Rutger-Jan Swijnenburg
Amsterdam University Medical Centers

As a Hepato-Pancreatico-Biliary (HPB) Surgeon in the Amsterdam UMC (a recent merger of the AMC and VUmc), Dr. Swijnenburg’s research focusses on multimodality molecular imaging to allow integration of diagnostic and intraoperative imaging in patients suffering from tumors in the liver, pancreas and biliary tract.
After obtaining his medical degree in 2006, he spent three years at Stanford University studying molecular imaging of embryonic stem cell transplantation, for which he received a PhD degree at the Leiden University (Prof. dr. J.F. Hamming, Prof. Dr. R.C. Robbins and Dr. J.C. Wu). This research was supported by grants from the European Society for Organ Transplantation and the Fulbright Foundation. Upon returning to The Netherlands, he started Surgery Residency at the Leiden University Medical Center and the Bronovo Hospital in The Hague. He became interested in surgical oncology, specifically hepatobiliary and pancreatic cancers and got the opportunity to join the Image-Guided Surgery research group (Prof. Dr. C. van de Velde, Dr. A.L. Vahrmeijer) at the LUMC. In 2011, he worked full time for a year as a post-doc. In 2010, he co-founded the Lisa Waller Hayes Foundation ( This foundation is dedicated to advance scientific research in the field of pancreatic cancer and to provide a platform of information to patients and their families. After finishing training as a surgical oncologist in July 2015, he did a 2-year fellowship in HPB surgery at the LUMC. During that time, he instigated renewed collaboration with Stanford University’s Multimodality Molecular Imaging Lab (Prof. Dr. S.S. Gambhir) and gathered funding from several sources to allow PhD and graduate students to spent 1-2 years at Stanford. Joint projects primarily focus on the development and clinical translation of molecularly-targeted, tumor-specific imaging agents. In August of 2018, he was appointed staff member in HPB surgery at Amsterdam UMC. In that same year, he was awarded a Young Investigator Grant by the Dutch Cancer Foundation (KWF), which has allowed him to form his own research group. Currently, he is the supervisor of 5 PhD candidates and several graduate students at Amsterdam UMC and the LUMC. His clinical focus is mainly on colorectal liver metastases, cholangiocarcinoma and pancreatic cancer.


T. Peter Kingham, USA
Memorial Sloan Kettering Cancer Center

Peter Kingham was appointed to the staff at Memorial Sloan Kettering Cancer Center (MSKCC) on the Hepatopancreatobiliary Surgery Service in August, 2010. Prior to my appointment I completed a two-year fellowship in surgical oncology at MSKCC. I am also co-founder of a non-profit organization called Surgeons OverSeas. Since 2001 I have been collaborating with surgical colleagues in sub-Saharan Africa working on surgical oncology and general surgical development projects. My early research demonstrated the importance of surgery as a component of public health. Now, my research is focused on defining disparities in cancer care, cancer outcomes, surgical oncology training, and introducing new diagnostic tests in low- and middle-income countries. After documenting the differences in the metastatic presentation of patients with colorectal cancer in Nigeria, prospective studies exploring these differences and community based screening projects for colorectal cancer are underway. We have also formed a consortium of investigators in 5 hospitals in Nigeria centered on gastrointestinal malignancies. This project has created a robust clinical, pathologic, and radiologic database with good quality assurance. I have mentored and trained surgeons from Nigeria, Sierra Leone, Ghana, Kenya, Rwanda, and Malawi. As the Director of Global Cancer Disparity Initiatives at MSKCC I am now expanding our training and research efforts to additional sites in Africa.
