Ash Spec Ireland Ltd
Doctoral Candidate / PhD position at Ashland Specialties Ireland Limited
Are you the kind of person that is always thinking, sketching, seeking, and adjusting? Who needs to understand how things work and then figure out how they can work better? Are you a passionate, tenacious, solver who loves to work with others who share your drive? Are you positive, constructive, and ingenious?
Are you always solving?
Then we'd like to meet you and bet you'd like to meet us.
About the role
The position is part of the European Doctoral Network "SHIELD" (Strategies for Healing Implant-associated infections and Enhancing Longevity in Devices). SHIELD offers an exciting opportunity for early-career researchers to contribute to transforming the management of infections associated with medical implants. Focused on addressing the challenges posed by implant-associated infections (IAIs), SHIELD aims to deepen our understanding of IAI mechanisms and develop innovative antibacterial biomaterials to improve patient outcomes.
Objectives
This PhD project will focus on developing advanced surface patterning and coatings and evaluate preclinically their potential as protective barriers to inhibit bacterial adhesion and biofilm formation while maintaining biocompatibility and promoting tissue regeneration. The doctoral candidate will develop bioresorbable polymers with controlled degradability, enhanced antimicrobial activity, and tunable mechanical properties suitable for clinical application. These approaches will be ultimately evaluated in a very close collaboration with the Royal College of Surgeons in Ireland (RCSI) where the PhD candidate will be registered and co-supervised by Associate Professor Oran Kennedy from RCSI .
Research activities include
* Material Synthesis: Develop novel bioresorbable polymers incorporating non-toxic antimicrobial agents.
* Surface Functionalisation: Apply chemical techniques to enhance surface biocompatibility and prevent bacterial adhesion
* Characterisation:
* Assess physical and mechanical properties
* Evaluate antimicrobial efficacy against clinically relevant pathogens
* Conduct in vitro biocompatibility
* Biological Testing:
* Perform in vitro and in vivo studies to assess tissue response and biofilm resistance
* Investigate biofilm formation and intracellular survival
Training and mobility
The PhD candidate will participate in research secondments at SHIELD partner institutions:
* University College Dublin, Ireland
* Royal College of Surgeons in Ireland, Ireland
* Hospices Civils de Lyon, Lyon, France
* Take part in specialized training workshops and international congress
Skills, Qualifications, Specific Requirements
* Applicants must hold a Bachelor's degree or equivalent in Chemistry, Engineering or similar providing access to PhD programs and should have experience with experimental research.
* Applicants must have excellent proficiency in written and spoken English.
* Strong motivation and ability to collaborate in an interdisciplinary and international team
Application/Eligibility criteria
* PhD researchers who have successfully defended their doctoral thesis but who have not yet formally been awarded the doctoral degree are not eligible.
* Career stage: applicants must be within the first 4 years (full-time equivalent) of their research careers at the date of recruitment (measured from the degree obtention date) to be eligible
* International mobility: candidates must not have resided or conducted their main activity (work, studies…) in Ireland for more than 12 months within the 3 years immediately preceding their recruitment.
* Interested candidates should send an application containing the following documents, in English:
* Motivation Letter (describing research career goals, skills, and experience)
* A complete Curriculum Vitae with references to past research and training experiences
* Deadline: 31st October 2025
Further information
* Benefits: The appointment will be on a temporary basis for a maximum period of 36 months (PhD student, regular full-time employment contract), with an attractive salary plus allowances package according to the Marie Skłodowska-Curie / Innovative Training Networks rules
