A conceived model of “physician scientist” cultivation: exploring the double degrees of MD-PhD program
As China’s population ages and chronic diseases like cancer, heart conditions, and diabetes grow more common, the need for doctors who can both treat patients and pioneer medical breakthroughs has never been greater. Traditional medical training often splits clinical skills from research—leaving a critical gap for “physician scientists” who bridge these two worlds.
Researchers from Xi’an Jiaotong University’s Health Science Center (XJTU HSC) recently detailed a new program to fill this gap, publishing their findings in the Chinese Medical Journal in 2020. The Double Doctoral Program (DDP), an MD-PhD track, aims to train clinicians who are also skilled researchers—addressing China’s evolving healthcare demands while aligning with global trends in medical education.
Why Physician Scientists Matter
China’s 2012 medical education reforms (outlined by the Ministry of Education) emphasized internationalizing 8-year MD programs, recognizing that modern medicine depends on merging clinical practice with scientific inquiry. Many diseases—from rare cancers to drug-resistant infections—still lack curative treatments, and uneven healthcare access across China’s regions makes innovation even more urgent. Physician scientists, who understand both patient needs and lab work, are key to solving these problems.
Building on Global Partnerships
To design a world-class program, XJTU HSC partnered with three leading institutions: Emory University (U.S.), Karolinska Institute (Sweden), and Institut Pasteur (France). These collaborations have deep roots: Emory and XJTU have worked together since 1992, when they co-trained Chinese radiologists who later transformed the field nationwide. Today, joint research spans urology, oncology, and pediatrics. Karolinska’s Professor Rikard Holmdahl—a Changjiang Scholar—leads XJTU’s Inflammatory Disease Theme Center and has secured national research grants. A 5-year agreement with Institut Pasteur further expands opportunities for cross-border learning.
Who Gets In?
Only top students in XJTU HSC’s 8-year integrated MD program (the Zonglian Pilot Program) are eligible. Candidates must:
- Earn excellent grades in their MD coursework
- Pass ideology-morality and professional knowledge assessments
- Demonstrate research interest, basic science skills, and strong English proficiency
- Receive a faculty recommendation and pass a panel review
For Emory-bound students, the process includes custom online interviews with Emory professors—ensuring only the most capable, motivated candidates are admitted.
The “3-on-1” Mentorship Model
To support students, XJTU HSC uses a unique “3-on-1” mentorship system:
- Clinical Mentor (XJTU HSC): Oversees the student’s entire journey and clinical skill training.
- Basic Science Mentor (XJTU HSC): Guides research fundamentals and experimental design.
- PhD Mentor (Partner Institution): Provides specialized guidance during the student’s 2-year overseas stay.
This team approach addresses common PhD challenges—like balancing clinical work with lab time—and ensures students graduate on schedule.
What Students Do
During their 2 years abroad, students focus on advanced research while integrating clinical observations (a key advantage of their medical background). To graduate, they must:
- Meet XJTU HSC’s degree requirements (including a dissertation)
- Prove competence in both MD and PhD work
All students are fully funded by the China Scholarship Council, XJTU, and their host institution. Graduates get priority to work at XJTU or its affiliated hospitals—keeping talent in the system to benefit patients.
Early Progress and Long-Term Goals
The program has already sent 5 students to Emory (2017) and 9 more to Emory and Karolinska (2019). While long-term effectiveness needs further evaluation, the model shows promise for training elite physician scientists.
Challenges Ahead
Wider implementation faces two hurdles:
- Time: The DDP adds 2 years to an 8-year MD program, extending training to 10 years.
- Resources: Limited facilities, faculty, and funding restrict how many students can participate.
But the researchers argue that physician scientists are a long-term investment: they maximize limited healthcare resources, develop life-saving treatments, and raise the standard of care across China.
This study, led by Wei-Jiang Dong, Wen-Bin Liu, and colleagues from XJTU HSC, was published in the Chinese Medical Journal (2020, Volume 133, Issue 13).
