Postdoc Positions (Research Fellowship )

Job Details

Mitigating the effects of stress in early-life stages of fish is a critical challenge for the aquaculture industry and biomedical research using zebrafish as an experimental model. In this regard, the FORTIFISH project aims to develop fortified functional foods that promote the well-being and health of marine fish and zebrafish. This innovative project focuses on formulating foods fortified with bioactive peptides capable of reducing the impact of stress factors and improving production efficiency from the early stages of fish development. In i3S, the FORTIFISH functional solution will be tested aiming to optimize adult zebrafish welfare, species used in the biomedical industry. The contracted postdoc will be responsible for communicating with the animal facility to monitor the animal care and keep the best husbandry conditions for the zebrafish. The post-doc will be involved in the induction of stress protocols and in the execution of behavioural testing and subsequent video analysis. The postdoc will also quantify biomarkers using molecular biology techniques, such as ELISA and proteomics.

Requirements

Mandatory: 

- Candidates must hold a PhD degree in Veterinary Sciences, Aquatic Environment Sciences, Animal Science, Biology or related areas for less than three years. 

To have license to work with laboratory animals;

Preferencial: Solid experience and practical knowledge on the following aspects:

- The care, housing, handling, and maintenance of laboratory fish, especially zebrafish;

- Behavioural testing in fish, particularly in stress;

- Experience in molecular biology techniques, namely ELISA kits and proteomics.

The applicant should have interest in animal welfare and to be capable of identifying stress in zebrafish.

The Doctorate beneficiary of this type of fellowship cannot exceed, with the conclusion of the fellowship contract, an accumulated period of three years under this type of scholarship, continuous or not continuously calculated. The calculation of the three years period considers also all the host entities to which the Doctorate has been linked to by a postdoctoral fellowship. 

PhD holders of this type of fellowship must also have carried out the research work that led to the attribution of the PhD degree in a host institution other than i3S.

Legislation and other applicable regulations: Research Fellowship Holder Statute enacted by Law no. 40/2004 of August 18th, as amended; i3S Research Grants Regulation.

Place: The research activities will be hosted at i3S, under the scientific coordination of Prof. Anna Olsson.

Length time: The duration of the fellowship is 6 months, eventually reneawble. The expected starting date is 16th of January of 2026, upon availability of the financed funds.
