Professor Robert Poulin
Since arriving here from Canada in 1992, I have established a research programme in parasite ecology and evolution that focuses on broad questions and not on any particular taxa. Currently, our research has three main branches, reflecting my main long-term interests. First, we investigate the forces shaping the evolution of parasites, in particular the evolution of life history traits such as body size and fecundity, host specificity, the ability to manipulate host behaviour, and the complexity of the transmission pathways. Second, we are studying the role of parasites in freshwater and coastal marine ecosystems, i.e. how they affect community diversity and productivity and food web stability, and how parasitism may interact with climate change to influence the properties of ecosystems. Third, I have long been exploring large-scale patterns of parasite biodiversity and biogeography, in the hope of better understanding the processes behind the diversification and distribution of parasites and diseases.
Dr Eddy Dowle (Research Fellow)
Originally from Otago, I completed my PhD at Massey University (New Zealand) in 2014. Following my PhD, I took up a short-term position at the Cawthron Institute in Nelson before moving to the USA to work at the University of Colorado. My previous work has focused on using genomic techniques to explore genetic diversity and environmental adaptation in several invertebrate species. But I have broad research interests in evolution, genomics and development. My current work at Otago (in collaboration with Prof. Neil Gemmell, Anatomy Dept.) focuses on using genomic techniques (transcriptomics and bi-sulphite sequencing) to understand how nematomorph and nematode parasites manipulate their normally terrestrial arthropod hosts to seek water.

Dr Amandine Sabadel (Research Fellow)
Hi everyone, my name is Amandine, and I am originally from France, where I completed a BSc in chemistry and a MSc in nuclear chemistry at the Université Montpellier II. I then moved to Vancouver, Canada, and worked at the NRC/CNRC on the development of proton-exchange membrane fuel cells. After a year there, I relocated to the other side of the world to complete a PhD in marine isotope biogeochemistry from the University of Otago, Dunedin, in 2015. Fast-forward a few years of postdoctoral experience, I am now a Research Fellow at the University of Otago and an isotope consultant at the National Institute for Water and Atmospheric research (NIWA), Wellington. It is hard to fit my research interests into one category as I work across a lot of different fields of research, but overall, I consider myself an isotope bio-geo-eco-chemist! I am joining the Parasite Lab as I was awarded a Marsden Fast-Start grant to investigate the trophic interactions between a parasite and its host(s), using compound-specific stable isotope analyses.
Dr Priscila Salloum (Postdoctoral Research Fellow)
Born and raised in Brazil, I completed a BSc and teaching degree in Biological Sciences, at the State University of Campinas (UNICAMP), where I also did a MSc in Molecular Biology and Evolution. I moved to the University of Auckland to undertake a PhD, unravelling population genomics of brooding chitons that raft in kelp. My PhD showed me the power of genomics as a tool to understand diversity and evolution, and raised many questions that would require further genomic resources to be generated. This led me to a short postdoc sequencing a chiton genome and transcriptome, also at the University of Auckland. My main research interest is understanding the diversification of phenotypes and the role of different factors (genetics, environment, and microbiomes!) on evolution. Now at the University of Otago, I will be using the genomics toolbox to better understand the role of microbiomes in manipulating the phenotype of parasites and their hosts, as a window to understand phenotype diversification driven by the composition and abundance of microbial communities.

Dr Jerusha Bennett (Postdoctoral Research Fellow)
Kia Ora, I grew up in Geraldine, NZ, and received my BSc here at the University of Otago. I then completed a MSc in Ecology, again at Otago, investigating the trophic transmission routes of cestode parasites of New Zealand skates. After this, along with Bronwen Presswell, I investigated parasite biodiversity in New Zealand birds and fishes, producing new species descriptions and using genetic markers to resolve life cycles. This research was conducted in partnership with Otago Museum, and served to assemble New Zealand's largest parasite collection. This work developed into a PhD that allowed me to map parasite transmission patterns on the entire food web of the Otago coastal ecosystem, using genetic tools to match larval and adult helminth stages across all major food chains. At present, in partnership with the Cawthron Institute and funded by a MBIE Endeavour grant, I continue my research on the parasites of New Zealand animals, with a focus on their potential as agents of emerging infectious diseases in aquatic organisms.
