Juan Figueroa, MD
Dr. Juan Figueroa is a foreign medical graduate from Ecuador who is working as a Research Fellow in the Division of Trauma and Acute Care Surgery at MCW. His collaborative research alongside with our faculty aims at improving clinical outcomes in the injured patient, development of quality-of-life prediction models after traumatic brain injuries, and trauma system development in low- and middle-income countries, projects that have gained interest among the trauma community and have led him to present at local and national surgical meetings. His research methods include the use of registry data, prospective interventional studies, and qualitative research.
Katherine Flynn-O'Brien, MD, MPH
Timothy Geier, PhD
Dr. Timothy Geier is an Assistant Professor in the Departments of Surgery and Psychiatry and Behavioral Medicine. His research interests include biopsychosocial risk factors for the development of trauma-related conditions (e.g., PTSD) following traumatic injury and acute medical illness, PTSD and depression screening and treatment, impact of socioenvironmental stressors on mental health outcomes, and health disparities following injury and illness.
Daniel Holena, MD, MCSE
Dr. Holena is an Associate Professor of Surgery and serves as Director of Research for the Division of Trauma and Acute Care Surgery. His research interests include trauma systems, the use of audiovisual recordings to improve processes of care in trauma resuscitation, and the application of the Failure to Rescue (FTR) metric to trauma populations.

Rachel Morris, MD
Dr. Rachel Morris is an Assistant Professor of Trauma and Acute Care Surgery and Associate Director of Research. My research interest is model guided decision support using machine learning. Specifically, direct applications include shared decision-making in older adults and optimization of the trauma triage process. Through mobile application invention and development, we focus on directly applying complex models to patient care. My research is currently funded through The Eastern Association for the Surgery of Trauma.
Jacob Peschman, MD
Dr. Peschman is an Assistant Professor of Surgery and serves as the Chair of Froedtert’s Trauma Education Committee and as an Associate Program Director of the General Surgery Residency Program.

Courtney Pokrzywa, MD
Dr. Courtney Pokrzywa is a General Surgery Resident currently in her professional development year serving as one of our Research Fellows in the Division of Trauma and Acute Care Surgery. She is currently involved in several projects centered around the evaluation and optimization of current clinical practices to improve patient outcomes. From large dataset, registry, and prospectively collected trauma and acute care surgery clinical outcomes projects to predictive modeling, model guided decision support, and hands-on clinical trials, she works alongside many of our Trauma and Acute Care Surgery faculty and MCW residents and provides mentorship to current medical students.
Andrew Schramm, PhD
Dr. Andrew Schramm is an Assistant Professor of Surgery in the Division of Trauma and Acute Care Surgery. He has a joint appointment in the Department of Psychiatry and Behavioral Medicine.
