Research Experience

Resident David Hampton, M.D., recipient of the 2014 Raymond H. Alexander, M.D. Resident Paper Competition

Residents have the option to spend a full academic year in their fourth year of residency as a research resident. Permission to do a research year is highly competitive and requires that the resident attend and present at several research conferences throughout the year. Research residents must participate in the OHSU Research Fair and be open to exploring a variety of research within our divisions.

Residents that are interested in research must choose a mentor from the Department of Surgery faculty and then develop a research proposal to be submitted in December of their third year of residency. Once approved by the Research Committee, the residents will then complete one year of research under the direction of Bruce Wolfe, M.D., F.A.C.S., F.A.S.M.B.S. and Belinda McCully, Ph.D.  A second year of research is occasionally possible, as is research with off-site mentors. Contact for more information on the program and how to apply.

Jessica Ballou, M.D. | Trauma Surgery

Jessica Ballou, M.D., Research Resident

My Mentors

David Zonies, M.D., M.P.H. and Karen Brasel, M.D., M.P.H.

My Department

Trauma, Critical Care and Acute Care Surgery

My Research

My research is clinically based and focuses on quantitative and qualitative studies of geriatric trauma and palliative care. My main projects use the Oregon Trauma Registry to explore how trauma patients access OHSU and how advance directives (such as the POLST registry) impact trauma outcomes.

My Mentors

James Ross, Ph.D., Farah Husain, M.D., Paul Schipper, M.D.

My Lab

Ross Trauma Lab

My Research

My main research focus is on interventions in the treatment of non-compressible torso hemorrhage. My primary project involves development of a multi-functional resuscitation fluid for use in the pre-hospital setting in trauma. My other focus for research is in thoracic surgery education and surgical interventions for non-healing marginal ulcers.

Rebekah Macfie, M.D. | Cardiac Surgery

Rebekah Macfie, M.D., Research Resident

My Mentor

Frederick Tibayan, M.D.

My Lab

Cardiac Surgery

My Research

My research focus is the developmental origins of cardiac valve disease. My primary project is evaluating the impact of increased in utero systolic load and mechanical stress on valvular interstitial fibroblast cells to understand how the changes in cell signaling genes and extracellular membrane proteins impact valve function.

Sawyer Smith, M.D. | Trauma Surgery

Sawyer Smith, M.D., Research Resident

My Mentors

Martin Schreiber, M.D., Albert Chi, M.D., Arvin Gee, M.D., Ph.D.

My Lab

Trauma, Critical Care and Acute Care Surgery

My Research

My research focus is on improving the outcomes for our trauma and acute care surgical patients. My main project is investigating the use of mesenchymal stem cells for the prevention of acute respiratory distress syndrome after traumatic injury. I am also working on projects involved with targeted muscle reinnervation for upper extremity amputees along with various clinical outcome projects involving our trauma patients.

Tarin Worrest, M.D. | Minimally Invasive Surgery

Tarin Worrest, M.D., Research Resident

My Mentors

Brett Sheppard, M.D. and Erin Gilbert, M.D., M.C.R.

My Focus

Pancreatic surgery and minimally invasive surgery; opioid utilization in general surgery

My Research

My research focus is on minimally invasive surgical techniques for adrenalectomy and splenectomy. I am also studying pancreatic cancer after resection. My main projects focus on opioid use after a variety of surgical procedures.

Luai Zarour, M.D. | Surgical Oncology

Luai Zarour, M.D., Research Resident

My Mentors

Kevin Billingsley, M.D., Skye Mayo, M.D., M.P.H., Melissa Wong, Ph.D.

My Lab

Surgical Oncology

My Research

My research focus is understanding how tumor cells gain diversity and metastatic potential. My main project revolves around an exciting discovery that tumor cells can fuse with macrophages creating a hybrid cell that retains the properties of its parental cells. We are currently conducting experiments in colorectal cancer, colorectal cancer with liver metastases, pancreatic cancer and melanoma.
