PATH is a global nonprofit dedicated to achieving health equity. With more than 40 years of experience forging multisector partnerships and with expertise in science, economics, technology, advocacy, and dozens of other specialties, PATH develops and scales up innovative solutions to the world’s most pressing heath challenges.

PATH’s AI Initiative is pioneering the use of generative AI and other advanced digital technologies to accelerate biomedical discovery, strengthen regulatory systems, and enhance the safety and scalability of digital healthcare.

The Research Fellow will be a key member of the AI4

Science team, working under the supervision of the Deputy Director (AI4

Science) and the Chief AI Officer to deliver research across the team’s portfolio. You will have a particular focus on a flagship programme funded by FCDO that aims to accelerate global health research through AI Co‑Scientist tools. This programme includes developing a benchmarking framework for evaluating AI Co‑Scientist tools, running real‑world demonstration projects in areas such as mental health therapeutics, antimicrobial resistance, and malaria vector control, and establishing a secretariat to support partners in adopting AI‑for‑science workflows.

This is a hands‑on role ideal for an applied researcher (post‑PhD or equivalent) who enjoys experimentation, interdisciplinary collaboration, and translating emerging AI capabilities into real scientific workflows. You will own specific work streams within the AI4

Science portfolio, from experimental design through execution and publication, while collaborating closely with senior technical leadership and external partners. You will develop and test AI‑assisted scientific workflows, and contribute to the growing evidence base for how AI can accelerate biomedical discovery. You will also contribute to the wider AI4

Science portfolio, including work on vaccine development and other projects as they arise. This role does not necessarily require developing new foundation models, but does require strong fluency in applying, evaluating, and orchestrating modern AI systems (including LLMs and agentic workflows) specifically for scientific research.

If you’re a researcher who wants to work at the cutting edge of AI and biomedical science, with the opportunity to see your work translate into real‑world impact for underserved communities, this could be the role for you.

• Contribute to and, where appropriate, lead research activities across multiple projects within the AI4
  
  Science portfolio, including:
• Designing, building, and iterating benchmark evaluations for AI Co‑Scientist tools, covering tasks such as knowledge retrieval, reasoning, robustness, rediscovery, and adversarial testing.
• Supporting the delivery of real‑world demonstration projects (e.g., mental health therapeutics, AMR susceptibility testing, malaria vector control), including facilitating expert workshops, running AI‑assisted hypothesis generation exercises, and coordinating small‑scale lab validation studies with partners.
• Contributing to a landscape mapping exercise to catalogue and functionally test available AI Co‑Scientist tools.
• Practical coordination support to help FCDO partners articulate research questions, select appropriate AI tools, and execute guided research sprints.
• Contributing to other AI4
  
  Science projects, such as work on identifying novel correlates of protection to accelerate vaccine development using agentic AI workflows.
• Apply and develop quantitative research methods (e.g., experimental study design, statistical analysis) and technical AI methods (e.g., prompt engineering, agent architecture design, evaluation method development) both independently and in collaboration with partners.
• Contribute to the technical writing of study protocols, donor reports, peer‑reviewed publications, and the publicly accessible AI4
  
  Science Playbook.
• Support the development and maintenance of collaborations with academic, industry, and Global South research partners.

• Support the Deputy Director in ensuring the timely delivery of…
