Clinical Research Engagement
Start building your research foundation early by connecting with cardiac, thoracic, and general surgery faculty during your first semester. Express your genuine interest in cardiothoracic surgery and your willingness to contribute to ongoing projects. Finding the right mentor is key, our Research Positions in the U.S. guide can help you identify strong mentorship opportunities.
Focus your efforts on clinical outcomes, quality improvement projects, or case series that can lead to abstracts, presentations, and publications.
- By the end of M1, aim to have 1–2 publications.
- By M2–M3, strive to lead or co-author 4–5 research projects in cardiothoracic surgery to demonstrate both initiative and academic depth.
To accelerate your progress, we highly recommend enrolling in The Match Guy’s Research Course and Statistics Course—they’re designed to teach you how to design, analyze, and publish research effectively.
Depending on your goals and progress, we can also discuss the option of taking a dedicated research year to further strengthen your application.

Mentorship & Shadowing
Identify a cardiothoracic surgery mentor early—ideally a faculty member actively involved in research, education, or residency recruitment. Early mentorship provides invaluable guidance, professional connections, and insight into the specialty.
Begin shadowing cardiothoracic and general surgeons to gain hands-on exposure, develop your clinical perspective, and confirm your long-term interest in the field. Whenever possible, attend grand rounds, morbidity and mortality (M&M) conferences, and CT surgery case observations to deepen your understanding of surgical decision-making and patient care.

Extracurriculars & Service
Get involved early by joining your school’s surgery interest group and aim to take on a leadership role by M2, this demonstrates initiative, teamwork, and sustained commitment to the field.
Engage in meaningful volunteer work, especially in patient-facing roles or with underserved communities, to showcase your compassion, communication skills, and dedication to service.
Consider participating in community outreach, premed mentoring, or health education initiatives, these experiences highlight both your leadership potential and your broader impact beyond academics.

Strategic Planning & Networking
Start organizing your journey early by building a CV tracker from day one to record your activities, research projects, publications, leadership roles, and honors. Keeping this updated will make your application process smoother and more professional.
By M2–M3, aim to attend national or regional conferences, such as the Society of Thoracic Surgeons (STS), American Association for Thoracic Surgery (AATS), or local American College of Surgeons (ACS) chapters, to network, present your work, and connect with mentors in the field.
By M4, explore away rotations in cardiothoracic surgery to gain advanced clinical exposure and secure strong letters of recommendation from U.S. faculty.
Don’t risk your residency match chances with an average ERAS application. Allow our experts to enhance your accomplishments using our comprehensive ERAS CV editing services.
Your roadmap:
✅ Pre-clinical years: Focus on excelling academically, finishing Step 1, learning research methods, and building relationships with CT surgeons at your institution.
✅ Clinical years: Complete Step 2, continue research involvement, and consider a dedicated research year if you need to strengthen your application.
