Oferta compartida por Nuria


Three PhD projects currently open for applications at ATU Galway.

These two positions arise for the recruitment of suitably qualified and strongly motivated graduate to undertake a PhD in ATU as part of a 5-year large scale interdisciplinary research project: “GIDAS - Gill Disease of Atlantic Salmon”. 

Aquaculture provides an important food source worldwide and increasingly contributes to the global economy, as well as national research priorities. Complex gill disease (CGD) is a major challenge in finfish aquaculture, leading to substantial reductions in production annually. Treatment using freshwater baths only provides a temporary solution and a better understanding of CGD is needed. CGD involves a range of organisms including parasites, bacteria and viruses, and can be influenced by production practices, such as net washing. Due to this complexity, CGD remains a major obstacle to successful aquaculture production and requires further research. Furthermore, gill-associated diseases in Atlantic salmon (Salmo salar) lead to considerable annual losses the Irish aquaculture sector. The overall aim of the GIDAS project is to increase knowledge of CGD, including one of the leading pathogens involved, Neoparamoeba perurans, which itself leads to amoebic gill disease but is also a key player in CGD. Key objectives include: reviewing the current epidemiology of CGD in Ireland; testing a CGD model; identifying potential biomarkers and developing preventative and curative measures to minimise disease occurrence. Led by ATU, the project’s consortium includes University College Dublin and a diverse team of collaborators from academia and industry to support the project’s main aim and objectives.

 An exciting opportunity has arisen for a suitably qualified and strongly motivated graduate to undertake a PhD as part of a collaboration between the Marine and Freshwater Research Centre (MFRC) at ATU’s Galway City Campus, BIM, the Marine Institute. Northeast Atlantic (NEA) mackerel (Scomber scombrus) is Ireland’s most valuable commercial fish species, with €73m worth of fish landed by Irish vessels in 2021 and exports valued at €109m in 2021. In recent years Irish pelagic processors have noted an increase in the occurrence of ‘jelly flesh’, most likely due to infection with the myxosporean parasite Kudoa sp. (Kudoidae). Increasing infection rates in more northern waters may be linked to a change in the distribution of the mackerel stock, changes in stock size or in size at age (Giulietti et al. 2022, Højgaard et al. 2022). Although not harmful to humans, heavy infection with the Kudoa sp. parasite can destroy the fillet and renders it commercially unusable. A PCR test has been developed that detects Kudoa sp. infection, even in fish without symptoms (Funk et al. 2007); this may have wider applications for the seafood processing sector in the future. The aim of this PhD research programme is to characterise Kudoa sp. infection in the Irish mackerel fishery using molecular and histological techniques, to identify biological and environmental factors associated with infection and to develop tools for mitigating the impacts on commercial fishing and processing operations.

research fellow Dr Ben Longdon, at the University of Exeter, Penryn
campus.

This full time post is available on a two year fixed term
contract, with the possibility of extension. Apply here
https://jobs.exeter.ac.uk/hrpr_webrecruitment/wrd/run/ETREC107GF.open?VACANCY_ID%3d472746SGEX%1BUSESSION=F734DF9523454CFE9CAE09B647684C58&WVID=3817591jNg&LANG=USA

About the role

Host-parasite interactions offer fascinating opportunities to study
coevolution, local adaptation and rapid evolutionary change. Our work
uses a unique experimental system of up to 50 species of Drosophila
and naturally occurring RNA viruses to ask fundamental questions about
pathogen host shifts ¡V where a pathogen jumps from one host species to
another. Host shifts are a major source of emerging infectious diseases,
with HIV, Ebola virus and SARS coronavirus having all jumped into humans
from other host species. By taking a comparative approach, with a strong
set of hypotheses from ecological and evolutionary theory, we can provide
insights into the factors underlying host shifts that will be generally
applicable to any group of hosts or viruses.

Understanding pathogen host shifts is critical, especially in light of
environmental change. Our model system has provided key insights into host
shifts, namely the importance of genetic similarity between hosts. Based
on work in Drosophila melanogaster, we know the interactions between host
antiviral immunity and the ability of the virus to supress this immune
response, can play a role in explaining differences in susceptibility. The
initial aim of the postdoc is to examine why viruses can infect some
hosts and not others by looking at how the viral suppressor of immunity
functions in different host species, and how this influences patterns of
susceptibility across the host phylogeny, but there are many opportunities
to develop new projects to explore the ecology and evolution of pathogen
host shifts.

