Physician-scientists are a group of specialized researchers at the intersection of medicine and technology. Earning both medical degrees and Ph.D.s, they offer a perspective beyond the scope of clinical practice.
Three such researchers discussed how they make the connections between discovery and patient care.
Why a Dual Education Matters
Shaun Xiaoliu Zhang, director of the Center for Nuclear Receptors and Cell Signaling at the University of Houston and M.D. Anderson Professor of Biology and Biochemistry, knows exactly what the clinical demands are.
“I can see from the M.D. perspective, but at the same time I have a Ph.D. – I know how to design research properly,” he said. “In the clinic, you’re faced with reality that a patient is struggling but you don’t have the tools to treat those patients. If you engage in research you can create a tool.”
Zhang said clinicians know the need but may struggle to design a solution. A Ph.D., on the other hand, may only know basic research.
Renowned hormone researcher Jan-Åke Gustafsson, Robert A. Welch Professor of Biology and Biochemistry and founding director of the Center for Nuclear Receptors and Cell Signaling, agrees.
“The dual education makes it possible for you to see which diseases are in need of more research, drugs and so on,” he said.
Physician-scientists are the driving force behind many advances of modern medicine.
“The way I look at it is, practicing medicine is relatively easy but coming up with the next diagnostic device or the next treatment for a disease is way more difficult, way more challenging,” said Chandra Mohan, Hugh Roy and Lillie Cranz Cullen Endowed Professor of Biomedical Engineering at UH.
“You see patients with certain diseases, and you know there’s a dire need for better diagnostics, earlier treatment, earlier diagnosis with fewer side effects,” he said.
While researchers spend time primarily in the laboratory and clinical practitioners interact with patients, they both want to make an impact.
“We have made some discoveries which have led to the development of new drugs and better understanding of certain diseases,” says Gustafsson. “There’s a great satisfaction that it may help people to get healthy.”
Translational Research Brings Value to the University
The synergy of this dual education makes these investigators valuable not only to academia, but also to medical science.
“I can’t imagine doing translational research without medical training,” Zhang said. “If you have this part without the other, you don’t know where to go. With medical training, you know exactly which direction to go.”
Mohan echoed that assessment.
“When you start doing research there are so many questions you can answer,” he said. “Sometimes there are questions which are just too basic. They’re too far removed from how it will impact a patient’s life. So what are the most important questions? I think questions that really make a difference in the patient’s life are the most important.”
Zhang noted that the National Institutes of Health has switched its funding philosophy – once focused on basic science, it now is more interested in translational research, with a direct relationship to patient health.
As physician-scientists, these “translators” of medical research are able to bridge the chasm.
Amr Elnashai, vice president/vice chancellor of research and technology transfer at UH, said physician-scientists play an important role.
“The increasing importance of deploying technology in medicine renders it essential for a progressive research university to hire medical Ph.D. holders who are in an ideal position to bridge the gap between engineering and science on the one hand, and the broad field of medicine on the other,” he said.
Research groups that bring both fields together not only have a much higher probability of impacting lives by adopting the latest technology in medical applications, he adds, but they also give interdisciplinary teams greater access to specific funding pursue such solutions.
In that sense, said Elnashai, medical Ph.D. researchers play an important part of the future research university.
