Programme Aims & Structure

The PhD in Global Health (formerly INDIGO) programme aims to provide promising early career researchers with a world-class experience and scholarship. A four-year, full-time programme with a flexible structure, the PhD Global Health aims to produce leaders in global health research, policy, and practice. Typical for our doctoral candidates is to spend a considerable portion of their doctoral degree conducting research as part of ongoing global health and global mental health projects, in collaboration with one of our many national and international partners. Students who successfully complete their PhD will receive either a PhD Psychology or PhD Public Health and Primary Care, dependent on their supervisor.

The following outlines the major milestones of the PhD process, the timing of which may vary depending on the individual candidate and their respective research requirements:

In addition to their own research obligations, doctoral researchers are expected to attend and participate in the TCGH's weekly research seminars, held every Tuesday during lunch time.

By the end of their doctoral training, students gain first-hand knowledge and experience of conducting practical research in one or more of the following principal research areas: (1) Global Mental Health; (2) Health Systems Strengthening; (3) Human Resources for Health, and (4) Equitable Access to Inclusive Health.

By working closely with their supervisors, mentor panels, TCGH partners, and fellow doctoral researchers, our PhD students emerge from the programme confident in their ability to independently design and conduct global health research. Students also have the opportunity to avail of career development opportunities by getting involved with the following TCGH activities:

    • Research grant writing and submission to funding bodies
    • Academic writing and publication
    • Critical thinking and conceptual framing of international development work
    • Conducting research in resource-constrained settings and/or with vulnerable populations
    • Post-graduate teaching and co-supervision through engagement with BA or MSc programmes


We are currently reviewing applications for doctoral theses that are related to the following research topics:

  • Global Health (Supervisor: Dr Felicity Daly) - Supervisor for PhD Public Health and Primary Care
  • Child and adolescent mental health and wellbeing; resilience; randomised controlled trials; parent-child relations; refugee youth and families; climate change (Supervisor: Dr Kristin Hadfield) - Supervisor for PhD Psychology
  • Global mental health; social determinants of mental health; sexual reproductive health and rights, LGBTQIA+ health and mental health, gender-based violence, (Supervisor Dr Meg Ryan) - Supervisor for PhDs in Psychology or Public Health and Primary Care
  • Global mental health; global health and international development; psychological responses to trauma; human resources for health and task-sharing models of health service delivery; health system strengthening, (Supervisor: Dr Frédérique Vallières) - Supervisor for PhD Psychology


Please note that, unless otherwise indicated, there is currently no funding available for PhD posts, so candidates must be self-funded or have secured their own bursaries. That said, the opportunity to apply for a Trinity Postgraduate Research Award is available to those who have secured a place on the programme. When reaching out to potential supervisors, please provide information on whether you have secured funding for your tuition fees and stipend and, if not, what funding you would intend to apply for in order to support yourself while conducting the PhD. Note also that proposed PhD projects should be consistent with the funding available; if you have not already secured funding to support conducting the research itself, your research proposal should be for a research project which could be conducted at no or relatively low cost.

Admission to the PhD Global Health programme at Trinity College Dublin is highly competitive. Applicants must possess a strong academic record, international research experience, and a keen interest in global health research. Admission to the programme takes place in three stages.

Do I get to select my supervisor, or will I be assigned one?
Potential students are encouraged to apply todo a PhD in the Trinity Centre for Global Health having identified a member of staff within Trinity College Dublin that has agreed to supervise their work. Supervisors should have expertise in the area of research of interest to the candidate, as well as the availability to take on additional PhD students. You will not be assigned a supervisor.

Do I have to teach or supervise other students while enrolled in the PhD Global Health?
There are a number of opportunities for doctoral researchers to both teach and co-supervise students enrolled in the BA Psychology, MSc Global Health, or MSc Glbal Mental Health programmes. This allows researchers to gain valuable teaching and supervision skills as part of their doctoral training. Supervision of master's theses is generally shared with a full-time academic staff member.

How many courses must I take for credit in order to fulfil the requirements of a PhD?
The number of compulsory modules varies across Schools. Therefore, the number of ECTS credits required to fulfil the requirements of a PhD is entirely dependent on the School in which you are enrolled. Should you be invited to submit a formal application, you would enrol in the School where your primary supervisor is based. Attending and presenting at the weekly TCGH Seminars each term is mandatory for all PhD candidates in the Trinity Centre for Global Health.

What are the deadlines for submitting an application to the PhD in the Trinity Centre for Global Health?
Trinity has two enrolment periods: September and March intakes. If candidates wish to be considered for the March intake, it is strongly advised that they submit their application by December 1st. For a September start, it is strongly advised that candidates submit their application by June 1st.

Am I permitted to have a co-supervisor from another institution?
A second, or even third, co-supervisor may be beneficial. Typically, co-supervisors are located within organisations in the country where the student’s research is taking place. In 2014, TCD introduced an internal PhD advisory system whereby all PhD students are assigned two advisors in addition to their appointed supervisor. These mentors will be chosen by you and your supervisor and approved by the Director of Postgraduate Teaching and Learning. You will be expected to arrange a meeting with your supervisor and your two mentors at least once a year to review your progress and the annual report on your work, which you will be expected to write ahead of this meeting. Students are responsible for preparing an annual report based on the research they have been undertaking.

Will I have the opportunity to study or work in other institutions outside of Trinity College Dublin during the course of my PhD?
Many of our PhD students spend time with one of our numerous international collaborating partners. This includes, but is not limited to, spending time in partner academic institutions in both low and middle-income countries, UN agencies, the private sector, and non-governmental organisations. As many of our students’ research takes places in resource-poor contexts, it follows that many of our students spend a considerable amount of their time outside of the Trinity Centre for Global Health.

What funding options are available to PhD students?
Unfortunately, there is very little funding available for PhD students. For current openings for funded PhD positions as well as relevant PhD funding bodies please see Fees and Bursaries.

What if I do not have a background in Global Health, can I still apply?
As an interdisciplinary Centre, applications are welcome from individuals with diverse educational and academic backgrounds as long as the research conducted as part of their PhD is clearly related to the area of Global Health. Preference is given to applicants whose research falls under one of the Centre’s principal research themes. Individuals should also clearly demonstrate a deep understanding of the principles and theories of Global Health research.
