Dr. Donnele Daley is a faculty member within the Section of General Surgery at the University of Michigan.

Dr. Daley graduated from Dartmouth College with a Bachelor of Engineering and Vassar College with a Bachelor of Arts in Physics and Mathematics. She graduated with General Honors and was elected to the Phi Beta Kappa Honor Society. She earned her medical degree from Penn State College of Medicine after which she was accepted into the General Surgery Residency program at New York University Medical Center. During her time at NYU, she spent two years in a postdoctoral research fellowship studying tumor immunology and the biology of pancreatic cancer, which fueled her interest in oncology research and cancer care. Upon finishing her General Surgery residency, she completed a fellowship in Surgical Oncology at Memorial Sloan-Kettering Cancer Center in New York.

Dr. Daley is a practicing general and oncologic surgeon at the University of Michigan. Her practice encompasses gastrointestinal malignancies, and she specializes in gastric and peritoneal malignancies. Dr. Daley is trained and certified in Minimally Invasive and Robotic Surgery techniques.

Dr. Daley's lab seeks to understand and describe systems that alter immunological homeostasis in pancreatic cancer. She is particularly interested in understanding how the human microbiome contributes to immune cell-regulated tumor escape. Ultimately, she hopes to uncover distinct mechanistic pathways connecting the human microbiome and various components of the tumor microenvironment, that are novel targetable strategies for treating this disease.
