Davi was initially exposed to research during his first year of college in Brazil, in which he participated in lab activities focused on measuring submaximal VO2 in highly trained runners.  In 2007, he transferred to the Department of Kinesiology at the University of Maryland (UMD), where he performed lab rotations to experience different areas of research (biomechanics, cognitive motor neuroscience, and exercise physiology) within the Kinesiology major.  He decided to join the exercise physiology research group, and study cellular and molecular alterations in muscle diseases, including Duchenne muscular dystrophy (DMD) and Lou Gehrig’s disease (ALS).  While at UMD, his research focused on understanding the mechanisms contributing to different diseases and how exercise training and dietary changes could help ameliorate those symptoms.  In 2016, he joined the Center for Genetic Medicine Research at Children’s National Health System as a NIH T32 post-doctoral fellow. Since joining Children’s, his research focused on evaluating satellite cell function as well as the role of the satellite cell niche on skeletal muscle regeneration (regenerative myogenesis) in different mouse models of DMD.  His exposure to different areas of research as well as different models (humans and animals) has given him a broad view of the research spectrum – from studying whole body responses to exercise training to studying cell and molecular alterations in neuromuscular diseases.  While his education and training has been broad, his primary research goal has always stayed the same: to use his knowledge about cellular, molecular, and whole-body physiology to improve people’s lives.

His exposure to teaching started as early as his second year of college where he served as a teaching assistant (TA) for Exercise Physiology.  During his Masters education, he was also a TA for Exercise Physiology, amongst other activity courses in the Kinesiology major.  Since then, he has always been eager to continue educating and mentoring students, not only on the particular class subject, but also on their future academic and professional endeavors. He continued to contribute to teaching by being associated with the Department of Kinesiology at UMD as an adjunct faculty in the Spring of 2017 and 2020, where he taught an upper level undergraduate course (KNES497 - “Adaptations of Skeletal Muscle with Disease and Exercise Training”).
