Lab Leaders

Professor Michael Gardner

I obtained my degree at QUT in Brisbane, and worked on a highly polymorphic intertidal snail during my honours, investigating the relationship of shell morph to background. I then worked with Dr Bob Ward (CSIRO Marine Labs) for 2 1/2 years in Hobart where I looked at population genetic structure in school and gummy sharks.  I came to Flinders University to study a PhD in a genetic investigation of sociality in a group living lizard with Prof. Mike Bull. I spent time in England for 3 1/2 years studying co-evolution between parasitic hoverflies and their host ants. I returned to Adelaide for a two year postdoc with Flinders Biological Sciences where I linked Flinders and the SARFMEE. I have been in my current role at Flinders since halfway through 2008. I have a joint position with the South Australian Museum. For more information please visit my Flinders University or Google Scholar profile or to contact, click here.



Dr. Amy Slender (Research Associate)

Amy completed her undergraduate and Honours at the University of Western Sydney. Her career in research began with a project on marsupial immunology which was followed by an honours project about understanding the effects of stress on the immune system of the Koala. She then worked in medical research where she gained experience in a number of labs working on projects such as indigenous health at the Menzies School of Health Research in Darwin, vaccine development and clinical testing at Oxford University in the UK and disorders associated with Down’s Syndrome at the London institute, National Institute for Medical Research (now amalgamated to the Crick Institute). She recently completed a PhD studying population genetics of the Thick-billed Grasswren. This project tested hypotheses regarding species evolution in this arid zone bird and also gathered data that can be used to make informed decisions about the conservation of this threatened species. Amy is currently employed to investigate the influence of two parapatric tick species on the evolution of the sleepy lizard. Please see Amy’s Flinders University and LinkedIn profile for more information.

Gerrut received a National Certificate (N.Cert.) in Production Management from Technikon Witwatersrand (1997).  He also received a N.Cert.: Nature Conservation (2003), a National Diploma: Nature Conservation (2010), and Master of Science: Nature Conservation (2015) from the University of South Africa (UNISA).  From 2000 to 2016, he was actively involved in field research on herpetofauna (primarily lizards) in Taiwan (publications of his research can be found on his ResearchGate profile), and has been an Associate Researcher of the Applied Behavioural Ecology and Ecosystem Research Unit (ABEERU), Department of Environmental Sciences, UNISA, since 2004.  He has broad research interests in the natural history of lizards and snakes, reptiles as invasive species, and parasites of reptiles. Gerrut started his PhD studies in 2017 and his research will be examining the parasites of the sleepy lizard (Tiliqua rugosa) across an ecological gradient. His project is supervised by Prof Mike Gardner, A/Prof Kirstin Ross and Dr Bob Sharrad.

Dr. Lynea Witczak Oldfather (Fulbright Postdoctoral Scholar)

Lynea earned her B.S. in Biology from Davidson College where she studied reptile and amphibian population ecology. After graduating, she worked at Florida State University studying upland chorus frog (Pseudacris feriarum) mate choice behavior. Her interest in better understanding mechanisms underlying animal sociality led to a shift from studying herpetofauna to working with primates at Emory University’s Yerkes National Primate Research Center. She then went on to earn her M.A. and Ph.D. in Biological Psychology from the University of California, Davis. Her graduate work investigated the role of father-daughter relationships in mediating behavioral, physiological, and neural mechanisms underlying social bonds in monogamous coppery titi monkeys (Plecturocebus cupreus). To determine whether similar mechanisms promote pair bonding across taxa, Lynea has returned to studying reptiles as a Fulbright Postdoctoral Scholar at Flinders University. She is currently investigating the neurobiology of pair bonding in socially monogamous sleepy lizards (Tiliqua rugosa) by validating methods for measuring and manipulating oxytocin and dopamine. This research aims to provide insight into potential shared mechanisms underlying sociality across vertebrate taxa. Please see Lynea’s ResearchGate, website, and Twitter for more information.

Robert begins his PhD in 2018 continuing to work on the sleepy lizards with A/Prof Mike Gardner and A/Prof Mike Schwarz. His PhD focuses on creating an antibody test for the first nidovirus ever reported in lizards, as well as gene expression analysis between infected vs non-infected lizards.


