Associate Research Physician

Dr. Toubaji is a genitourinary (GU) pathologist. He  is interested in studying GU solid tumors, particularly prostate cancer. His research focuses on prostate cancer significant molecular alterations, diagnostic and prognostic biomarkers, and validation of artificial intelligence (AI) and deep learning algorithms for detection and grading of prostate cancer. 

Areas of Expertise

1) prostate cancer, 2) molecular genetics and biomarkers, 3) genitourinary malignancies

I am an academic genitourinary (GU) pathologist and I am passionate about studying the histological features of GU malignancies. However, I am very interested in studying the genetic alteration of these tumors, as I believe it is the path for the future in diagnostic pathology. As prostate cancer remains a major health problem in the world, discovery and addition of new biomarkers and genetic alterations enhances the accuracy of prostate cancer clinicopathologic parameters (PSA, Gleason grade, stage) for the decision-making process toward optimal patient clinical management. Furthermore, application of artificial intelligence (AI) and deep learning systems enhances our accuracy and consistency in detecting, targeting and evaluating prostate cancer.
