Ceu Figueiredo
Group leader

Ceu Figueiredo, PhD, is Coordinator of the Microbes & Cancer Group at i3S and Associate Professor at the Department of Pathology, Faculty of Medicine of the University of Porto. Her research focuses on the microbial and host determinants of gastric carcinogenesis, with long-standing contributions to the study of Helicobacter pylori infection, including the clinical relevance of bacterial virulence factors, host genetic susceptibility, and infection-induced epithelial responses.

Over the last decade, her work has expanded from H. pylori-centered gastric cancer pathogenesis to the broader role of the gastric microbiome in cancer development and patient stratification. Her group combines clinical cohorts, gastric tissue specimens, experimental models, next-generation sequencing and microbial/metabolite profiling to identify microbiome-associated signatures, microbial metabolites and host-microbe interactions relevant to gastric cancer risk, diagnosis and progression.

She has coordinated and participated in national and international competitive projects funded by the Foundation for Science and Technology (FCT), Agency for Innovation, Ministry of Health, European Commission (FP6, H2020, and Horizon Europe), Worldwide Cancer Research and other agencies. As of June 2026, she has published over 140 peer-reviewed papers and 10 book chapters, holds two international patents, and has an h-index of 51.