Applicants will possess a relevant PhD or equivalent
qualification/experience in a related field of study.

The successful applicant will be responsible for leading experimental
work, data collection and analysis, working closely with the PI and
collaborators. The post will be based at the University of Exeter in
the internationally excellent Centre for Conservation and Ecology

https://www.exeter.ac.uk/cornwall/research/facilitiesandcentres/cec/. The
centre has a huge number of researchers working in ecology and evolution,
including a large group of researchers working on host-parasite
interactions (including Prof Angus Buckling, Prof Camille Bonneaud,
Prof Edze Westra, Prof Robbie McDonald, Dr Alex Hayward and Dr Stineke
Van Houte) and provides an exciting and stimulating research environment.

ground squirrels are fascinating animals that hibernate for 7 to 9 months
each year without eating or drinking, and regulate their body temperature
to -2.9°C, the lowest body temperature of any mammal. Despite months of
disuse and fasting, arctic ground squirrels lose little lean mass during
hibernation. We seek a postdoctoral scientist to lead investigations
combining multi-omics, stable isotope tracer, and culturing approaches to
examine the potential contribution of the gut microbiota to lean-mass loss
resistance via the production and provision of essential amino acids. The
postdoc will join an active and vibrant lab studying host-associated
microbiotas that includes technicians, graduate and undergraduate
students, with the opportunity to engage in student mentorship.

Faculty in Biological Sciences at UAA are engaged in research from
Arctic ecology to molecular biology, and ecosystem science to One

Fascinante tema para hacer un doctorado! Y en Nueva Zelanda!

PhD Project Opportunity

Parasitic Puppeteers - How do They Pull the Strings?
We are currently seeking at least one, but potentially several PhD students with interests in genetics, evolution, parasitology and neuroscience to investigate the molecular mechanisms through which
parasitic worms alter the behaviour of their insect hosts.

Project Description
Parasites can have profound effects on the animal hosts they invade,
manipulating host biology with exquisite precision to enhance host-to-host
transmission. One of the most extraordinary of these host manipulations
is the water-seeking behaviour that some nematodes and hairworms induce
in their hosts so that the worms might exit the host and reproduce. The
process is the stuff of science fiction; the worm hijacks the host’s
central nervous system forcing it to seek water. Once water is found the
adult worm, often many times the size of the host, emerges, sacrificing
the host. This amazing alteration in behaviour is induced by parasitic
worms spanning two phyla (Nematoda and Nematomorpha) and is observed
in a variety of arthropod hosts, notably crickets, weta, earwigs,
and sandhoppers, leading us to hypothesise that a common and conserved
mechanism is being utilised by the parasites to induce this behaviour in
their hosts. Here we propose to couple field and laboratory studies of
two phylogenetically distinct hosts and their parasites, with powerful
genomic and bioinformatic comparisons to elucidate the trigger and
genetic cascade through which these parasitic puppeteers elicit this
highly conserved, yet astonishing behavioural response.

The project emerges from a new Marsden Grant headed by Professor Neil
Gemmell (Anatomy) in collaboration with Professor Robert Poulin (Zoology)
and will be based in the Gemmell laboratory at the University of Otago.

The Ideal Candidate
The ideal candidate will possess experience in molecular
genetics/genomics, evolutionary biology and bioinformatics. Knowledge
of NGS approaches and analyses us desirable, while past work in
comparative genomics and an interest in parasitology and neurobiology
may be helpful. They candidate will be motivated and organized, with a
demonstrated capacity to master the broad skill set necessary for the
successful completion of a research project. They will be collegial and
able to work alongside a wide variety of people. In addition they will
have a strong commitment to academic and research excellence. Minimum
qualifications: B.Sc. (Hons) and/or M.Sc. in Genetics, Genomics, Molecular
Biology or equivalent with an A average or better.

Scholarship Funding: Financial support is expected to be
available for a high achieving student with an A average or
better via a University of Otago or Departmental scholarship see
http://www.otago.ac.nz/study/scholarships/).

Eligibility: The University of Otago and Departmental
scholarships are open to all nationalities. However,
overseas candidates for whom English is not a first language
must satisfy the English Language Requirements of the University
