Fellow Research

Research Training during Fellowship

Washington University NNICU is a world leader in translational research. Fellows have almost limitless opportunities for involvement in research at any level. All fellows receive research mentorship from the ICU faculty including Dr. Michael Diringer, Dr. Rajat Dhar, and Dr. Terrance Kummer. Additionally, they will work directly with faculty to refine their ability to evaluate scientific literature and present their research. Most fellows go on to present their projects at the annual Neurocritical Care Society Meeting.
