Roger Tieu, PhD

Why did you choose the University of Pittsburgh?

The University of Pittsburgh was a fitting choice for me given its rich history in immunology with pioneers such as Jonas Salk, the creator of the polio vaccine, and Thomas Starzl, who revolutionized the field of transplant immunology. In my eyes, the PMI represents an impressive graduate program that continues to evolve and has trained exceptional students that include MSTP students. Moreover, it is immediately clear that the faculty here are open and collaborative, which provides great training opportunities and fosters interdisciplinary work. Overall, these qualities and attributes led me to choose the University of Pittsburgh to be where I train as a physician-scientist.
