About the job
Join the Dublin Dental University Hospital as a Postdoctoral Research Fellow in Oral Microbiome!
The School of Dental Science at Trinity College Dublin and the Dublin Dental University Hospital (DDUH) is excited to announce an opening for a Postdoctoral Research Fellow / Problem-Based Learning Tutor within the Division of Oral Biosciences. This is a full-time position under a fixed-term contract lasting three years.
This role is crucial for advancing research on the oral microbiome and also includes an educational component, as the successful candidate will facilitate Problem-Based Learning tutorials for first-year Dental Science undergraduates (approximately 120 hours per year).
The successful applicant will primarily report to the Head of the Division of Oral Biosciences and will work closely with Prof. Gary Moran on daily tasks. Management oversight will be provided by the Executive team of DDUH, including the CEO, Dean, and Clinical Director.
Located in the heart of the Trinity College Dublin campus at Lincoln Place, the role involves investigating the role of the oral microbiome in oral malignancy development through metagenomics and culturomic techniques. Additionally, the fellow will coordinate various ongoing microbiome research initiatives in the laboratory.
