Julie K. Schwarz

Julie K. Schwarz, MD, PhD, FASTRO is a tenured Professor of Radiation Oncology at Washington University School of Medicine, where she serves as Vice-Chair of Research and Director of the Cancer Biology Division. She also holds appointments as Professor of Cell Biology and Physiology and is affiliated with the Roy and Diana Vagelos Division of Biology & Biomedical Sciences, specifically within the Cancer Biology and Molecular Cell Biology programs. Dr. Schwarz is a key member of the Siteman Cancer Center and co-leads one of only five centers comprising the NIH's Radiation Oncology-Biology Integration Network (ROBIN).

Dr. Schwarz completed her BS in Biology at Duke University (1995) followed by an MD/PhD in Cell and Molecular Biology at Washington University School of Medicine (2004) through the Medical Scientist Training Program. She completed her Internal Medicine internship (2005) and Radiation Oncology residency (2009) at Barnes-Jewish Hospital, becoming board-certified by the American Board of Radiology in Radiation Oncology (2010).

Her research program focuses on translational studies of gynecologic cancers, particularly cervical cancer, with emphasis on tumor metabolism, biomarker discovery, and treatment resistance mechanisms. Dr. Schwarz's laboratory maintains one of the largest tumor repositories for cervical cancer, which includes specimens collected before and during chemoradiation treatment. Her work has demonstrated the critical role of pretreatment and post-treatment FDG-PET scanning for cervical cancer patients and has identified alterations in PI3K/Akt pathway genes associated with treatment response. Recent research directions include studying obesity's paradoxical favorable impact on cervical cancer outcomes, glucose and glutamine metabolism as targets for cancer therapy, and the role of tumor immunology in therapy resistance.

Analysis of Dr. Schwarz's most recent publications reveals a strong focus on cervical cancer biology, tumor metabolism, and novel therapeutic approaches. Her work integrates clinical data with laboratory research to identify biomarkers and develop improved treatment strategies. Current research emphasizes the interface between tumor metabolism, the microenvironment, and response to therapy, with particular attention to HPV-related cancers, tumor imaging, and metabolic targets for radiosensitization.

• Fellow of American Society for Radiation Oncology (ASTRO) (2024)
• Danforth WashU Physician-Scientist Scholar Award (2024)
• Elected into American Society for Clinical Investigation (2022)
• Michael Fry Research Award for Outstanding Junior Investigator: Radiation Research Society (2012)
• Fellow: National Cancer Care Network (2008)
• RSNA Roentgen Resident/Fellow Research Award (2008)

As a dedicated mentor, Dr. Schwarz has guided numerous trainees across all levels including undergraduates, graduate students, medical students, residents, fellows, and postdoctoral researchers. Her Schwarz Lab is highly collaborative and actively recruits students and researchers, with recent successes including Leahan Castillo receiving an Honorable Mention at AACR and Brett Tortelli developing significant research on the vaginal microbiome's relationship to cervical cancer treatment response. Dr. Schwarz is R01-funded and leads multiple research projects, including work on the TARGET Center which focuses on understanding the biologic effects of radiation therapy in cancer treatment. She actively participates in national organizations including the ASTRO/NCI Radiobiology Consensus Workshop, AACR Radiation Oncology Think Tank, and the ASTRO Community of Radiation Oncology Physician Scientists.

Dr. Schwarz directs the Schwarz Lab, which is growing and actively recruiting postdocs, staff scientists, and graduate students. The lab employs a multidisciplinary approach combining well-annotated clinical databases, prospectively collected patient tumor banks, and state-of-the-art sequencing technologies. Current research directions include single-cell sequencing approaches to study treatment effects on tumor cells and immune cells within the tumor microenvironment, glucose and glutamine metabolism as targets for cancer therapy, and targeting myeloid-derived cells to improve anti-tumor immunity. The lab is highly collaborative and studies multiple tumor types including cervical, pancreatic, and ovarian cancers.
