Research Resident Spotlight - May 2024

Tell us a little about your path to Surgery Residency.Paul Burchard

My interest in surgery stemmed largely from my father, who was a trauma, acute care, and critical care surgeon. For my undergraduate degree at the University of Richmond, I pursued a BS in biology and minor in medical humanities, which included a semester abroad at the Danish Institute studying medical practice and policy. Following graduation, I spent two years in a molecular pathology lab at Dartmouth Hitchcock Medical Center. Through this experience, I expanded my knowledge in basic science research and manuscript writing, and was fortunate to matriculate into West Virginia University School of Medicine. While in medical school, I solidified my surgical interest by completing a surgical externship between my first and second year. I was selected as a leader for the medical school's Surgery Interest Group, organizing multiple activities between medical students and surgical residency program at WVU. Following clinical rotations, I was inducted into the Gold Humanism Honor Society and was elected president of the Alpha Omega Alpha Honor Society. With my wife pursuing a career in pediatrics, we both matched and were thrilled to join the University of Rochester Medical Center for our training!

 

What was your motivation to pursue research during your residency?

During my first two clinical years in our general surgery program, I developed a keen interest in surgical oncology. There were multiple clinical aspects and biological characteristics of cancer patient care that I wanted to explore and understand further. I decided to join Dr. Linehan's lab because this offered me the opportunity to apply my basic sciences background and further pursue my career interest, while providing the foundation for understanding how to improve perioperative care.

What does the role of mentorship in research mean to you?

Research mentors take on the unique task of unbiased guidance towards the career and personal goals we set forth as trainees. Often these goals change over the course of our research and strong mentors are able to adapt and maintain a positive influence. My mentors have all emphasized my growth as a researcher, clinician, and person during the three years I spent in the lab while becoming friends and colleagues throughout the process.

 

What is your research focus?

My research focused on targeting the highly treatment-resistant tumor microenvironment of cholangiocarcinoma by utilizing a novel agent that disrupts collagen-crosslinking to alter the tumor matrix. Through this project, we were able to reduce tumor stiffness and augment chemotherapeutic penetration to improve tumor control and survival in mouse models of cholangiocarcinoma. Notably, our efforts also shifted the immune cell composition to favor anti-tumor immunity and functionally disrupted immunosuppressive macrophage migration/invasion into the tumors, revealing another link between tumor stroma and immunity in cholangiocarcinoma.

What are your future goals?

I am looking forward to the publication of my basic science research project that was the result of my 3 years in Dr. Linehan's lab as well as my upcoming surgical oncology fellowship application. I would like to pursue a career in surgical oncology that will combine university and community practice to provide a conduit for surgical care in cancer patients.
