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., 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.

Jennifer M. Burg, M.D. | Transplant Surgery

Jennifer Burg, M.D., Research Resident

My Mentors

Susan Orloff, M.D., Dan Streblow, Ph.D., and Kristian Enestvedt M.D.

My Lab

Orloff/Streblow Transplant Lab

My Research

The Streblow/Orloff lab studies the role of CMV in rejection in a heterotopic rat heart transplant model. My project focuses on the role of lymphoid aggregates, present in latently infected hearts, in the acceleration of chronic rejection. My clinical projects include outcomes research on incidental hepatocellular carcinoma in the liver transplant population and the effect of laparoscopic vs. open live donor nephrectomy in pediatric renal transplant recipients.

Christopher Connelly, M.D. | Trauma Surgery

Christopher Connelly, M.D., Research Resident

My Mentors

Martin Schreiber, M.D. and Belinda McCully, Ph.D.

My Lab

Trauma Lab

My Research

My primary interests involve the coagulopathy of trauma, specifically the role the vascular endothelium plays in traumatic injury. I am currently investigating the expression of endothelial protein receptor C, thrombomodulin and other associated coagulation proteins using a rat model of obesity and hemorrhagic shock. I am also working on prospective randomized studies evaluating rates of venous thromboembolism and bleeding complications in trauma and surgical patients who receive dose adjusted prophylactic lovenox using thromboelastography.

Kelly Haisley, M.D. | Minimally Invasive Surgery

Kelly Haisley, M.D., Research Resident

My Mentors

James Dolan, M.D. and John Hunter, M.D.

My Lab

Foregut and Minimally Invasive Surgery

My Research

My research focus is on optimizing treatment strategies and outcomes in esophageal cancer. My main project is investigating a novel esophageal cytology device with the goal of providing widespread population based esophageal cancer screening in the United States for the first time.

Sheena Harris, M.D. | Vascular Surgery and KCVI

Sheena Harris, M.D., Research Resident

My Mentors

Greg Moneta, M.D., Erica Mitchell, M.D. and Amir Azarbal, M.D.

My Lab

Vascular Surgery Lab and the Knight Cardiovascular Institute

My Research

I am interested in clinical and outcomes research. I am establishing a basis of interpretation for lower extremity duplex values in patients with left ventricular assist devices, identifying drivers of diabetic foot ulcers to amputation, and investigating outcomes of patients transferred from outside hospitals to our vascular surgery department. I am also interested in quality initiatives, and am reviewing the effect of institutional policies on CAUTI rates.

Patrick McLaren, M.D. | Esophageal Diseases

Patrick McLaren, M.D., Research Resident

My Mentors

James Dolan, M.D. and John Hunter, M.D.

My Lab

Foregut and Esophageal Diseases Lab

My Research

We are investigating genetic predictors of pathologic complete response to neoadjuvant chemotherapy in esophageal cancer. Using RNA sequencing, we predict that we can identify genetic differences between esophageal tumors that respond favorably to chemotherapy and those that do not. Ultimately, this could provide valuable information to guide treatment decisions.

Darryl Schuitevoerder, MBBS | Surgical Oncology

Darryl Schuitevoerder, MBBS, Research Resident

My Mentors

John Vetto, M.D. and Andy Weinberg, Ph.D.

My Lab

Surgical Oncology Lab

My Research

I am working on both clinical and basic science projects. The basic science component is based out of the Earl A. Chiles Research Institute at Providence Portland Hospital. We are analyzing memory T cells populations, both CD4 and CD8, from the peripheral blood in patients treated with anti-OX 40 for progressive metastatic prostate cancer. My clinical focus is on melanoma where I am involved in several projects including looking at the effects of sentinel lymph node biopsy on clinical outcomes in patients ≥ 75 years old, the incidence and predictors of axillary web syndrome after axillary sentinel lymph node biopsy, and the surgical outcomes after nonvisualization of sentinel lymph nodes on preoperative lymphoscintigraphy.

Sarah Walcott-Sapp, M.D. | KCVI

Sarah Walcott-Sapp, M.D., Research Resident

My Mentor

Frederick Tibayan, M.D.

My Lab

Knight Cardiovascular Institute

My Research

I am using an ovine model to study the effects of intrauterine hypo- and hypertension and induced postnatal heart failure on the development of the cardiac valves and the aorta, and determine if these changes convey an increased risk of cardiovascular disease later in life. I am also working on a clinical project evaluating postoperative pain and nausea control in pediatric cardiac surgery patients, and an educational project assessing the efficacy of the cardiothoracic surgery department's simulation labs.

Justin J. J. Watson, M.D. | Critical Care

Justin Watson, M.D., Research Resident

My Mentors

Martin Schreiber, M.D. and Belinda McCully, Ph.D.

My Lab

Trauma and Critical Care Lab

My Research

I am working on a number of projects related to improving safety and optimization of blood products in the trauma and critical care setting. Other research areas of interest include cardiothoracic surgery, surgical education and coagulopathy of trauma.

Dale Wilson, M.D. | KCVI

Dale Wilson, M.D., Research Resident

My Mentor

Greg Moneta, M.D.

My Lab

Knight Cardiovascular Institute

My Research

I research clinical outcomes in vascular surgery currently focusing on end of life care, utilization of duplex ultrasonography in lower extremity arterial disease, utility of duplex ultrasonography velocities in predicting wound healing, and durability of autologous composite vein grafts in lower extremity bypass surgery. Additionally, we have a translational project looking at the use of a plasma biomarker to predict aortic aneurysm or dissection.

J. Davis Yonge, M.D. | Critical Care

J. Davis Yonge, M.D., Research Resident

My Mentor

Martin Schreiber, M.D.

My Lab

Trauma and Critical Care Lab

My Research

I am investigating a variety of areas related to trauma and critical care practices. Currently, my clinical projects include: 8 year review of the Trauma triage system at OHSU; building a clinical algorithm to better manage patients with traumatic hip dislocations; and efficacy testing for a new type of junctional tourniquet. For basic science research I am using flow cytometry to classify the proportion of microparticles in trauma patients.
