"The programmable microbiome: engineering diet and probiotics to enhance gut resilience” With Ophelia Venturelli, PhD
2026-01-20 16:30 - 17:30 | Marsico Hall 2004
Dr. Ophelia Venturelli is an Associate Professor of Biomedical Engineering at Duke University. The Venturelli lab aims to understand and engineer microbiomes and host-microbiome interactions for applications spanning human health, built environment and agriculture. Specifically, we combine high-throughput experiments, synthetic biology, computational modeling and multi-objective optimization to discover control knobs in the microbiome and design precision interventions that can steer these systems to desired states.

"When Cells Pause: Visualizing Quiescence in the Gut” With Martha S. Johnson, PhD
2026-02-10 16:30 - 17:30 | Marsico Hall 2004
Dr. Martha S. Johnson is a Postdoctoral Research Associate in the Department of Biochemistry and Biophysics at the University of North Carolina at Chapel Hill School of Medicine, working under the direction of Dr. Jean Cook and co-mentored by Dr. Scott Magness. Her work in the Cook Lab focuses on understanding how the cell cycle is regulated, with a particular emphasis on the molecular mechanisms governing cell cycle exit and quiescence. Using live-cell imaging and biosensor-based approaches, she integrates bioanalytical chemistry, quantitative imaging, and molecular and cell biology to study how epithelial cells dynamically balance proliferation and arrest to maintain tissue homeostasis.

"Adaptation of the beneficial commensal microbe Akkermansia muciniphila to gastrointestinal mucins and its effects on host physiology” With Raphael H. Valdivia
2026-02-24 16:30 - 17:30 | Marsico Hall 2004
Raphael H. Valdivia is the Nanaline Duke Professor of Molecular Genetics and Chair of the Department of Integrative Immunobiology at Duke University School of Medicine. His research focuses on understanding how pathogenic and beneficial microbes adapt to their environments and how they influence the physiology of their hosts. The work presented will focus on Akkermansia muciniphila, a mucophilic microbe currently being considered as a next-generation probiotic for various immune and metabolic disorders.

"Gut E. coli–Derived Metabolites Drive Macrophage–Fibroblast Crosstalk to Promote Intestinal Fibrosis in Crohn’s Disease” With Ju-Hyun Ahn, PhD
2026-03-17 16:30 - 17:30
Dr. Ahn is a postdoctoral fellow in the Arthur Lab in the Department of Microbiology and Immunology at the University of North Carolina at Chapel Hill. Her research investigates how intestinal microbes and their metabolites influence host signaling networks that drive chronic inflammatory diseases, including inflammatory bowel disease, fibrosis, and microbe-associated tumorigenesis. Her work focuses on microbial metabolite–driven macrophage activation, immune–stromal crosstalk, and fibroblast activation to identify molecular targets that may prevent or reverse chronic inflammation and its downstream pathologies.