Daniela de Angeli Dutra (PhD student)
Hello, I'm a biologist from Brazil (and no, I do not know how to dance samba). I obtained a Masters degree in Ecology from the Federal University of Minas Gerais (UFMG). Throughout my studies, I conducted laboratory research in the Parasitology department at the Institute of Biological Sciences. During this period, I dedicated myself to the study of hemoparasites of the order Haemosporida infecting wild animals, investigating the interaction between hosts, parasites and the environment in which they live. These studies allowed me to acquire knowledge about the various ecological interactions between parasites and their vertebrate and invertebrate hosts, providing me with an interdisciplinary perspective between ecology, evolution and parasitology. Now, for my doctorate, I intend to evaluate the importance of bird migration for the transmission of avian haemosporidians, and for their local diversity and prevalence.
Xuhong Chai [Rose] (MSc student)
I am originally from China. I came to New Zealand for a working holiday in 2012 and in the end managed to live here. I worked for several years in a factory and then realised I really wanted a job where I could use my brain instead of just fast hands. Being a Zoologist was always my childhood dream, so I decided to go to study at the University of Otago in 2017. Fascinated by how parasites can manipulate host behaviour, I contacted Robert to volunteer in his lab to learn more about the topic. I have been volunteering in Robert's lab since 2018 and developed an interest in the ecology and evolution of parasites. I have just completed my Bachelor of Science degree with a Zoology major and Ecology minor in 2019. Now I'm starting my Master of Science degree focusing on deep-sea parasites. I hope to investigate the parasite communities of different species of rattail fish and also the co-evolutionary history of different species of trematodes with their rattail hosts.
Sila Viriyautsahakul (MSc student)
I am originally from Thailand. I came to New Zealand to study for my Bachelor in Science degree at the University of Otago, majoring in Zoology. After volunteering in the parasite lab during my undergraduate studies, I decided to pursue a MSc degree in parasitology. My thesis project will explore the effects of infection by brain-encysting trematodes (genus Cardiocephaloides) on the behaviour of New Zealand triplefins (Forsterygion spp.), which are small intertidal fishes serving as intermediate hosts for the trematode.
Jérémy Dubrulle (Honours student)
Hi There! I'm Jérémy, just another Islander! I grew up in Réunion Island, Indian Ocean (French department) and left to pursue my education in France (mainland) as well Australia at the Australian National University. I graduated in Biology/Life sciences in 2019. Shortly after, I went back home and worked in an infectious disease lab for a year and a half. This Research Assistant position gave me some knowledge of molecular microbiology techniques as well as full-genome sequencing techniques using the Oxford Nanopore technologies. I then moved to Dunedin in June 2022 and worked as an RA in the Microbiology Department under Dr. Jemma Geoghegan's supervision, until December 2022. I am now doing an Honours project with the Microbiology Department but associated with the parasite lab. My research investigates the geographical variation in the virome of a nematode parasite, Thaumamermis zealandica, infecting sandhoppers on beaches along the southeastern coast of New Zealand.
Dr Bronwen Presswell (Scientific Officer & Lab Manager)
I am from the UK where I gained a Masters in Advanced Methods in Taxonomy and Biodiversity at the Natural History Museum, London. For my PhD at Glasgow University and the NHM, I studied the morphological and molecular systematics of Indian caecilians at the intraspecific level. I currently investigate the identities and life cycles of parasitic helminths that are found in, and on, New Zealand wildlife, from invertebrates to fishes, elasmobranchs and birds. The parasitic worms of NZ wildlife have not been well studied, and I continue to find and describe new species all the time, and complete life cycles for species known only as larvae. A collaboration with the Dunedin Wildlife Hospital has allowed me access to their deceased birds, which have yielded hundreds of parasite specimens, forming probably the largest parasite collection in New Zealand, which has been submitted to the Otago Museum. Using molecular, histological, scanning electron microscope and other methods I hope to fill a few gaps in our knowledge of this parasite fauna.