Jack Bilby (2021)

Jack is a BSc Animal Behaviour graduate currently working on his Honours degree under the supervision of A/Prof Mike Gardner and Dr Katherine Moseby. Unlike most of the LEGS Lab, Jack is looking at something with fur instead of scales, the western quoll! The Flinders Ranges is home to South Australia’s only quoll population, following the reintroduction of western quolls (Dasyurus geoffroii) to the region.  As part of the ongoing monitoring of the reintroduced population, Jack is investigating the dispersal patterns of juvenile quolls and whether these individuals may be increasing their risk of predation by feral cats and foxes.

James Dorey (February 2018 – 2021)

James Dorey is driven by a love of nature that was first instilled in him when growing up in the Northern Rivers, amongst the rainforest regenerated by his father. This provided James with an environment rich in plant and animal life to explore. These interests were carried into his science degree where he studied ecology and zoology at the University of Queensland. James’ honours project focused on how past climate cycles may have driven speciation of highland endemic bees in Fiji. In addition to his studies, James is an avid macro photographer who loves to share his passion for nature with a broad audience in a number of publications and competitions. To see some of what James has seen and imaged feel free to have a browse here.

Olivia Davies (March 2016 – 2021Olivia_photo)

Olivia started her honours here looking at nest-mate recognition and historical demography in a facultatively social native bee Amphylaeus morosus. She discovered that this species has no mitochondrial diversity within its whole population except for two different mitochondrial types that persist in every bee. This widespread mitochondrial heteroplasmy became the focus of her research, and she is now continuing with us, co-supervised by A/Prof Mark Stevens (SA Museum), doing her PhD on the same topic. She is exploring the connection between heteroplasmy and the intracellular parasite Wolbachia, and its prevalence in other bee species in the family. More information on Olivia’s research can be found on her ResearchGate profile.

Dr. Jessica Clayton (Research Assistant)

Jess completed a Bachelor of Science (Ecology and Biodiversity) at Queensland University of Technology in 2009, and continued there to complete her Honours (2010). She studied habitat use in an intertidal and sub tidal zone by a fish assemblage in SE Queensland, testing the effectiveness of BRUV (baited remote underwater video) as a sampling method. She recently completed her PhD, supervised by A/Prof Mike Gardner and Prof. Mark Hutchinson (previously supervised by the late Prof. Mike Bull). She investigated how pygmy bluetongue lizards and burrowing spiders co-exist in native grasslands, utilising the same resources as refuges and identified niche partitioning as a mechanism. Her project also identified the impact of sheep grazing on spider and lizard burrow use, burrow construction and burrow persistence.  To see Jess’s publications please visit her ResearchGate profile.



Sarah Barker (2020)

Sarah is interested in the role social evolution plays in the ecology of species. She completed her double Bachelor of Science (Animal Behaviour) (Biodiversity and Conservation) at Flinders in 2020. In her final year she was involved in some research in the bee lab with A/Prof Mike Schwarz looking at trophallaxis in native bees and the thermal tolerances of Fijian bees. After completing her undergraduate degree, her started her honours looking at the social dynamics of gidgee skinks (Egernia stokesii) under the supervision of A/Prof Mike Gardner and A/Prof Greg Johnston. Her findings have suggested that gidgee skink aggregation dynamics vary in response to environmental differences.

Ben Parslow (2016 – 2020Ben)

Ben’s current research explores the systematics and evolutionary relationships between the predator inquiline wasp genus Gasteruption and its native bee hosts. Ben has developed a strong fascination for the taxonomy and biology of these unusual wasps during his honours work and is now applying his experience with taxonomy and phylogenetics to answer questions related to host specialisation and co-phylogenetic relationships. He is supervised by A/Prof Mike Schwarz, A/Prof Mike Gardner and  A/Prof Mark Stevens.

Bonnie Derne bonnie( February 2015 – 2021)

Bonnie has harboured a passion for parasites since contracting head lice (Pediculus humanus capitis) as a young child. After studying Zoology and Biochemistry at the Unversity of  WA and completing honours at University of QLD on disease regulation by biodiverse ecosystems, Bonnie was lured to South Australia by the call of the pygmy bluetongue (PBT) lizard (Tiliqua adelaidensis). Her project, supervised by  A/Prof. Mike Gardner,  Prof. Mark Hutchinson, and Prof. Phil Weinstein (previously supervised by the late Prof Mike Bull), is part of a risk assessment of an experimental translocation of this endangered and highly endemic skink species. It aims to characterise the parasite biota of the PBT and comment on the risk of transmission of allopatric parasites to naïve hosts. Please see Bonnie’s GoogleScholar profile for her past publications.
