Welcoming New Faculty – Matthew Pommerening, MD

Please join us in welcoming Matthew Pommerening, MD, as a new faculty member in the Department of Surgery.

Matthew Pommerening, MD
Associate Surgeon, Division of Thoracic Surgery

Dr. Pommerening is a graduate of the University of Texas at Austin. He received both his medical degree and general surgery training from the University of Texas McGovern Medical School in Houston, where he also spent time studying clinical outcomes after traumatic injury. He went on to complete a cardiothoracic surgery residency at the University of Pittsburgh Medical Center followed by a thoracic surgery fellowship at the Brigham. He is board certified in general surgery, and he is a member of the American College of Surgeons (ACS) and the Association for Academic Surgery (AAS).

In residency, Dr. Pommerening developed an interest in studying clinical outcomes and completed a two-year clinical research fellowship and a master’s degree in clinical research established by the Center for Clinical Research & Evidence-Based Medicine at McGovern Medical School.

His clinical interests include the breadth of general thoracic surgery, including minimally invasive diagnostic and interventional procedures, lung cancer and advanced foregut surgery. His research interests are focused on designing and conducting clinical trials to advance evidence-based practice in thoracic surgery.

Welcoming New Faculty – Marie Billaud, PhD

Please join us in welcoming Marie Billaud, PhD, as a new faculty member in the Department of Surgery.

Marie Billaud, PhD
Lead Investigator, Division of Cardiac Surgery

Dr. Billaud is a graduate of the University of Bordeaux in France, where she obtained a PhD in health and life sciences, specializing in cell biology and physiology. She conducted her postgraduate research at the Cardiovascular Research Center at the University of Virginia and the Department of Cardiothoracic Surgery at the University of Pittsburgh. Before coming to the Brigham, Dr. Billaud was a research assistant professor in the departments of Cardiothoracic Surgery and Bioengineering at the University of Pittsburgh.

Her research focuses on vascular physiology, with a special interest in cell-to-cell communication, reactive oxygen species, nitric oxide signaling, endothelial function and smooth muscle cell excitation-contraction coupling. She applies her vast expertise in smooth muscle biology and physiology to better understand the molecular and cellular alterations that lead to ascending aortic aneurysms.

Dr. Billaud’s work has been published as original research articles, review articles and cover art in journals such as Circulation Research; Arteriosclerosis, Thrombosis and Vascular Biology; Science Signaling; and the Journal of Thoracic and Cardiovascular Research.
