Bruno Maranhao, MD, PhD
Assistant Professor, Cardiothoracic Anesthesiology & Critical Care Medicine
Department of Anesthesiology Featured Member: March 2020
Bruno was born in Florida and moved to California when he was 11. He completed his undergraduate degrees in Electrical Engineering and Neuroscience at the University of California, Los Angeles before completing his PhD in Bioengineering and a medical doctorate both at the University of California, San Diego. During his MS4 year, he came to Washington University to complete an away rotation in cardiac anesthesiology during which he was constantly having to explain why someone from California would want to move here. It was the easiest question posed to him; the people and the opportunities in the department are amazing. He recommends an away rotation here to every medical student reading this.
Bruno considers himself fortunate to have matched here, and even more fortunate to serve as a chief resident alongside Hawa Abubakar and Dean Thorsen. He is looking forward to his upcoming fellowships in critical care and adult cardiothoracic anesthesiology, both at WashU. Outside of work, he enjoys home improvement projects (he finished his basement during his CA1 year) and spending time with his wife and 1.5 year old daughter. He and his wife are excited to welcome a son in July.

Lukas Matern, MD
Assistant Professor of Anesthesiology
Department of Anesthesiology Featured Member: December 2025
Lukas is a faculty anesthesiologist and intensivist at WashU Medicine. His practice spans surgical and medical critical care as well as general adult anesthesiology. While his current home base is the surgical, burn, and trauma intensive care unit, he also serves clinically as the Physician Leader for Non-Operating Room Anesthesia (NORA) and maintains a strong interest in multidisciplinary care in the main operating rooms. Strongly committed to education, Lukas is engaged in a variety of department initiatives centered on learner development, most recently assisting in the design and execution of critical care simulation exercises. He is particularly passionate about effective clinical teaching and formative assessment, recognizing these as drivers of excellence in medical training.
Lukas grew up in the Midwest but came to St. Louis via Boston. He completed his anesthesiology and critical care medicine training at the Massachusetts General Hospital, where he was chief resident and served as a member of the thoracic anesthesiology group prior to relocating.
In his past life as a conservatory-level cellist prior to entering medicine, Lukas performed chamber works by Schubert, Mendelssohn, and Brahms at Carnegie Hall. He and his partner (a saxophonist) remain regulars at St. Louis Symphony Orchestra concerts, chamber music recitals, and local jazz venues.
