Daniel James Firl
Clinical Instructor, Surgery - Abdominal Transplantation
BioDaniel Firl is an abdominal transplant surgery fellow at Stanford Medicine and a surgeon-scientist working at the intersection of hepatobiliary cancer surgery and transplantation. His work centers on patient selection in primary liver cancer — determining which patients are best served by resection and which by transplantation — and on the risk-assessment tools that make that decision more precise.
He is a co-developer of HALT-HCC, a risk model for liver transplantation in hepatocellular carcinoma, and first author of its international validation across more than 4,000 patients. His aim is to make selection between resection and transplantation progressively more sophisticated — sharpening prediction of waitlist and post-transplant outcomes, informing donor selection, and enabling the safe use of grafts that might otherwise be declined — with a particular interest in intrahepatic cholangiocarcinoma and gallbladder cancer, where the role of transplantation is still being defined. He sees the next step as the integration of tumor genomics, bringing the molecular features of each cancer into the models that guide surgical decisions.
Earlier, during postdoctoral training at the Massachusetts General Hospital, he studied the immunology and physiology of kidney xenotransplantation, including the design and long-term function of organs from genetically engineered porcine donors — part of the broader effort to expand the supply of transplantable organs.
Dr. Firl completed general surgery residency at Duke University, where he served as chief resident, and earned his MD with Special Qualifications in Biomedical Research through the research-intensive program at the Cleveland Clinic Lerner College of Medicine of Case Western Reserve University. He holds a bachelor's degree in biochemistry from Boston College.
He is the author of over 30 peer-reviewed articles, with work in Nature, Cell, The Lancet Gastroenterology & Hepatology, Hepatology, and The Lancet Digital Health. He serves as an ad hoc reviewer for journals including The BMJ, Kidney International, the American Journal of Transplantation, JCO Precision Oncology, and Transplantation.
He has received fellowships and grant funding from prestigious organizations during competitive funding opportunities including from: the NIH-NIAID, Howard Hughes Medical Institute, and the American Society of Transplantation. -

John V. Gahagan, MD, FACS, FASCRS
Clinical Associate Professor, Surgery - General Surgery
BioJohn V. Gahagan MD is a Clinical Associate Professor in Colon & Rectal Surgery. He leads the Colon & Rectal Surgery residency program as Program Director and serves as Chief of Surgery and the Medical Director of Supply Chain at the Stanford Tri-Valley Hospital. He joined Stanford in 2019 to build the Stanford Colon & Rectal Surgery practice in the East Bay at Stanford Tri-Valley in Pleasanton and at Stanford Health Care – Emeryville. He has training in advanced minimally invasive surgical techniques including robotic and laparoscopic surgery. He has authored several textbook chapters and original articles in peer-reviewed journals. His clinical practice is focused on the surgical treatment of colon and rectal cancers, inflammatory bowel disease (ulcerative colitis and Crohn’s disease), and benign colon and anorectal diseases (diverticulitis, hemorrhoids, fistulas, fissures). He believes in patient-centered care and multi-disciplinary approach to the treatment of diseases of the colon, rectum and anus.
Dr. Gahagan is passionate about surgical education. He serves as an Associate Program Director of the Stanford General Surgery Residency Training Program. In that role, he oversees resident evaluation and feedback. He led the revamp of the program’s evaluation process and Clinical Competency Committee – work that has been presented at the Association of Program Directors in Surgery (APDS) and the Accreditation Council for Graduate Medical Education (ACGME). In 2021, he established the Stanford General Surgery Endoscopy rotation, giving general surgery residents an opportunity to gain endoscopy experience by collaborating with faculty gastroenterologists and fulfilling their graduation requirements. In 2026, he established the Colon & Rectal Surgery residency program at Stanford and serves as the Program Director. At the time of accreditation, this program was the only ACGME accredited Colon & Rectal Surgery residency program in Northern California. In addition, he is the General Surgery Rotation Director for the Stanford Tri-Valley Family Medicine Residency. On a national level, he is an associate question writer for the American Board of Colon & Rectal Surgery and serves on the USMLE Step 3 Test Development committee and the USMLE Management Committee.
He also serves in various administrative roles, including as Chief of Surgery at the Stanford Tri-Valley Hospital. In 2025, he was appointment Medical Director of Supply Chain for the Stanford Tri-Valley Hospital. He is a member of the Stanford Medicine Partners Quality and Credentialing Committee, the Stanford Tri-Valley Operating Room Committee and the Stanford Tri-Valley Medical Executive Committee. -

Laura Graham
Other Teaching Staff-Hourly, Surgery
BioI am an epidemiologist and health services researcher with nearly 20 years of experience in surgical outcomes research. My work focuses on improving healthcare delivery and outcomes for Veterans and other vulnerable populations, particularly those who are older or medically complex. Using large administrative datasets from the Veterans Health Administration (VA), I study surgical processes and outcomes to inform system-level improvements.
With postdoctoral training in health economics and implementation science, I bring expertise in causal inference methodology and artificial intelligence, particularly the use of natural language processing (NLP). I apply these methods to extract insights from unstructured clinical data and to strengthen causal analyses in complex healthcare datasets. These approaches allow me to address research questions that were previously difficult to study with standard empirical approaches.
As a collaborative leader, I have mentored junior investigators and worked across academic and industry sectors to advance health services research. My goal is to translate evidence into practice, ultimately improving the quality of surgical care for Veterans.
