Memphis at Work: University of Tennessee Health Science Center

Weili Sun, MD, PhD, traveled to Memphis from China in 1998 to pursue a PhD in pathology at UT Health Science Center. She had not been back to Memphis since leaving in 2005 for postgraduate medical training, until she was invited to give the keynote address at the university’s Winter Postdoc Research Showcase.

Now senior medical director for oncology clinical research at Johnson & Johnson Innovative Medicine, Sun offered researchers advice on pursuing a career in the pharmaceutical industry. She also spoke fondly of the two Memphis institutions—UT Health Science Center (UTHSC) and St. Jude Children’s Research Hospital—that helped shape her career.

“I think all the mentors, the things I learned, also the skills I learned as a PhD helped me a lot, not only as a clinical investigator in academia, but also in the pharmaceutical industry,” Sun said. “I’m still using those things in my daily work.”

Sun reminisced about her time as a graduate student in the lab of James R. Downing, MD, now St. Jude president and CEO. Sun’s training in Memphis exemplifies the longstanding collaboration between UTHSC and St. Jude in developing future scientists and conducting research.

More recently, Mikayla Harden-Pruitt, a graduate student at UTHSC, has benefited from the collaboration.

She works in the lab of Victor Torres, PhD, Department of Host-Microbe Interactions chair.

“Being a UT Health Science Center student and working in a St. Jude lab has helped me in several ways,” she said. “St. Jude is very collaboration-oriented, and the Host-Microbe Interactions department studies many different pathogens, so I can easily gain experience cross-training in various research fields and with different pathogens.”

As Tennessee’s only public, statewide academic health science institution, UTHSC is the state’s largest educator of health care professionals. Since its founding in 1911, UTHSC has educated and trained approximately 54,000 health care professionals through its six colleges and four campuses.

Faculty physicians, residents, as well as supervised students, are researchers and care providers for patients in hospitals and clinics across Memphis and the region. UTHSC physicians and researchers are also among the staff at several health care institutions across Tennessee.

Through partnerships with major hospitals in Tennessee’s largest cities, as well as 779 clinical and education sites, UTHSC students, trainees, residents, and faculty provide high-quality health care to the people of Tennessee.
