Title: Professor of Surgery; Assistant Dean for Graduate Medical Education; Residency Program Director; Vice Chair for Education
Research Focus: Palliative care, trauma, and education
Mackenzie Cook, M.D.
Title: Assistant Professor of Surgery
Research Focus: My research focus is on how to best bring primary palliative care to the bedside of critically ill and injured patients, regardless of their physical location. Surgical palliative care is a large and complex field. My focus is specifically on how we can best align patients goals / hopes with the realities of acute trauma care and complex critical care. This includes an educational component as we determine what skills are needed by what people in what circumstances, as well as a systems component focused on optimizing communication across the state.

Research Focus: I am interested in the biochemistry, epidemiology, and regulation of gamma prime fibrinogen. We have found that gamma prime fibrinogen levels are correlated with COVID-19 disease severity.

Darren Malinoski, M.D.
Title: Professor of Surgery
Research Focus: Maximizing every organ donation opportunity
- The Donor Management Research Inititiative (DMRI)
The DMRI focuses on optimizing the care of potential deceased organ donors such that we can maximize quality and quantity of organs available for transplantation. The first main project is the expansion of the United Network for Orgon Sharing (UNOS) donor management goals, (DMG) registry, it is a prospective database of all deceased organ donors from participating organ procurement organizations that includes their critical care parameters and graft outcomes. The second project is completing primary and secondary analyses of multi site "hypothermia vs machine prefusion to protect against kidney delayed graft function" randomized control trial.
