UPenn Digestive and Liver Center

The mission of the UPenn Digestive and Liver Center is to unite investigators with interests in digestive and liver disease in the exploration of creative experimental approaches, as well as to stimulate others to enter these areas of research. The scientific focus of the Center revolves around host-environmental interactions in digestive and liver disease research from bench to bedside. The Center is divided into three thematic areas: Intestinal Biology, Liver Biology, and the Microbiome. Center resources include five biomedical research cores to support research in both model systems and human subjects, a pilot & feasibility program, and various enrichment activities including a weekly seminar series, liver and intestinal stem cell clubs, and an annual retreat.

Announcements

Message from Our New Center Director, Ken Cadwell!

Dear Colleagues and Friends, 

I am honored to step into the role of Director of the UPenn Digestive and Liver Center and to have the opportunity to serve such an accomplished community. As I begin this new chapter, I first want to express my deep gratitude to Dr. Gary Wu for his exceptional leadership and dedication over the years. Gary’s contributions have been instrumental in shaping the Center’s success, and I am delighted that he has graciously agreed to continue serving as a co-Associate Director alongside Dr. Becky Wells. I am lucky to have their guidance as we build on the strong foundation they have established and navigate the challenges that may arise during this politically volatile period. 

This edition of our quarterly newsletter brings exciting updates, including the announcement of our pilot award winners. The selection process was highly competitive, with a remarkable number of outstanding applications. This is a testament to the innovative research happening across our community. Congratulations to the awardees; your work embodies the excellence we strive to foster. 

You may also notice that we’ve simplified our name to the UPenn Digestive and Liver Center, a change intended to make our identity clearer and easier to remember while staying true to our mission. 

In my new role, I am committed to supporting our excellent core services and promote community building through the many enrichment activities organized by the Center. I look forward to working with all of you to drive our Center’s continued growth and impact. 

Warm regards,  Ken

  • SupeRJump: Determining normal and leukemic differentiation fate through semi-supervised jump diffusion modeling Friday, July 17, 2026

    Single cell RNA-seq (scRNA) has provided unprecedented resolution into cellular and clonal heterogeneity. Computational approaches have enabled recovery of differentiation dynamics, yet current approaches do not evaluate discontinuous differentiation processes present in malignant leukemia. To address these gaps, we developed SupeRJump: a jump-drift-diffusion based supervised cell-fate model ( https://github.com/namwob44/SupeRJump/ ). We deploy this approach in human bone marrow, murine aging...

  • AllTheBacteria: a community resource empowers biology and discovers novel peptide antibiotics Friday, July 17, 2026

    Public microbial genomes encode an immense record of biological diversity, evolution and molecular function, but much of this information remains difficult to reuse because raw sequencing data are not uniformly assembled, quality controlled, annotated or searchable at scale. Here we present AllTheBacteria, an open, community-built resource that transforms public bacterial short-read whole-genome sequencing reads into a uniformly processed discovery platform. The current analysed release contains...

  • Metabolomics of <em>in vivo</em> inflammation identifies soluble sialic acid as a conserved myeloid-cell metabolite Friday, July 17, 2026

    During an immune response, metabolism changes dramatically. Metabolites are oxidized to power immune cell functions, serve as building blocks for proliferation, and act as effectors to regulate pathogen or host cells. Though metabolic changes in cultured cells have been studied extensively, metabolism changes in vivo are less understood. Here, we measured metabolomic changes across six mouse tissues in three models of immune activation: CpG-DNA cytokine storm, lymphocytic choriomeningitis virus...
