and behavioural ecology with mechanistic, dynamic modelling techniques.

The natural world and all its wonders have always been of great interest to me. Birds in particular intrigued me from a young age. Some of my earliest memories involve me paging through bird guides attempting to memorise and learn what makes each species unique. This fascination evolved and grew over time and I am now privileged to be in a position where my passion for birds is merged with my professional ambitions. We have an incredible biosphere. I believe that improving our understanding of how avian communities contribute to the processes shaping and driving this biosphere we will be in a better position to conserve it.

Research interests

The composition of natural ecosystems and the processes which maintain these systems form a central interest of mine. For this reason, I pursued a degree in Zoology with a special interest in Ornithology and Ecology. My Honours and Masters degrees focused on avian landscape ecology, specifically assessing how anthropogenic landscape transformation affected forest bird assemblages. Avian population dynamics and their responses to disturbances in complex natural systems such as forest, woodlands, deserts etc. fascinate me. However, overtime it became apparent that in order to understand the functioning of natural systems, multi-disciplinary approaches are fundamentally important. By pursuing a PhD in physiological responses and adaptions to changes in climatic conditions across landscapes I am attempting to develop a platform from which I can make improved and strengthened inferences pertaining to how bird assemblages will be shaped by the inevitable changes within the landscapes and habitats in which they reside.
