About Dr. Zhang
Jun Zhang, MD, PhD, is an internationally recognized physician scientist and academic leader in thoracic oncology and translational cancer research. He serves as the Petrakis Endowed Chair and vice president of oncology research at the OSF HealthCare Cancer Institute, where he leads strategic scientific initiatives and advances precision oncology across the enterprise. He is also professor at the University of Illinois College of Medicine and the University of Illinois Urbana-Champaign, and adjunct professor at the Translational Genomics Research Institute.
Dr. Zhang completed his medical training at the Xiangya School of Medicine, earned a PhD in Cancer Biology from Louisiana State University, and pursued postdoctoral research at Harvard Medical School and the University of California San Francisco, followed by a hematology/oncology fellowship at Emory University School of Medicine. His career integrates foundational discovery with clinical translation, exemplified by his leadership in developing innovative investigator-initiated trials and advancing microbiota-informed cancer therapeutics.
He has authored more than 100 peer-reviewed publications, including many in high-impact journals such as Cancer Cell, Nature Communications, Clinical Cancer Research, JAMA Oncology, Molecular Cancer, Annals of Oncology, and The New England Journal of Medicine. A dedicated member of the global oncology community, Dr. Zhang contributes to AACR, ASCO, ESMO, IASLC, the Royal Society of Medicine, and Sigma Xi.
Dr. Zhang’s research program centers on three interconnected pillars: The role of the microbiota and its extracellular vesicles in lung cancer biology and immunotherapy; mechanisms of resistance in oncogene-driven non-small cell lung cancer; and the design of novel translational and interventional studies for thoracic malignancies. His work continues to shape emerging ideas at the interface of tumor immunology, microbiome science and precision medicine.

About Dr. McWilliams
Robert McWilliams, MD, is an internationally recognized clinician, clinical trialist and leader in gastrointestinal oncology and skin cancers. He serves as deputy director of the OSF Cancer Institute, where he continues his clinical trials and outcomes research while helping transform cancer clinical practice.
Dr. McWilliams earned his medical degree, summa cum laude, from Georgetown University School of Medicine and completed his residency in internal medicine at Johns Hopkins University. He then completed a hematology/oncology fellowship at Mayo Clinic in Rochester, Minnesota, along with a genetic epidemiology research fellowship and a master’s degree in clinical research.
He spent 20 years on the faculty at Mayo Clinic, rising to the rank of professor and serving in numerous leadership roles, including clinical practice chair of medical oncology, vice chair of oncology, deputy director of cancer practice, chair of the biospecimens subcommittee and chair of the therapeutic strategy subcommittee. He led the redesign of the medical oncology care model, optimizing each team member’s role to practice at the highest level of their training. He also expanded the cancer center’s patient navigator program, led the adoption of the Epic electronic health record for hematology and oncology, pioneered the use of patient-reported systems to address financial barriers and established the first precision oncology clinic.
Dr. McWilliams has authored more than 180 publications in high-impact journals, including The New England Journal of Medicine, JAMA, JAMA Oncology, Lancet Oncology, Journal of Clinical Oncology, Nature Genetics, Gut and Clinical Cancer Research. He has served in numerous national and international roles, including on the National Cancer Institute’s pancreatic cancer task force and GI cancers steering committee and as the U.S. lead for small bowel adenocarcinoma in the International Rare Cancers Initiative. His work with the National Comprehensive Cancer Network has included service on the board of directors, the finance committee, the electronic health records subcommittee and the best practices committee. He has also served on the Epic adult oncology advisory board.
His career has focused on using genetic information to advance patient care and leveraging emerging technology to improve cancer care at a population level. He believes technology can enhance prevention, detection and treatment while also strengthening the human experience for both patients and providers.

About Dr. Tsung
Andrew Tsung, MD, MBA, FAANS, is a physician-scientist and neurosurgical oncologist at OSF HealthCare. He serves as vice president of OSF HealthCare Illinois Neurological Institute (INI), where he leads the neurosurgery, neurology and physiatry divisions in strategic growth initiatives and daily operations. Dr. Tsung also serves as the Patrick Elwood Endowed Chair in the Department of Neurosurgery at the University of Illinois College of Medicine, and as program director of the University of Illinois College of Medicine at Peoria (UICOMP) Department of Neurosurgery Residency Program. In addition, he is codirector of the Molecular Translational Oncology Laboratory at UICOMP alongside Kiran Velpula, PhD.
Dr. Tsung earned his medical degree from Southern Illinois University School of Medicine, graduating with Alpha Omega Alpha (AΩA) honors. He completed his neurosurgery residency at UICOMP and subsequently pursued fellowship training in neurosurgical oncology at The University of Texas MD Anderson Cancer Center under the mentorship of pioneering neuro-oncologic surgeon Raymond Sawaya, MD. He later returned to the University of Illinois to complete an MBA focused on business analytics, aligning clinical and research strategy with the broader objectives of UICOMP and INI. To further support his research, he is also completing a Master of Science in Applied Physics at Johns Hopkins University.
Dr. Tsung’s research integrates metabolic therapeutics for high-grade glioma with the physical principles underlying cellular division. In the Molecular Translational Oncology Laboratory at UICOMP, his team studies metabolic checkpoints that regulate how cancer cells use and dissipate energy during cell division. High-grade gliomas often exploit adaptive metabolic bypass pathways to sustain growth and proliferation, and these mechanisms represent key therapeutic targets under investigation by Dr. Tsung and his team. This work has led to multiple research grants, peer-reviewed publications and a patent-pending therapeutic strategy involving 3-Phosphoinositide-dependent kinase 1 (PDK1) inhibitors for the treatment of glioblastoma.
