Research Interests

Radiosensitizers; Genetically engineered mouse models of disease; Epithelial Plasticity (Epithelial-Mesenchymal Transition and Mesenchymal-Epithelial Transition)
Dr. Tran's research focuses on the improvement of clinical radiotherapy for the treatment of adrenal, bladder, penile, prostate, testicular and urethral cancer. To learn how tumors grow and why some cancers are resistant to treatment, he studies the transitions of epithelial and mesenchymal cellular states in transgenic mouse models.

Additionally, Dr. Tran is working with colleagues from top-ranked institutions nationwide to establish a National Radiation Oncology Registry. The purpose of the registry is to improve the care of cancer patients by capturing and studying information about cancer treatments and outcomes.


Dr. Phuoc T. Tran is an associate professor of radiation oncology and molecular radiation sciences, oncology and urology at the Johns Hopkins School of Medicine.

Dr. Tran is the Clinical Director of Radiation Oncology at the Sidney Kimmel Comprehensive Cancer Center and treats patients with cancers of the genitourinary system and uses stereotactic radiation techniques (such as SRS and SBRT/SABR) for the treatment of patients with oligometastatic disease. His research focuses on the improvement of clinical radiotherapy for the treatment of adrenal, bladder, penile, prostate, testicular and urethral cancer as well as patients with oligometastatic disease.

Dr. Tran and his laboratory focus their studies on the transitions between epithelial and mesenchymal cellular states and the implications of these transitions for tumorigenesis, cancer treatment resistance and radiation-induced fibrosis. Their research utilizes a variety of inducible transgenic mouse models and non-invasive rodent imaging.

One of these transitions, known as epithelial-mesenchymal transition (EMT), is a conserved developmental program that when inappropriately activated in post-natal life has been associated with organ fibrosis, tumorigenesis and metastasis. A major focus of the laboratory is the use of inducible mouse models to simulate molecularly targeted therapies for malignancies and radiation induced late effects. Another focus of the laboratory is the study of novel targeted agents as tumor selective radiosensitizers to increase the therapeutic ratio of clinical radiotherapy.

The Tran lab is committed to translating discoveries from the laboratory bench into novel cancer prevention, diagnostic and treatment approaches that can be tested in the clinic.
