People

Sonia Kleindorfer – Founder & Principal Investigator

Professor Sonia Kleindorfer is a biologist with a strong interest in avian development and behaviour. She is an international expert on prenatal learning, studied with a range of methodologies including acoustic playbacks to developing birds in ovo, monitoring embryonic heart rate and brain transcriptomics, and measuring prenatal vocal learning. She has worked on the Galapagos Islands for 20+ years measuring evolutionary change in a lethal and rapidly evolving host-parasite system between nestling Darwin’s finches and Philornis downsi. She applies a gender-lens to research questions and studies female and male behaviour, with a special interest in behaviour shaped by early-life experience. Sonia’s Google Scholar Profile.

Diane Colombelli-Négrel – Principal Investigator

Dr Diane Colombelli-Négrel is behavioural ecologist with expertise in animal behaviour, prenatal learning, conservation and bio-acoustics. Her research (from seabirds to songbirds) identifies ecological and behavioural processes that influence population dynamics and evolutionary adaptation to environmental change. Her research has a strong community aspect to enhance local culture and benefit the broader society through research-integrated education. She is the only Penguin Ecologist in South Australia.

Andrew Katsis – Postdoctoral Fellow

Dr Andrew Katsis is a behavioural ecologist with an interest in songbird personality, vocal learning and prenatal communication. His current work centres on understanding the ecological importance of behavioural differences within species, using wild study populations of superb fairy-wrens and Darwin’s finches. Andrew is also an avid science communicator, and has contributed to magazines, online news, radio and television. In 2018, he appeared as a guest scientist on the Netflix series Bill Nye Saves the World. Andrew joined the BirdLab in 2019, after completing his PhD research at Deakin University.

Damian Tohl – Postdoctoral Fellow

Dr Damian Tohl is a member of the Video and Image Processing group at Flinders University, and a postdoctoral researcher with expertise in the fields of image processing, computing analysis and artificial intelligence. His main research interests include image enhancement and identification using digital images. Damian joined the BirdLab in 2019 and works on facial recognition in koalas, geese and penguins with Sonia Kleindorfer and Diane Colombelli-Négrel.

Lauren Common – PhD student

Lauren is a PhD student in the BirdLab under the supervision of Sonia Kleindorfer, Diane Colombelli-Négrel and Rachael Dudaniec on Philornis downsi, a parasitic fly introduced to the Galápagos Islands. Her project focuses on the novel co-evolutionary relationship between P. downsi and its Darwin’s finch hosts, and how this has changed over time from the parasite’s perspective. Lauren is investigating changes to the life history and population genomics of P. downsi since its introduction, examining the impact of invasion and natural selection on parasite populations and host-parasite interactions.

Alivereti Naikatani – PhD student

Alivereti is a PhD student enrolled at University of the South Pacific with adjunct supervision by Sonia Kleindorfer and Gunnar Keppel. He is interested in patterns and processes of niche partitioning in Fiji’s woodland birds. He applies a range of techniques to test his ideas including surveys to estimate avian abundance and density, observational data on foraging behaviour, and experimental approaches to measure territory defence. Previously, Alivereti has been senior technician at the South Pacific Regional Herbarium (SPRH) in Fiji and partner for the Flinders University and UniSA New Colombo Mobility Program.

Taylor Headland – PhD student

Taylor is a PhD student under the supervision of Diane Colombelli-Négrel, Sonia Kleindorfer, Petra Sumasgutner and Shane McPherson on the Nankeen Kestrel, a common and widespread Australian raptor. His project investigates the ecology of the Kestrel across the urban/rural gradient of South Australia, and how urbanisation impacts different aspects of the bird’s ecology. Taylor is exploring the abundance and distribution, foraging behaviours and success, health status, spatial patterns of movement and nesting success of the Kestrel across South Australia.
